Any recommendations on .223/5.56 NATO ammo.

 

has a weird issue with shooting my AR Sunday. It fired off 3 rounds just fine, then it jammed with the feed. So i dropped the mag, cleared the jam and checked it all and then charged and shot one shot and it did it again. Since it was a new build i was a little frustrated but more curious as to why. So i experimented with my friends BCG and it did the same thing but after a full 10 round mag it stove piped on me. I have a T2 buffer in mine and mine is a mid length gas system. So i swapped buffers with the same friend who let me swap the BCG. Still randomly would jam. So i tried a different brand BCG from my brothers AR and everything worked flawless. The two BCGs my AR didnt like were BCM. The one it did like was a Spikes BCG and standard carbine buffer.

I also noticed, which i've found after googling that mid length's do not like PMC ammo. I was able to put about 5 mags through it with my brothers BCG and friends carbine buffer no issue. So i ordered a Spikes BCG and standard buffer. Hoping to go shoot this weekend and have no more hiccups. With non PMC ammo though.

 

Pic cause everyone likes pics

 

My first thought was to question if all 3 bolt carriers were Auto or Semi, but a quick check of BCM & Spike's websites shows their branded stuff is all Auto. Hopefully the new BCG will sort the problem for you.

 

There are alot of nice AR's on here, but I love my piston colt 6940.

 

Their triggers are good to go.

Colt made a piston rifle?
I have a 6940 but it's DI.

 

I was going to get the regular Colt 6040 but found a great deal on the piston. I don't think they make it anymore, its not on their website. Its exactly like your 6940 colt mil-spec stock, colt rails and magpul sights

 

Interesting.

I have a PWS 10.5" piston. Didn't know Colt made them.

 

I was just on the Colt website and it's not listed on the consumer side. Look on the Law Enforcement/military site and you will find one. It's really pricey, Retail is in the $1800 and up neighborhood (if you can find one).

 

Sister company of Geissele if that tells you anything
