Product description
High-Quality Black Nitride Bolt Carrier Group For Your 9mm Build
This AT3 Tactical™ 9mm Bolt Carrier Group features meticulous machining and a high-quality finish for a lifetime of use. This bolt makes a great partner for any Glock or Colt-compatible AR-15 blowback barrel, so you can make a completely custom build to suit your needs.
The black nitride finish features excellent hardness and lubricity, which means this BCG is durable, easy to clean, and less reliant on lubrication. It weighs in at 14.6 ounces total, and has a removable rear weight for compatibility with JP and Armaspec recoil springs.

Questions & Answers 9

Will this work in a PSA ARV7 that takes Scorpion mags? The bolt face looks almost the same. This gun also has a Partison FRT in it
Scott · Jun 14, 2026AT3 Support Team — No, the Palmetto State Armory AR-V requires a proprietary bolt carrier group designed specifically to feed from CZ Scorpion magazines, so a standard AR-9 BCG will not work.

Got a 5.5" Saint Victor 9mm with dead air wolfman, kynshot RB5007 Hydraulic Buffer, sprinco blue Flatwire spring, and Franklin BFSIII Elite Limited trigger group. It shoots okay, got a little bounce and was thinking of changing the Franklin trigger for a Geissele SD-3G Trigger that is cut for my Hoffman super safety. Will this bolt accommodate the Geissele SD-3G with Hoffman super safety and help slow my bolt travel? Is it a Mercury percision bolt under at3 trademark. Which would you recommend the kak enhanced or the at3?

Does this one have the weight cut back enough to accomodate an FRT? I vave tried several and the levers keep getting stuck on the weights with my current bolts. Textac design recommended this one but I just want to ask before I throw any more money at this.
Ryan · Apr 10, 2026AT3 Support Team — Yes, the AT3 Tactical™ 9mm BCG has a removable rear weight that you can take out or trim to clear FRT levers—Textac's recommendation is spot-on, as it's specifically designed for this purpose unlike heavier BCGs that bind.
-
Is this BCG full auto rated?
Kaleb · Jan 31, 2026AT3 Support Team — Yes, the AT3 Tactical 9mm BCG is full auto rated, featuring a robust heat-treated 8620 steel carrier with black nitride finish, MPI inspection, and enhanced geometry for reliable high-round-count performance in AR-9 builds.
