PMAG® D-50™ LR/SR GEN M3™

Magpul PMAG D-50 Product Details

The Magpul PMAG D-50 is a rugged, lightweight 50-round polymer drum magazine designed for 7.62x51 NATO/.308 Winchester ammunition for SR25/M110 pattern rifles. It’s capable of using longer-than-SAAMI-spec match ammunition, up to 2.830” OAL, such as M118LR. Engineered to the same exacting standards as the famous Magpul PMAG and PMAG D-60® drum magazines, the D-50 continues the PMAG tradition of high-capacity performance and dependability.

Durable and Reliable

The Magpul PMAG D-50 incorporates proven GEN M3 technology, which includes next-generation impact and crush-resistant polymer construction and the ability to seat fully loaded on a closed bolt. Robust stainless-steel internals withstand corrosion and long-term storage while loaded with no loss of function, spring fatigue, or reliability concerns. A slip-on semi-rigid dust cover prevents grit and debris intrusion during storage and transport.

Easy to Use

A ratcheting loading lever removes spring tension, making the D-50 easily loadable by hand. An anti-glare translucent window on the rear of the drum makes for quick positive visual indication of remaining ammunition. Additionally, the D-50 can be disassembled quickly with a simple flat blade screwdriver or similar tool and it comes with a dot matrix pattern that allows for easy marking and identification

Lightweight, Compact and Affordable

At approximately 1.7 lbs empty, and 4.5 lbs loaded, the Magpul D-50 is one of the lightest 50-round 7.62x51/.308 drums available, and it’s priced well below the current competition. The D-50’s unique drum configuration gives it roughly the same overall height profile as a standard 25-round PMAG, making storage easy and shooting from various positions–including prone–no different than with smaller capacity magazines.

Magpul PMAG D-50 Specifications

*Optimized for use only with 7.62x51 NATO/.308 Winchester cartridges.  Use with other calibers such as .260 Remington or 6.5 Creedmoor is not recommended.

Gas Block Genie Gas Block Alignment Tool

Just spotted this on Brownells. Interesting, inexpensive and reusable tool for proper gas block alignment. Currently only available for .750 barrels but other sizes are coming.

Ever put together an AR build, only to find that your semi-auto cycling system just doesn’t cycle? Looks like that gas-block installation didn’t go as well as you thought it did. Avoid future frustration by adding the Two Two Three Innovations Gas Block Genie to your AR building kit.

Unlike other gas-block alignment tools on the market, the Two Two Three Innovations AR Gas Block Genie Gas Block Alignment Tool can be used again and again, as many times as you want, during your AR build. All it takes is three simple steps.

The type of gas block doesn’t even matter when using the Gas Block Genie. Whether you’re working with clamp-on designs, rail-block designs or micro-size options, the Gas Block Genie can handle it all!

Gas Block Genie Gas Block Alignment Tool Instructions

The Gas Block Genie quickly and easily allows you to perfectly align the AR-15 or AR-10 gas block hole with the gas port in your barrel every time.

  1.    Squeeze the Genie slightly to install into the forward face of the gas block so that the hole in the Genie is centered on the gas block hole. It may be easier to remove the rearmost set screw to do this. Part of the Genie should be sticking out the front side of the gas block
  2.    Use a very fine point marker or scribe to make a mark on the Genie where the forward edge of the gas block is. Make a small mark on the gas block at the slot in the Genie to indicate the top center of the gas block. It may be helpful to use a black marker on a stainless surface and a silver marker on a black surface.
  3.    Remove the Genie from the gas block and snap onto the barrel so that the hole in the Genie is centered around the gas port in the barrel.
  4.    Transfer the mark you made in step 2 to the barrel through the slot in the Genie.
  5.    Remove the Genie and slide the gas block onto the barrel.  As the Gas block approaches the barrel’s gas port you will see the line on the barrel and the mark on the front face of the gas block.  Simply align the two and you are finished!  A perfectly aligned gas block!

308 AR M-PRO 7 AR15 CLEANING KIT

M-PRO 7 AR 15 CLEANING KIT

Brownells has teamed up with M-Pro 7 to develop the M-PRO 7 AR15 CLEANING KIT. This cleaning kit specifically for maintaining an AR-type rifle in peak operating condition. Now you can clean your AR using the same operationally tested products used by the United States Armed Forces.

