Make 300BLK Integral To Your Life – YHM ULTIMATE Upper Receiver

    YHM Ultimate

    Do you enjoy the sounds of silence? Ever considered getting a ‘subsonic’ lower back tattoo? Named your second born child ‘Blackout’? Make pewpew sounds in your sleep? If any of these descriptions apply to you, Yankee Hill Machine has just released a new setup that should probably be on your wish list. The YHM Ultimate 300BLK Top End is a  AR15 upper receiver that has a Phantom suppressor pin and welded to the barrel for a length that will avoid a second $200 Short Barreled Rifle NFA tax stamp. The silencer under the 13” handguard gives theupper an integrally suppressed look.

    Yankee Hill Machine is known for making quality guns, silencers and gear at affordable prices. Partnered with quality subsonic ammunition, the Ultimate Top End should make for an extremely quiet setup. Details, specifications and links can be found below.


    This is one not to miss! Check out the new ULTimate™ 300 Blackout Top End! The ULTimate™ comes with a .30 cal. Phantom® ULT titanium suppressor which is pinned and welded to a 9.1″ .300 BLK barrel. With the Phantom’s length of 7.625″ and the barrel length of 9.1″, this gives the ULTimate™ a legal barrel length of over 16″. Also included is our brand new, lightweight Black Diamond® M-LOK® rifle-length handguard for a bold, sleek look. Built with the flat top A3 upper receiver assembly, it already includes the forward assist and dust cover assembly for your convenience.

    It’s like getting an SBR and suppressor, but with a single stamp tax!
