A2 does not cycle

[esaabye]

I have an bushy A2 20inch Hbar and it is no longer cycling correctly. Today it ran fine for 30 rounds then slowly turned into a bolt action rifle. The bolt would catch 3/4 back then not at all. Same load I normally shoot and that shot fine from a 16inch today so I think it is the rifle.

Where do I start looking for the problem?

I cleaned it tonight, dripped some clp down the gas tube and it drained fine.

You and me both guy!

You inspired me.

Just a strange thing, worked fine for 1st several thousand rounds but now, bolt action.

Think I must have plugged up the gas port or the tube but not wanting to take it apart yet.

I have never seen a clogged tube or port to much pressure. I don't advise sticking anything down it either You probably wont get it back. Check for binding of the carier and gas tube by stripping the bolt carier and runing it up and down by hand listen and feel for any binding. I would bet this is the problem aspecialy if it works well the first mag or so it is fouling and binding. Clean the gas/carier key out realy well soak it over night in brake cleaner then scrape out the carbon fouling wich is usually hard as a rock from being baked in. Also no ball powder or laquered cases.

bushy with bushy mags? i have seen several bushmasters that with factory supplied mags are unreliable. try some other mags, that fixed the problem with the ones i am familiar with.

Gas issue.

Check your front sight for leaks.

Maybe it needs some oil..
