Having short stroking problems

[jackthewall81]

Having short stroking problems. New Daniel Defense M4. I would fire one or two rounds then it would jam or short stroke. My bolt carrier screws are tight, and the gas block, gas ring and bolt appears to be tight and not letting any gas escape. Gas tube and everything appears to be ok. I am thinking it might have to do with the crappy ammo (Wolf and Tula), the magazine (magpul), charging handle, buffer or buffer spring. I am going to replace the handle and buffer spring and buy a new magazine as well as better ammo. I am also going to get some new Break Free CLP to help with the lubercation. Not sure what else to do. Any advice will help. Thanks!

It's the ammo. Before you start replacing anything shoot some good ammo. m193/855 will do. If you still have problems then you can start troubleshooting other stuff.

Lol, I thought this was gonna be more "personal" in nature. I was gonna say I think there's a pill for that, but nevermind.

A buddy's DD runs fine with steel case... in fact that's all he runs through it.
Shoot some brass case ammo just to eliminate that from the equation, but my money's on something else.

Thats a problem as well...

mccantar, Man I hope not. I got a Daniel Defense just because they are know for not having problems. Just my luck.

buying a box of 20 Federal 5.56 is ALLOT Cheaper than replacing any of the above mentioned parts

try that first, consult with your local gunsmith if this fails.

Its possible that the crappy ammo might not have enough power to cycle a brand new gun.

After all the parts break in then the wolf and tula might be fine.

[jackthewall81]

Ill try new ammo out tomorrow. Thanks guys.

Also save $ on CLP, just get yourself some nice heavy weight motor oil to lube it and maybe some CV joint grease to replace expensive fancy greast for your high friction areas.

Make sure that chamber is clean as well.
