840815122654 The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in 300 Blackout® (300 BLK). Since its inception, 300 BLK shooters have had to use a magazine designed for another cartridge, limiting its ultimate performance and compatibility. One of the key features of 300 BLK is the compatibility with 5.56x45mm parts, but with the magazine, it is a compromise to do so. Due to the wide variety of projectile weights and profiles potentially decreasing overall reliability, a dedicated 300 BLK magazine was a logical step for the PMAG line. In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B also offers a safer way to feed your 300 BLK rifle. When using 5.56x45mm mags, the potential to chamber and fire a 300 BLK round in a 5.56x45mm rifle with catastrophic results requires diligent ammunition management by the shooter. The PMAG 30 AR 300 B’s distinct rib design and smoother upper-half texture provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues. Along with optimized 300 Blackout performance, the PMAG 30 AR 300 B incorporates all of the GEN M3 features such as Magpul’s next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, and a paint pen dot matrix for marking and identification. FEATURES Purpose-built magazine only for 300 BLK Dedicated magazine for rifles chambered in 300 BLK that supports the differing geometries found in that caliber. The result is a more reliable magazine Designed with visual & tactile differences - Distinct rib design and smooth upper-half texture provide visual and tactile differentiation from other PMAGs to mitigate dangerous cross-loading issues Incorporates the same features and performance of the Gen M3 line Next-generation impact and crush-resistant polymer, aggressive front and rear texture, easily removable slim floor plate, and a paint pen dot matrix Made in the USA. SPECS Caliber: .300 AAC Blackout Platform: AR15, M4, M16 Capacity: 30 rounds Weight: 5 oz. Length, max: 7.5 in. Compatibility: Wide compatibility with most 'STANAG 4179' platforms such as the AR15/M4, FN SCAR, IWI Tavor, and others NOTE: DOES NOT INCLUDE DUST COVER.

Brownells USA Great 300 BO Magazine 23/07/2018

I bought these along with the Lancer 300 BO magazines. When I loaded the magazine, I noticed it rattled very loud. I was skeptical but after shooting many rounds, performance was flawless. The Lancer magazines seem like better quality however the Lancer mags were not as reliable - had trouble feeding 30 rounds flawlessly. Magpul works great with various grain weights (120,150,200) - my go to 300 BO magazine

Brownells USA They are exactly the same quality 05/07/2018

I am really happy with my 300 blk magazines. The magazines are light weight and has a great texture. I've used many magpul magazines in the past and I would say these are the same quality as the other 5.56 magazines. Many comments suggest poor construction and rattling of the bullets but that's because of how the bullet is constructed. You can use a 300blk bullet in a 5.56 magazine but the bullets will kind of bind to the side of the original magpul 5.56 magazine. For them to flow freely through, the reinforced area where the 5.56 would easily slide up was shaved down to adapted to the 300 blk. The reason why they might feel lighter and poor quality is that material was taken off so the 300 blk would not bind to the walls but that does not effect the functionality or the reliability of the magazine. If you are still skeptical about them, buy 1 and compare why these feel different from the original 5.56; and the reason is 5.56 is not 7.62. The 7.62 is larger so it needs more space. Yes, they rattle but that's not something I worry about and if you have only 5 rounds in the magazine, it doesn't rattle. Even if you're out hunting at night, why would you load all 30 rounds? I would say one good shot or two would do the trick but if you need more than that, don't go hunting.