Inside the kit’s compact hardshell case you’ll find M-Pro 7 Gun Cleaner that safely penetrates deep beneath even tough, scorched-on carbon fouling to lift away the gunk and leave the bore sparkling clean. M-Pro 7 Cleaner/Lubricant/Protectant delivers superior lubrication and corrosion protection, and can also be used for quick cleaning on the go, when there isn’t enough time for the complete cleaning routine.

You get a military-style multi-section steel cleaning rod with a folding handle, plus five high-quality bronze brushes to clean ARs in the standard .223/5.56mm and .308/7.62mm calibers, as well as 9mm and .45 chamberings, plus a brush for cleaning the bolt carrier way—critical for maintaining reliable weapon cycling. There’s plenty of absorbent cotton flannel patches in three sizes to fit all those calibers, plus the M-Pro 7 Weapons Maintenance Guide. Due to its non-hazardous and non-flammable contents, this kit meets TSA regulations for legal transport in checked baggage aboard commercial airliners.

LANTAC .308/7.62X51MM Enhanced Full Auto Style Bolt Carrier Group NiB Coated E-BCG

Lantac Enhanced BCG Full Auto Style E-BCG Enhanced Bolt Carrier Group 308

LANTAC .308/7.62X51MM Enhanced Full Auto Style Bolt Carrier Group NiB Coated E-BCG

I find it interesting that two of the most expensive .308 bolt carrier groups are designed with philosophies that are 180 degrees apart. The JP Low Mass 308 Bolt Carrier Group is a lightweight BCG that must be used in conjunction with JP Rifles Low Mass Recoil System. On the other end of the spectrum is the Lantac E-BCG .308 part number LA00300. In a market of “me too” inexpensive bolt carrier groups Lantac differentiates itself with superb quality, brilliant engineering and patents that deliver one of the best performing BCG’s available.

The Lantac E-BCG is designed to be weight balanced from front to back. This makes for a pretty heavy bolt carrier group. The added weight increases lock time and should theoretically reduce recoil. That additional mass combined with the BCG’s NiB  coating lubricity equates to smooth cyclic function. Lantac has designed “Port Forward” channels into the carrier body to direct gases out and away from the bolt. Suppressed shooters will really benefit from these features. Lantac designed a round gas key or “smooth cam”. To me this is a halfway point between the POF gas key which is a ball bearing and a standard square gas key. The Lantac E BCG cost about twice as much as traditional quality carriers and that hasn’t stopped it from becoming wildly popular. In fact other manufacturers such as ADM offer it for sale among their own hardware. Lastly it’s a crazy sign of the times wen you can spend $300-$450 on a 308 bolt carrier and for about one third more buy a cheap and complete AR-308/AR-10.

Lantac Enhanced BCG Full Auto Style (.308/7.62) LANTAC E-BCG™, Enhanced Bolt Carrier Group.

The LANTAC E-BCG Enhanced Bolt Carrier Group is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 and Magnetically Particle Inspected. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process, unlike standard NiB coatings. This offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C.

The carriers patent pending design features unique shrouded and forward facing gas ports that have also been re sized so that gas is vented differently to a standard carrier. This results in a system that runs flatter with a smoother energy pulse. In addition, the system also runs cooler and cleaner and there is also less pressurization of the upper receiver when running a suppressed barrel. The flared boss at the tail of the carrier enhances the BCG’s lock position within the upper and makes it more consistent, resulting in an accuracy improvement.

All critical dimensions are hard turned / ground after heat treat and the bore of the carrier and gas key have been hard chrome lined for the best possible wear resistance. All E-BCG’s feature the LANTAC CP-R360 patent pending domed cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx). The ultra-smooth head reduces wear within the upper receiver. Gas keys are properly staked at four points and only grade 8 fasteners are used in assembly.

All critical dimensions are hard turned / ground after heat treat.
All E-BCG’s feature the LANTAC CP-R360-H™ patent pending domed cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx).
The ultra smooth head reduces wear within the upper receiver.
The BCG’s weight helps to increase lock time with smoother operation.
Gas keys are properly staked at four points and only grade 8 fasteners are used in assembly.

The E-BCG’s forward porting and unique shape assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors.
However, it should be noted that the E-BCG™ is not a complete solution for this issue and all rifles are different. ‘Over Gassed’ guns will suffer to a larger extent from this problem.
