Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
Short cycling
I have been having an issue with one of my AR's short cycling(I dont know if thats the right name or not).
I load up a mag, pull the slide back and release. Pop off the first round and the slide does not go full cycle and doesnt grab the next round. I can see it stops short, and doesnt extract the spent case either.
What would cause this, and what are some tips for fixing it?
Thanks

Gas ports not ligned up on gas block, or rings damaged, worn, all notches lined up? Or gas tube/port plugged? That would be my guesses.
Take it to Bowers', Rob will fix you up. But tricavscout is right.
Yeah this weapon is almost new, only had a couple hundred rounds through it. I can see that when I pull the charging handle back that it is not going into full battery. something is restricting it.

Uhh if its not going into battery, don't shoot it.Originally Posted by spleify
What gun is it, or what are the parts?
Yeah, hard to diagnose this over the internet. Possibilities run from incorrect extractor, incorrect action spring, short chamber, incorrect locking seats, incorrect bolt, damaged or incorrect cam pin, damaged or improperly installed firing pin retainer, worn or damaged gas rings, Bent or damaged gas tube, clogged gas tube, mis aligned gas block, and even including an improperly tightened or loose barrel nut.
Just pop by the shop and we'll figure it out.

Reloads or factory ammo?

There already seem to be some pretty smart folks on this (aside from Hoser) but you might add incorrect (too heavy) buffer to the list of possible culprits for the bolt not fully cycling. For the weapon not going into battery... I'd say get it to a someone to check out before you shoot it again. But then I'm kind of attached to my skin. YMMV.

Just a SWAG but I'm gonna guess the gas key is the culprit. Loose would cause the short stroke (leaking gas) and also the FTGIB if it is misaligned.
I have noticed a few new rifles with poorly fitted/staked/torqued gas keys.
