The two main reasons I bought this was to get a better grip installed and use a Geissele SSA-EX trigger. The SSA-EX does not fit, it is too wide to go in-between the safety detents! But I am giving it 5 stars anyways because with some modifications that more than likely voided my warranty I got it in there and functional! This is all I ever wanted since I got my APC223 last year, thanks B&T.

Shipping was fast, packaging was minimal, and the lower had a scratch on it. Nothing bad, but a little upsetting after spending $450

A little tight on my Gen 2 APC223 Pistol (original lower was fixed grip). The tight fit seems like it really stiffens up the gun. Function checks all passed, Elftmann trigger installed with no issue. Swapped the B&T grip to Magpul K2+ for a more vertical grip - makes the gun way more comfortable to shoot. A bit spendy, but it’s a worthy upgrade!
