Easiest way to clear a plugged gas block?

[BigDotGlock]

A while back, I threw some parts together into a .22 beater AR. Since I was only ever planning on shooting .22lr out of it, I figured a gas tube would just get clogged and I didn't bother putting one on. Now I miss my my other short AR, decided to trow a real bolg group in it...but the gas block is full of crap. The gast tube needs to go in abou t3/16" farther than it can

I tried knocking the front sight pins out, from the proper side for a RRA, they won't budge. Is there any way I can clean it out well, without taking it off? Open to anything at this point, chemicals, voodoo, virgin sacrifice, I want to shoot real rounds out of this thing.

Thank you in advance.

Can you use a jewelers screw driver to scrape it out?

I've been scraping around with small screwdrivers and whatnot, hasn't helped. I'm wondering if there wouldn't be copper and lead in there, that got up through the gas port, from all the .22lr that went down the barrel.

Pipe cleaner?

 

[BigDotGlock]

The obstruction is forward of the gas port, a pipe cleaner wouldn't do any good with the mess I made.

Small drill bit?

Soak it with Butch's Bore Shine over night and I'm sure it'll rinse out.

I would go with this, maybe blow it out with compressed air afterwards.

I'll get my hands on some bore shine and give it a shot. Drill bit would make the job easy, but I can't get at it properly withouth taking the pooping the stubborn pins and removing the sight.

Are you sure the port is clogged? Did you try shooting it with centerfire ammo?

And what would that prove? It's a single shot at the moment because the gas tube cannot be installed.

You're going to have to remove the front sight. If it did somehow end up severely clogged with lead what would removing the portion forward of the gas tube accomplish aside from being to install the gas tube? You'd still have a possible obstruction in the gas port of the barrel, no way to know until you pull it off.

I don't shoot .22 in my uppers but I find it highly unlikely that you'd have so much build up that it would preclude the installation of the gas tube, something else is probably going on here. FSB or gas tube could be out of spec.

 

[raks]

Ah, missed the part about it not being installed.

True, I'll go fight with it a while longer. Might as well do it right, rather than end up teaching folks at the range some new cuss words when my AR doesn't cycle.

Wipeout works extremely well on softening carbon build up, it's a bore cleaner but works super well on carbon fouling in piston ar's.

I ended up getting it to fit this afternoon. Took about two hours of soaking with bore cleaner, scraping with a small screwdriver and a drillbit by hand, and a few dozen f-bombs.

Now, if my range and the CFO ever get around to getting me my 2012 ATT, I'll go see if I did a good enough job.
