So I was messing around with my dm13, and when I went to unscrew the lpr, it was all the way tight, but the gun shoots fine. When I'd loosen it, it gets really loose to where its really easy to screw/unscrew with my fingers. Is this normal?
Yah the back cap can be finger tight, the LPR adjuster is a totally different allen key size.. You dont normally mess with it unless you're taking lpr out (every 60k shots)
for your dm13, set your dwell to 21 and turn your LPR brass adjuster till it'
s stiff, basically that's when the piston hits the LPR seat, then do 3 1/2 COMPLETE 360 degree turns. and u'll be good to go
