Okay, got a PTR 91 GI on order, in the mail and in route to my FFL. I am pretty pumped...it is my 3rd HK clone for the herd. Got my order in to RTG for some extra goods. I do have some questions for PTR GI owners.

1. Can you recommend some bulk ammo that worked for you?

2. I am gonna check bolt gap and try and run 100-200 rds through it and see how it goes.....see where the gap goes. I want to eventually duracoat the gun hk black. I know I have 1 year warranty and I read a lot of threads on this and other forums. My rifle is in the 800+ serial number range.

At what point would you feel I am good to go with bolt gap settling in and trunnion checks before I am good to go for the actual duracoating?

3. Any other recommendations? I will get the RTG G3/91 survival kit at some point.

THX in advance.

Here's a group I shot today from my 91-G.I. with Privi, rifle is barely broken in with a bolt gap of .013. Shot from a lead sled at a indoor 100 yard range. Rifle has been fire-lapped, PWS brake, Bill Springfield trigger,MSG-90 heavy buffer,B&T low profile mount, Burris extreme Tactical rings that were lapped, Burris 3-9x Ballistic Plex LRS. It shot sub-MOA with .942" group but My HK-91 set up exactly the same shot .477" group with a handload, here's the pics

Here's a old pic of my HK-91

Thanks Seasmoke. I got the survival kit ordered. Any other must haves you guys can recommend?

Great groups. What was your handload data? Or are we not allowed to share load data on this forum?

Also, how much of a difference did you see before and after fire-lapping? Thinking of using David Tubbs' system on my PTR-91sc.
