I'm setting up a 10.3 super duty ar pistol with attached law tactical folding brace adapter with BCG insert, what size buffer kit do I need? Expert Answer

The Geissele Premium AR-15/M4 Mil-Spec Buffer Tube Assembly w/ Super 42 Spring will work with the Law Tactical Folding adapter. I recommend using the H3 model of the Geissele Premium AR-15/M4 Mil-Spec Buffer Tube Assembly w/ Super 42 Spring for that set up. However, you will need a pistol brace that is compatible with a Mil-Spec buffer tube.

Is the tube rifle or carbine length? Expert Answer

The tube is a standard MIL-SPEC buffer tube.

Helpful Positive Review Probably the best buffer system you can get. by Fox, Verified Owner, June 10, 2022
The spring that comes with this is the most robust spring system on the market. The dual coiled design is a step above your standard spring and has an extra premium feel to it. The only downside to the Giessele spring/ buffer is that H1 is the lighte...
