This has happened only twice in a few hundred rounds. It'll almost seat it, but won't fire, and it's hard to eject.. but when I do, it looks like this.
Yup the BCG not going back all the way. My long range Ar was doing the same thing. I fixed mine by moving to a lighter buffer and different spring( the original one was a 1" longer than all my other springs... Lol)
Not sure what I've got in it now. It's whatever came with the milspec buffer tube, so given that, what should I try? Pretty sure my buffer is a carbine buffer
I'd make sure:
1. The spring and buffer are good to go (spring good quality like chrome JP or sprinco) and if they are;
2. It's getting enough gas. (gas port/block alignment, clear tube)
My best non-expert guess.
edit: it would be good to know where the ejected rounds are moving to. Barrel at 12:00, stock at 6:00, the brass should be landing in a pile at about 3:30-4:30 about 6-8 feet out.
The brass are 3:00-4:00, but not that far out. I was shooting it laying down, and noticed 3-4 feet out, some were 2feet, some were 4-5ft out.
I've shot maybe 300 rounds of wolf, no issues. And about 200 rounds of brass, and it's happened twice now on brass.
I may just need to upgrade my buffer and spring. I bought it all as a kit, with a stock from a member here, that has an online store for $28. So I'm sure it's not of the higher quality parts. My Magpul stock will come off if you adjust it back and tug on it lol.
Do one quick thing and see if this helps.
Take your buffer and knock the roll pin out. Remove 1 of the weights
Assemble the buffer and give it a go
There's only 1 big weight in the buffer... Do I need to cut a bit off with the bandsaw?
