gas rings > Maintenance & Cleaning

Why is it that after about 150 rounds at the range, I start having problems with the gas system on my bushmaster 16" ar?

Is it my ammo (wolf military classic and silver bear)? The rifle will fire but wont chamber a new round some of the time (it gets lodged in the chamber crooked).

So I took apart the bolt and re-aligned the gas rings, and fired the rest of my last two magazines, and it fired fine for the rest of the time at the range.

I know wolf is crap, but its cheap and I have a few hundred more rounds of it left...but I wonder if it was just the ammo being junk when the gas rings got out of alignment, and if "better" ammo would have kept shooting good no matter what?

The gas rings being out of alignment theory has been disproved.

Probably a tight Bushmaster chamber + Wolf = jam.

Are you lubing the rifle good before hitting the range?

Sounds like maybe he has a gap between the ramps and the lower. Dad bought an AR from my roommate that does that sometimes. I need to dremel the ramps/reciever.

you didn't break it in enough; or not at all

most New Factory Rifles need to be broken in with at least 200 rounds of good ammo before shooting Wolf.

This is my experience. 4 out of 4 needed a good lube and good ammo for break in. After a good cleaning and re-lubing Wolf works flawless for 800 rounds before jamming from being cruddy.

Clean that rifle, lube it up and shoot it up!

yep, I clean it good after going to the range, and lube it up nice and good. I usually go shooting once a week.

Ive actually put 400 rounds or so of remington umc and some other orange boxed brass rounds (got them at a range)... then I started shooting the wolf. But its only happened w/ the mlitary classic so far and when I mess with the gas ring gaps it stops being a PITA...weird

The gas rings should get a generous amount of lube.

Do you lube immediately before shooting or only after cleaning? I lube lightly for storage after cleaning, then the morning of shooting, I lube for operation.

I can't get wolf to shoot in my Bush M4 at all... jams like crazy. You can immediately follow the jamming wolf with 500+ rounds of Black Hills with no problems.

The Bushies sometimes have issues with the gas key not being staked or not staked deeply enough causing the key to become loose and therefore leaking gas. Check to see if the key is loose. I had to re-stake my Bushies

How does it jam? Short stroke, FTFeed, FTFire, FTEx, FTEj?

I usually lube the hell out of the bolt - gas rings, extractor..all of it. I dont lube the bolt carrier a whole lot. I put a light coating on that. Maybe I should put more on it?

Basically I lube it after cleaning because I shoot every 4-7 days (try to).
