16" SPR

Why the KNS pins??? Unless the lower receiver is out of spec and the pins walk, these are worthless.

When I replaced the trigger I had in it with the Geissele SSA, the first time at the range, the hammer pin starting walking out. I had not had that problem with the other pins. Installed the KNS pins, since I already had them on-hand, to omit any problem. I use to have that lower on my Mk12 Mod 0 build and had a LMT 2-stage trigger installed. No issues then.

If the pins walked with your SSA it means it wasn't installed correctly.

Or the lower is out of spec.

Or it is very old with a very high round count. That is why I have a set on one of mine.

What kind of round count?

Not really sure but I have had it for about 18 years and I would guess in the area of 50k or higher on that one. All parts have been replaced three times.

Thanks, everyone.

I still haven't gotten it zeroed. I've had it out to the range a few times but it was with other people and we were shooting for fun and I didn't want to shoot up my good ammo (CBC 77gr SMK).

I have a box of Fiocchi 77gr SMK, Hornady 75gr TAP (80265), Federal TRU 55gr Hi-Shok SP (T223A, was KCPD load a few years ago), and 10 rounds of Hornady 55gr Z-MAX that I'll shoot for groups the next time I get a chance. It's been too windy the past couple days, also the Royals have been playing.

Noob question here: since both your CBC and the Fiocchi are using the same Sierra 77gr bullet, won't they shoot the same?
