Took my new 9mm SBR to the range last night. Not a very good night as I experienced a lot of jams. Mostly FTF.
Here is my set up
RRA Factory 10.5" Upper
9mm Hammer, Buffer, Spring
Stag Lower and LPK
Hahn Dedicated Mag Block
RRA Polymer Magazines.
I only had 2 mags for it basically what happens is dropping a bolt will result in a round pushing up and jamming right above the chamber. Easing the bolt back a little and letting it go again chambers the round.
Ammo tried
IVI Nato Load, 147 Grain Federal and 147 Grain Rem +P
I'm thinking and maybe the combo of 9mm Buffer, RRA carrier is to heavy and slamming too hard on the round to push it up. I think I'm going to try Carabine buffer next.
Any opinions?
