[ARCHIVED THREAD] - Reliability issues with barrels?

Posted: 8/4/2005 11:04:10 AM EDT

ok im strongly thinking i want to do a pistol build. my question has to do with barrel length.
i like the look of a 7 1/2in barrel but would i be better off doing something longer like a 10 1/2 or 11 1/2? another nice part about going longer is being able to use a carbine gas system. after dealing with a finicky AK i really like my guns to go pop every time i pull the trigger.
or would i be ok doing a 7.5 with a krink flash hider?

thanks in advance for any input

Generally speaking, you shouldnt have any issues with the 7.5in barrel as long as you choose a good buffer system (Ace, CAR, or Entry Tube type) Almost all the issues with the shorter pistols resulted from bolt bounce, weak springs, bad buffer design (M1S type)...

I've had a few 7.5's and once I went with a better buffer system, 100% reliablity wasnt a question.

cool thanks.
what i was thinking was a 7.5 from model 1 and get a free float and a pistol gas tube while im at it from them and then a CMT flat top upper and CMT standard Bolt/carrier assy

and also i have a stripped Rock rivers Lower that was transfered to me as a stripped lower and not as a rifle and i have a recept that says stripped lower and then the serial #, would i be ok useing that for my build or would i be better off ordering a Pistol Lower from a place like LCW?

thanks for input

Well, personally, I'd spring the extra cash for the Marked lower, although some feel its unnessesary...

I always felt weird about shooting my pistol when it was unmarked, so I sold the lower and picked up a marked one. (just my personal taste)

do what you feel is right.

Good discussion, I am a thinkin' I'd go with the 10.5 or 11.5 just for the velocity boost. Would be good to have M193 fragmentation velocities out to at least 50 to 75 yards. The kitty cat barrel lengths seem like they would be a lot handier, but what kind of fragmentation range would we get in a 7.5 inch with M193? Or for that matter, what frag range for the 77 grain Sierra Matchkings? Otherwise would probably be better off planning on softpoints for the AR pistol, right?

cool thanks, ill order a marked pistol lower then. better safe than sorry.
fragmentation? i look at the pistol as nothing more than a way to waste ammo

Parabellum, good point, what a fun way to waste ammo too.

So far my M1S "old style buffer tube" is running okay...but I'm running a 10 or 11" barrel....
