As an owner of an Adams Arms piston rifle, I can say that I love my piston rifle. It is reliable and eats just about everything I shoot without fail. When I started a .300blk build a few months back, I was looking at having my gunsmith convert a standard Adam’s Arms kit to .300blk. Now Adams Arms has released a new .300blk line, with uppers in both 14.5″ and 9.5″ barrels. Both are also also available as complete firearms.
No word on if they plan to make a conversion kit that will be .300blk compatible, right now their site only lists 223/556 conversion kits. I would hope that they would release a conversion kit in the near future for those building their own uppers. Here is the press release from Adams Arms.
Adams Arms is very proud to introduce their new line of piston driven 300BLK products, complete with the Adams Arms legendary Lifetime Warranty and accuracy guarantee. Our new line of piston driven 300BLK uppers and pistols are available in multiple configurations and barrel lengths with the same clean running, reliable system you have come to expect from Adams Arms and the accuracy and durability of Voodoo Innovations Melonited barrels, combined with the benefits of the .30 caliber 300BLK cartridge.
Adams Arms 300BLK uppers and pistols are perfect for your home defense, hunting, and sporting needs, where you need more punch than 5.56/.223 can provide, while maintaining low recoil and flash signature benefits of 5.56 in a compact AR design.
One of the main benefits of the 300BLK cartridge is shooting suppressed to increase reliability and reduce sound signature. The Adams Arms piston systems include adjustable gas blocks for your various shooting applications and to accommodate a wide range of subsonic and supersonic ammo. The XLP gas block gives the shooter the ability to fine tune their rifle. The Adams Arms piston systems run cleaner and cooler, offering a more reliable option for shooting suppressed without extreme fouling or carbon build up resulting in failures.
