The Ultimate Optics Guide to Rifle Shooting
As I mentioned in previous posts I am not typically a “Brand” guy but as a rare exception I’m becoming a fan of the Vortex Optics brand. This morning over coffee I was scanning the Vortex Optic site for 2016 products when I happened across the All About Optics Brochure. I found it to be nicely done and informative in a down to earth manner. Being a curious guy I decided to research who wrote it. It appears the author is CPL. Reginald J.G. Wales a technical field advisor for Vortex Optics. Upon further research it turns out CPL. Reginald J.G. Wales is also the author of a book from Vortex optics called “The Ultimate Optics Guide to Rifle Shooting” from Vortex Optics”. The Ultimate Optics Guide to Rifle Shooting was released in December 2015 and has no reviews at the usual places. The book can be previewed on Google Books and purchased from Google and Amazon in Hardback, Paper and Kindle versions. I was hoping the kindle version would be less expensive but it’s the same as the paperback. I ordered the paperback. Look for feedback and a review in the near future.
The The Ultimate Optics Guide to Rifle Shooting is a comprehensive manual that teaches you everything you need to know to use your optical scope to its maximum potential. Although showing you how to use your scope to hit the target is the author’s top priority, he also teaches you how to use your scope for other tasks, such as zeroing in at different ranges and using your reticle to calculate range, measure objects at a distance, adjust for wind and elevation, measure unknown bullet drop, and much more.Packed with illustrations and equations and loaded with practical exercises that help you apply what you learn, this book will raise your shooting skills to a whole new level. Whether you are a competition shooter, a hunter, or a law enforcement or military professional, this book is an invaluable addition to your marksmanship toolbox. The author, Cpl. Reginald J. G. Wales (CAF, Ret.) serves as a certified firearms instructor and also a technical field advisor for Vortex Optics (Canada). In this book, he draws on experience in the military and as a firearms instructor, a hunter, and competition shooter to teach you how to get the most out of your scope on the range, on the hunt, and on the battlefield.

CMMG Mk47 Mutant AKM2
I have a fondness for CMMG. This fondness comes from the fact that in an industry saturated with with a lot of “me too’s” CMMG seems to always be searching creatively for a little niche to call there own. In the past we have seen 308AR/AR-10 rifles that utilized HK G3 magazines, a multitude of .22lr AR15 upper receivers and accessories and handgun cartridge chambered AR15’s before they were popular. In fact I have an early CMMG Sierra as will as a 9mm upper. I enjoy both. Todays post comes in the form of the CMMG Mk47 Mutant AKM2 76AFC41. It’s a mutant because and I will quote CMMG here “combining the accuracy and modularity of the AR-15 with the reliability of the AK47“.
Anyone out there have or plan on getting the CMMG Mk47 Mutant please take join the forum and share your results.
The CMMG Mk47 Mutant AKM2 is a new platform for 2015, combining the accuracy and modularity of the AR-15 with the reliability of the AK47. The Mk47 features all new mid-sized receivers based on our Mk3 platform carved from billet 7075-T6 aluminum. The Mk47 was designed to harness the power and reliability of the 7.62x39mm cartridge utilizing a robust bolt also based off our Mk3. The unique Mk47 lower receiver readily accepts all standard AK Magazines. Every rifle comes equipped with a MOE pistol grip, SV muzzle brake, Geissele SSA trigger, 30rd AK PMAG, and CMMG’s lifetime quality guarantee.

When it comes to advertising/sponsors relationships at 308AR.com and our family of sites and communities it’s no secret we are very selective with advertisers. Today we are excited to add Hiperfire to the list. Hiperfire offers AR15, 308AR and AR-10 triggers for most budgets $89-$275 and shooting disciplines. I had been planning to purchase a Hiperfire Hipertouch 24C but now Im feeling obligated to get the Hiperfire Hipertouch Eclipse Trigger ECL listed lower in the post.
