40SW - AR Platform Barrel reference

[NQNPIII]

Haven't touched it. All kinds of projects, haven't had the time.

I'm a lazy guy. (also scared of screwing up the Frontier buffer) The pics I got were really crappy on the bolt mod. I will mod the other one when I can measure the KV lower lip with calipers and save it for a 10mm build, or as a spare. I ordered the Kaw Valley Precision BCG and a .308 buffer spring from JoeBob Outfitters. I think range time will be after Christmas. I also ordered 2 more GunTec 8.2oz buffers. https://www.jsesurplus.com/guntecar9mmbuffer.aspx I have a couple of these in other lowers. I may try one in an AR47.

Got the KV bolt yesterday. No lower nub at all. I will report back after a range trip.

I didn't have a bunch of time when I went to the range. The KVP BCG ran perfect with Winchester purple cased training ammo. About 60rds. I swapped out the 8.1oz buffer and used a 3.0. Not sure it wouldn't have ran with 8.1
