Ar Help

[littlered]

Anyone ever had a feeding problem with their AR. I took mine out for the first time this past weekend, it was a build with DPMS lower, standard 18" A2 Upper. But what it was doing is, load a round and then it wasn't picking up the next round, but sometimes it would. I was able to get it to pull 5 rounds and then the next 6-8 I would have to manually rack it, and then it would fire a few and stop again. I'm looking for any suggestions
Oh I did try 3 mags, 1 colt, 1 Bushmaster, and one new one, and it still had the same problem with all three.

what type of stock and recoil spring and spring weight are you using ?

[littlered]

just a plain stock, and i have no idea on what kind of spring, this is all new to me so

[The Extractor]

Is it clean and lubricated ? brand new, or used parts in the upper ? is it completely ejecting the empty shell ? What type of ammo ?

The mags all seat well? Send Me a PM,, I could look at it...

My friend Pat had the exact same issue with his DPMS last weekend as well. New rifle & everything. I am curious to see what the cause is... What type of followers were in your mags? I have got some magpul anti tilt followers in mine & they really do not tilt! The green ones still do from time to time. I suspect that the magazine housing may be a little tight on Pats rifle (being brand new) it might not hurt to release and reload a couple twenty times to help smooth things over a bit, although this is just speculation. I have a few different kinds of Magazines and followers you can try if you think that might be the cause.
Let me know... I am in Thornton.

My AR had a problem with FTF (failure to Feed) turns out it was really dirty though.

I would take Marlin up on his offer, he could save you alot of time & money on trouble-shooting. JMO Good luck.

I'm speculating, but are you saying you assembled the upper yourself or? This sounds like a gas issue. Meaning not enough is getting back to the chamber to cycle the bolt. If you've got a rifle length buffer and spring you should be fine there - specs can be found via google -

Gas issue. Possibly debris in the gas key like what happened to mine.
