Ready for a suppressor with maximum subsonic accuracy.
Nothing feels better than putting together a new AR, sending some rounds downrange, and ringing steel – especially with a suppressor muffling subsonics. That’s exactly what this 300 BLK AR pistol kit is intended to do: Its 7.5″ heavy barrel, featuring a 1:8 twist rate and pistol gas system, is ready to reliably and accurately cycle both supersonics and subsonics, with or without a suppressor, providing tight groupings that are whisper-quiet.
What’s Included
This is not a firearm. It includes an assembled upper receiver, bolt carrier group, charging handle, lower parts kit, and buffer system.
