[ARCHIVED THREAD] - 7.5 inch reliability? (additional questions - thanks!)

Posted: 4/5/2006 4:16:03 PM EDT

Please pardon me for such a NEWBY question. I'm planning on using a Mike Rock 7.5 inch, standard LMT bolt, LMT FA carrier, and carbine buffer tube. I have always heard that short barrel ARs were unreliable. How true? Will it go bang with every trigger pull? Thanks.

My 7.5" has gone bang with EVERY trigger pull for about 1,800 rounds so far. I would say that is completely reliable.

You're listenng to the wrong people.

BTW. Closing in on a thousand rounds with 0 problems.

I found that when I switched from a standard stock to an M4 stock, I needed to use an H buffer or a carrier weight to get reliable functioning. I later discovered that using the Noveske Krink flash hider (instead of a heavier buffer) solved the problem, as well.

THANKS FOR THE RESPONSES! I SEE ONE OF YOU USED A H-BUFFER, IS THIS THE COMMON THING TO DO?

DOES THE MAKER OF A SHORTY BARREL SIZE THE GAS HOLE DIFFERENTLY THAN A STANDARD LENGTH BARREL TO ADJUST PRESSURE? THANKS AGAIN FOR THE INFO!

As soon as my Form 1 gets back....
The following is an image from another board member here, I can't remember who.

I e-mailed Mike and he stated I could order it any way I wanted. Chromed, stainless, electroless nickel with silicon carbide, as well as, Nickel boron from from UCT in Florida. I don't know any more than this until I get my Form back and again contact him.
