Sticky AR bolt....

OK, yeah I guess I didn't say with a magazine and cartridges...

Having this same problem with my brand new bushmaster upper.  Wouldnt close all the way, i pull back charging handle and cartridge stays in chamber.  I drop charging handle again and push it in, VERY hard to pull back, when it does, the cartridge comes out stuck in the bolt face, scuffed up brass when i pop it off.  Switched ammo types and tried again, only this time i cant pull the charging handle out, its flat stuck.

Slam the butt of the rifle down on something while trying to pull the charging handle,it will come out.

A lot of places are cutting chambers so quick these days.

Did you ever cancel that bear crk rifle or does your bear crk rifle work better than your new bushmaster upper

Bango, did you drop your magazine? this helped when mine stuck a couple of times while trying to figure it out.

Well, that was easy hitting the butt on a stump to pop the charging handle out, and this time the cartridge didnt stick to the bolt doing it this way.  Heres a pic showing the chewed up brass on the rim of the cartridge.

The bca rifle works fine.  I just built a new lower, and im about to do my. 223 wylde upper for it, but first i popped this complete 450 upper on to try it out.  Not going so well.  But wanting to make sure i didnt screw up my lower build, never having done it before, i took my upper off my bca rifle and put it on my new lower, and it worked properly.

Yeah

Didnt expect to have problems here, its not a cheap upper.  Next level armament.  Has a tromix barrel.

@Bango
I'm gonna urge ya to just go with a ar10 ,with some of that 💰. Ar15 is very addicting,but once you bump up to ar10 YOU wont  play with them anymore.Been seeing 243,6.5,308 are popular these days.

[Bango skank]

Im not looking to buy an ar10.  This upper should work.  It was 800 dollars and took a month to get it.  Pretty bummed.  Cant find anything stuck in the chamber, dont know what the deal is.

Thinking the chamber wasn't cut right?
Are you able to unscrew the barrel?

Do you even own one?

You've been giving a lot of suggestions about ARs on this forum that are questionable, at best.

Wow -Holly smokes
I put my my whole ar10 together for less than that.There probably is ways of fixing it .but for that money I would get my money back.

Didn't see you giving him advise on how to get his stuck round out of the chamber .You got a better method maybe chime in next time.

Yondering seems like he knows what he is talking about he can give ya advise.

The brass is getting scuffed all the wsy down, so maybe, but the barrel came dirty so it had to be test fired 

Having never put together an upper, im not going to take this one apart.  Yet.  I just finished my first lower, and now im about to put together a 223 wylde upper.  Once i do that, and see how all the bits and pieces go together, then ill consider breaking the 450 upper down.  But i dont have headspace gauges for the 450, so i dont kniw what i could accomplish as far as determining whether or not the chamber is out of spec.
  From what i can see, when putting a cartridge in the chamber with the bcg removed, the cartridge sits flush right here, where the taper starts.  Dont know if this is normal, or if its supposed to sit deeper.  This is all new territory for me.