Hiperfire Hipertouch Eclipse Trigger Description
Click the second thumbnail under PRODUCT PHOTOS (above right) to view a comparative feature summary of the HIPERTOUCH® trigger group family. Also, consult the Resource Center (RESOURCES navigation button) where you’ll find items like the Hiperfire Hipertouch Eclipse Trigger Troubleshooting Guide
HIPERTOUCH® 24, 24E, 243G, and 24C Specs Plus these Enhancements
- Nickel Alloy Finish Applied to the Hammer and Trigger
- Smoother Trigger Pull
- Prolongs Useful Cycle Life
- Can Be Easier To Clean
- Sports a Black HIPERSHOE®
- US Pat. Nos. 8,572,880, 9,052,149 and 9,175,917, Others Pending
The HIPERTOUCH® ECL4 is HIPERFIRE’s top-of-the-line trigger for AR-15® and AR-10® type rifles. The HIPERTOUCH® name is short for HIgh PERformance TOUCH, 24 for user adjustable trigger weights. The ECL was developed as part of a 3-gun promotion. But, one must realize that this and the other triggers aren’t just for 3-gun. It now sports a new evocative name since its performance eclipses that of even HIPERFIRE’s 24C. It installs and functions just like all the HIPERTOUCH® 24s. For installation and operational features of the HIPERTOUCH® family of AR fire-controls, go to the HIPERTOUCH® 24 page and watch the videos. View this graphic,Hiperfire AR-10 AR-15 Lower Cavity Dimensions. HIPERTOUCH® FCGs may not work in lowers with pivot holes that are outside the MIL-Spec dimensions shown in RED.
HIPERTOUCH® FCGs have uniquely solved two problems with stock AR triggers and AR trigger upgrades respectively: 1) High Trigger Weight, and 2) Low Hammer Fall Energy.
Trigger Weight: The real culprit behind high trigger pull weight is high sear impingement force that produces high friction. To get around that, the stock “AR” trigger and hammer mechanical advantage was changed and the toggle spring feature added to reduce the impingement force on the trigger sear. Designers of two-stage products changed the functional location of the primary sear; HIPERFIRE®’s design has not, retaining the stock design’s single-stage simplicity. This is important for when stock triggers are pulled, the hammer cam-action signals hammer fall is imminent. When 2-stage triggers are pulled, the final higher weight stage also signals hammer fall. This can lead to the flinching problem we all know about. Some like to say the better 2-stage triggers have glass rod or candy-cane like breaks to sell the idea that they don’t signal hammer fall. In any case, the HIPERTOUCH® ECL does not signal hammer fall because the trigger weight is constant over the entire stroke.
Hammer Fall Energy: HIPERTOUCH® features the unique toggle spring functionality that reduces trigger weight, but while doing so, it also increases hammer fall energy by over 35% over the MIL-spec stock design and every trigger upgrade in the market. This permits the shooter to ignite hard MIL and foreign primers as well as hard to ignite 22 rimfire ammunition.
HIPERTOUCH® FCGs retain Eugene Stoner’s design of simple elegance while remaining very robust, without the gritty feel. Shooting for high accuracy is no longer an almost impossible chore. It’s no longer necessary to improve the stock performance by manually polishing the high-friction trigger and hammer sear surfaces, where the end result was only marginally better anyway.
Ambitious sportsmen and marksmen have been turning to trigger upgrades with varying degrees of satisfaction. The better replacements have been one and two-stage triggers with fixed final weights ranging from between 2½ and 4½ pounds with what some have called a glass rod or candy cane trigger break. Some of these devices require factory or user calibration, maintenance, and/or replacement for wear or doubling. Some of these devices also employ reduced power springs, which have compromised reliable ignition for a “dream” trigger weight.
The HIPERFIRE® “AR” accessory response to those shooter’s looking for a single-stage and very much improved, match quality, “AR” trigger upgrade that delivers high performance is the HIPERTOUCH® ECL. It nests in unmodified standard AR-15® and AR-10® type lower receivers in the same way as stock “AR” triggers and hammers without having to remove the safety selector. It is comprised of three subassemblies: the trigger, hammer, and toggle, spring groups. All the parts are made from carbon steel alloys that have been hardened for wear and strength. It features exceptionally low trigger weights with smooth pre-travel, a very clean hammer release with no report to break, match action response, and faster hammer lock-up. Only now with HIPERTOUCH® trigger and hammer actions does “AR” trigger “squeeze” have real meaning.
Additionally, the HIPERTOUCH® ECL also sports the HIPERSHOE® adjustable finger pad as first introduced with the 24C, which can be positioned at five (5) different vertical detent locations along the straight trigger’s bow. By changing location, the shooter can further adjust pre-travel and weight within the broader spring range settings than without it as desired for even more trigger responsiveness. Also, the adjustable pad lengthens slightly the extension of the finger to the pad with respect to the pistol grip, which alters the feel and dexterity of the finger on the trigger for added comfort and/or control. The trigger can be installed and operated with and without the shoe.

Aero Precision 308AR OEM Rifle – As I have previously mentioned on our AR15 sites I really like the concept of these Aero Precision OEM rifles. They consist of completely assembled rifles without a sights, buttstock and handguard at a cost savings greater than the sum of the omitted parts. Basically we are not forced to buy parts we never use. Well today I decided it was time to see what was going on at our best supporter Brownells and low and behold they have a ” Brownells Exclusive” Aero Precision 308 AR OEM rifle. Priced right about the price of the no frills least expensive 308AR rifles from other manufacturers. In my opinion the Aero Precision 308AR OEM Rifle is a better quality value.

