View Full Version : gas plug/gas block problem
June 15, 2007, 09:26
I just got an Imbel kit and noticed that when the gas plug is screwed into position A (A facing up), there is nothing holding it there. I can simply give it a twist and it comes out. Shouldnt the cross pin hold it in? If I set it so the G is up, it will stay in position. The recesses in the gas block are kind of worn, so is this a problem?

Sounds like you may need a New gas block or gas plug,Do you have another gas plug you could try in your gas block to see if it fit any better than your original gas plug, you can buy new Belgian gas blocks from www.gunthings.com for about $45.00 shipped ,and they also have Good Condition Used gas blocks properly removed from barrels for $35.00 ...................http://gunthings.com/falfront.htm

The new-condition gas blocks are exactly that. New. As in virgin.
They have not been previously drilled for the cross pins. Unless you have some very good machine tools, or are a much better-than-average hand-drill operator, a virgin gas block is going to be a nightmare to install properly.

Hey Gary, You are right and I should have mentioned about the New Belgian gas blocks being Virgin and needing machine work for the retaining pin in my reply to his post ,his best bet would be to either buy a used gas block and swap it onto his Imbel barrel or just buy another barrel all together

Here are some pictures of what I have. Notice the gap between the pin and the groove on the block. What do you think?
Simplest solution, get a grenade sight gas block. It doesn't use the cross pin to lock. The sight blade keeps it from rotating.

Those do sure look like some worn parts.
I'd try a different gas plug first, it's the cheapest, maybe borrow one initially. If that doesn't work because the gas block itself is too worn, elbo's got a good suggestion. Otherwise, it's time for a different gas block, which is not an easy project, but probably better than having to remove the entire barrel and replace with something different.

I think I will replace the whole thing. I went ahead and took off the gas block and I know I can get a new/used one from gunthings, but where can I get a new plug? DSA has some, but I dont think they have the right one and gunthings doesnt list them. I would like to get one that matches the one I have.

Try the old plug in the "new" gas block first, and see what happens.
