CRADDOCK PRECISION DPMS G2 BARRELS

As I mentioned elsewhere on the site Bartlein Barrels known to make some of the most accurate rifle barrels in the world does not make barrels for the 308 AR, AR .308 platform. Instead they send customers to Craddock Precision. In turn Craddock is quickly making a name for themselves for making the most accurate 6.5 Creedmoor and .308 Winchester 308 AR Barrels from Bartlein and Criterion Barrel blanks. Now they are very forward thinking in offering the same accurate barrels for DPMS GII (DPMS G2) and equivalent rifles.

Craddock Precision G2 Rifle Barrels 6.5 - Creedmoor and .308 Winchester

Do you have a shiny new DPMS Gen2 and cant get it to group consistently? Well this barrel from Craddock Precision is the best aftermarket barrel you can buy to throw into your rifle to make it shoot accurate!
You can choose from a Bartlein, or a Criterion Blank. Prices will vary. We also offer fluting on these barrels as well. You can pick from straight fluting, spiral fluting, and diamond fluting. This option would add 1-2 weeks on your barrel.
You may choose a bead blasted or polished finish. Bead blasting would make your barrel a matte gray and polished would be a nice high shine finish!

GEISSELE 308 HI-SPEED NATIONAL MATCH TRIGGER SET

Hi-Speed National Match Triggers
Geissele Automatics currently offers three large pin Hi-Speed trigger products. These adjustable triggers are specially designed for competition, hunting, tactical, and military use, where both accuracy and robustness are critical. As an adjustable trigger, the first and second stage weight distribution, as well as, total pull weight, over-travel, and sear engagement are all to be tuned to the shooters preference.

The Geissele Service Spring Set
The Geissele Hi-Speed Service is designed for NRA High Power Service Rifle competition. It is an approved trigger for use in CMP sanctioned competitions such as: National Trophy, NTIT and all Excellence In Competition matches. Service Rifle competitions require military-based weapons to meet certain criteria, one of which is a minimum trigger pull weight of 4.5 lbs. Our Service Rifle Trigger includes our exclusive 5-Coil trigger spring which will give a nominal 4 lbs. on first stage. The Service trigger pull weights are biased with most of the pull weight on the first stage. This will allow a light second stage with an icicle-sharp break, effectively giving your weapon a match-grade trigger let-off.

The Geissele DMR Spring Set
The Geissele Hi-Speed Designated Marksman Rifle is designed for tactical and military shooting where trigger pull weight is not regulated. Perfect for all precision tactical shooting and squad Designated Marksmen, the higher second stage weight helps in high-stress shooting situations.

The Geissele Match Spring Set
The Geissele Hi-Speed Match is designed for NRA High Power Rifle competition with highly modified AR-15 Space guns. AR-15 Space guns are the Formula 1 weapons of High Power Rifle competition. With very few restrictions, these highly customized semi-automatic weapons are intended to produce extreme accuracy at long range. The Geissele Match Trigger is a perfect Space gun add-on as the pull weight can be adjusted to low levels that enhance trigger control. The fast lock time assists the shooter in getting every ounce of accuracy out of his weapon. The Hi-Speed hammer uses a full-power hammer spring which imparts more kinetic energy into the firing pin, producing much more consistent primer ignition – especially with experimental cartridges or AR 308, 308 AR and AR-10 based weapons.

Precision Armament M41 AR 308 Muzzle Brake

by Donald Sullivan | Jun 22, 2017 | Muzzle Brakes | 0 comments

Precision Armament M41 308 AR Muzzle Brake

The Precision Armament M41Muzzle Brake may not have the “tactical” or “aggressive” look that many 308 AR rifle shooters seem to prefer today. What this muzzle brake does have to offer is proven performance in the field and that is what really matters. Most Precision Armament M41owners are shocked at how well this muzzle brake reduces felt recoil on the .308 Winchester and .300 Winchester Magnum calibers. You can read many reviews of the Precision Armament M41 muzzle brake at the “learn more” button below.

Learn More

A few items of interest to note. This muzzle brake like many others needs to be timed to the barrel. That simply means the muzzle brake has a very specific horizontal orientation. This is so the blast goes away from the shooter and not towards the ground. Simply tightening the muzzle brake to the barrel will result in a random orientation. The use of a crush washer or Rocksett thread locker are the best methods to achieve proper orientation. The crush washer is the easiest method but least attractive. The Rocksett is the best solution. This is the same method used with muzzle brakes and flash hiders with silencers and sound suppressors. (see below) To avoid damaging the muzzle brake finish Precision Armament suggests using a spanner wrench which they offer. (see below)

We will be using the Precision Armament M41 sibling the M11 308 Muzzle Brake on the 6.5 Creedmoor Long Range Sniper Rifle at our Modular Rifle Site. There’s also some discussion on the forum

Precision Armament M41 AR 308 Muzzle Brake Installation Guide

Precision Armament M41 Severe Duty AR 308 Muzzle Brake

Three large axisymmetric baffles, each featuring five helical ports, redirect a massive volume of gas away from the bore axis in a counter-clockwise radial direction. This not only provides maximum recoil reduction but also reduces the torsional recoil force associated with heavy bullets and fast twist rates. High tolerance class-3 threads machined in same operation as bore aperture ensures perfect concentricity; this combined with a progressively decreasing baffle thickness and maximized venting area significantly reduce bullet flight disturbance resulting in less yaw, higher BC, and improved accuracy. Computer FEA optimized for maximum strength to weight ratio and impact survivability. Precision CNC machined from high strength HTSR 400-series stainless steel bar for superior heat and corrosion resistance. Offered in either an ultra wear resistant DLC (Diamond-Like Carbon) matte black finish, or stainless steel in-the-white, matte finish.

This muzzle brake is designed to fit 5/8-24 threaded barrels and can also be modified by a qualified gunsmith to fit larger thread diameters (up to 3/4″ or 18mm).

Available in three calibers:

6.5mm / .264 Caliber (for use on rifles .22-.264 caliber)
7.62mm / .308 Caliber (for use on rifles .264-.308 caliber)
8.6mm / .338 Caliber (for use on rifles .308-.338 caliber)

Official Armalite AR-10 Lower Receivers | AR-10A | AR-10B

Armalite AR-10 Lower Receivers!

Armalite AR-10 Series “A” Lower Receivers can utilize Magpul LR 308 PMAG Magazines as well as other DPMS LR-308 compatible magazines!

Armalite AR-10 Series “B” Lower Receivers utilize Armalite proprietary magazines originally derived from M14 magazines!

As if the 308 AR versus AR-10® platform debate isn’t confusing enough Armalite brings confusion to their own platform. Armalite AR-10 lowers are available in two styles. The original AR-10 A series and the AR-10 B series.

Why does Armalite offer two different AR-10 lowers? Original Armalite “waffle” magazines are actually the basis of DPMS LR-308 and KAC SR-25 magazines. During the 1994 Bill Clinton Assault Weapon Armalite decided to switch designs to the modified M14 magazines to ensure customers would have an ample supply of 308 magazines.

Armalite AR-10 Lowers

Armalite AR-10 lowers will not win any beauty contests but when you buy authentic AR 10 lowers you are buying battle tested hardware that has withstood the test of time. That’s more than most other 308 AR manufacturers can say. The Armalite AR-10 is the real deal.

Official Armalite AR-10 Lower Receivers

AR-10 is the registered trademark owned by Armalite to prove it. No other firearm is an AR-10 no other manufacturers weapon should be referred to as an AR-10. Armalite is the only AR-10® period. Referring to any other brand 308 AR as an AR-10 only adds to the confusion of the platforms
