The "Modern" AR thread.

[Bulls-I_24]

My local shop had a couple cases of the CCI AR tactical, I may pick up more today, although I would like to find some more mini mags. Both my AR's have unpinned FSB, the Bushy having the ARMS flip that is clamp on and the M&P has a cheap low pro with I believe 2 set screws with loctite. I havnt had any problems but I havn't shot enough .223 to be able to tell.....I doubt the .22lr will budge either of them
I I'm currently in the tool and die business and the p.f. dowel pin holes we ream are either to size or .001 under, same with th guide pins, sometimes the pin bores are .oo2 under and we put the pins in the freezer. Those dies exert a lot af pressure and the dowles and pins never have a problem moving or coming out...I guess my point is the FSB must be really tight cause I also tried pushing them out on a small hydrolic press. I know if I had a dedicated fixture for holding the upper the press would have worked. I think its more of a job security thing for gunsmiths az they don't want "bubba" working on their rifles and getting hurt?
I know this is off topic but, does anyone use Tapatalk on their mobile? Stevo, I can see your pics from your last post fine but from my last post I can't. I have to load it in the web to see them, and I assume you just uploaded them aand attached them inline with your post?

I also think the cut down FSB is better than anything you can buy. Having tried the alternatives several times, I finally accepted that "Bubba'd" is better than store bought.

I'm often surprised at the number of guys who will slag you for cutting a pinned FSB down while preaching the use of a set-screw or clamp-on block. It's a critical point in the whole AR system and the pinned FSB isn't going to let you down!

I have used clamp blocks with no issues and the set-screw block is fine if the barrel is dimpled.

My pics are hosted on Photobucket and I copy and paste the image link into my reply.

Tell me true Bulls-I_24, is your barrel a chrome lined 1/9 twist? If not then what? I have a CMMG insert and had trouble with it in a couple other type barrels. They were un-lined though.

Yes it is. Have you tried the heavier 40 grain? The newer gen kits are supposed to cycle subs, I will be trying the CCI subs I have tomorrow, 1050fps 40gr. I would like to try some 60gr subs but dont have any. The 20in 1/12 barrels should group the best but I don't have one to test that theory. What yardage where you sighted at and what distances did you shoot? I think being sighted in at the calibers maximum point blank range would help. Does chrome lined help with accuracy? I thought it was for corrosion resistance? This spring I will definately post some 100yd groups.
