I got the Ramline lock-arm too and I'll tell you, it seems to be more accurate. I'm not sure if the pistol grip is a factor, or it's a tighter fit..... It's an ugly mother, but it's light. It's my third stock, (it's better than my choate anyway) and I'm sticking with it!!! As for add ons: I'm gonna stick with an Aimpoint ML-2 redot on a b-square, ejector plate mtd. mounted base (although I'm gonna get one of those Ultimaks one day), if you go to my pic you can see the barrel mtd. laser, which I can never remember the name of, but it kicks but for CQB - everyone should have one! I have a clip-on bipod that's nice and light. I guess it all depends on what you want to do with it. I have a Leuplod Vari-X II that I swear by for targets past 100 yards. But, for me though, and for now - this set up makes the most sense. I usually use Wolf HP 122 gr rounds. but this week I should finally be getting the 154 grainers - oh yeah I shoot a mini 30: 7.62x39, but it's the same thing. can't wait to test the 154's!!! If you don't mind $10 per box, PMC makes the most accurate round that I've ever shot. Real brass too. I don't ahbe a trigger job but I lapped the barrel - I'm good to go for now. Have fun man, it's an excuse to buy cool stuff!!!!