Drake TiTAN Titanium Barrel System – Our friend Chris Drake at Drake Associates just passed on this news release for your viewing pleasure. If your unfamiliar with Drake Associates and their line of rifles and chassis you just might recognize them as the folks behind the Remington XM-2010 and Remington MSR.
Drake Titanium Stalker
The Drake Titanium Stalker also features the lightweight, Drake TiTAN Titanium Barrel System. This precision rifle was designed as an alternative to the military’s M24E program, with a similar mission profile that features high performance options at an affordable price.
The Drake TiTAN Titanium Barrel System by Drake Associates is a HIGH PERFORMANCE, LIGHT WEIGHT, LONG RANGE PRECISION BARREL SYSTEM that is manufactured under a US patent-pending process that increases the strength and reduces barrel weight by as much as 45%. An important application for the TiTAN™ Barrel System is a upgrade and retrofit for US Military and US Law Enforcement sniper weapon systems, Civilian Tactical Shooters and Long Range Hunters precision rifles.
If you’re looking for a high performance barrel system, the TiTAN™ will not disappoint. With the weight of a sporter barrel in a titanium heavy profile contour, this barrel system is no match for carbon fiber wrapped barrels.
Drake Associates currently offers the Titanium Barrel System with the Hunter Stalker and Drake Stalker Rifle Systems. Also available to order for Remington and Savage Bolt Action rifle systems as well as AR15/AR10 and 308AR rifle systems.
Drake TiTAN Titanium Barrel System for AR-10/308AR Rifles
We probably get just as many questions about the best scope for an AR-10/308AR as we do out the platform hardware itself. The Vortex Viper PST 6-24x50mm FFP Riflescope EBR-2C MOA Reticle 43127 will be a first in a series of Vortex scope purchases for this and our other sites. The Vortex Viper PST 6-24x50mm FFP Riflescope EBR-2C MOA Reticle 43127 was intially ordered for a a MDT TAC21 project at modularrifle.com. However based on the price point half way between the inexpensive scopes and premium scopes the Vortex Viper PST 6-24x50mm FFP Riflescope EBR-2C MOA Reticle 43127 might just be exactly what many AR-10 and 308AR rifle shooters are looking for. We purchased ours online here.
Vortex Viper PST 6-24x50mm FFP Riflescope EBR-2C MOA Reticle 43127 Description:
One of the most common questions we get on the forum or facebook is “CAN I USE AN AR15 TRIGGER IN A AR-10 or 308AR?“. Well the answer is not black and white. Most AR15 triggers will in fact physically fit and function in a current AR-10 and 308AR rifle. However the reason AR-10 and 308AR specific triggers exist is for one main reason, military primers. The primers in military ammo often require more energy to ignite the primer than .223/5.56 ammunition. The way they extra energy is achieved with a heavier hammer and a more powerful hammer spring. If you look closely at the picture above you can see that Pact in their AR Gold and SR Gold Triggers increases the height of the hammer slightly to gain the extra mass.
There are many shooters successfully using AR15 TRIGGERS in their AR-10 and 308AR rifles however the risk is reliability. Our suggestion is always utilize a trigger that is specifically stated by the manufacturer to work in a AR-10 and 308AR rifle. There is typically no cost difference unless you want to utilize the least expensive triggers or a AR-15 TRIGGER with a TRIGGER JOB. In either of those cases I would have to ask why bother? Remember a quality trigger is the single best improvement you can make to any AR-10 and 308AR rifle. Skimp elsewhere.
- $65 – ALG DEFENSE ADVANCED COMBAT TRIGGER (ACT) – While listed as an AR15 TRIGGER. It is listed by the manufacturer as a AR-10, 308AR Trigger
- $113 – J P ENTERPRISES – AR-15/AR-STYLE .308 ADJUSTABLE TRIGGER SYSTEM
- $189 – CMC – AR-15 TACTICAL TRIGGER GROUP – CMC triggers are listed as AR15 TRIGGERS but according to the manufacturer suitable in AR-10 and 308AR rifles. The CMC line of trigger probably represent the best value in performance versus cost. The CMC line of triggers is my recommendation for shooters who can’t afford the $280 triggers. The differences in performance are so close the average shooter might not be able to tell the difference.
- $279 PACT SR GOLD TRIGGER MODULE – I know the Geissele has developed a massive following. For my finger the PACT ATC SR GOLD has been and still is my favorite 308AR TRIGGER.
