So, finally hammered off my M305's Flash Hider

[Gun Lover]

I tried the slow and careful tactic, but that didn't work. A 1lb hammer and small punch just wouldn't do it. However, I still had to wait until it pee'd me off good to finally pull out a 14" x 3/4" cold chisel and 3lb demolition hammer and really bang the crap out of it. Success! The POS Chicom excuse for a FH took off bouncing on my shop's concrete floor and I was a happy camper!

Now, I was finally able to do the 180* trick on my gas cylinder lock and found out it starts to get really tight at around 2:30. It seems to me that that is way too early, isn't it? I tried the rubber hammer thing, but it just gets extremely tight by 4:30-5:00. So my question is: what are my options now, should I shim the gas cylinder and install the lock the way it came, or can I sand the tight side a little to help it get to 6:00?

Also, where can I get a front sight and a castle nut set screw for a GI FH? I've had this FH for a while now and I new I had to use the Chinese castle nut with it, but I didn't realize it did not come with the set screw. The front sight I just want to replace the crooked and deformed Chinese junk that came with my shorty.

Thanks

My gass lock is the same and I am wondering the same about sanding it down to get the right fit ...

options.

buy the shims from brownells $15 pluss shipping,

Gi flash hider... or get a bitsofpieces.com gas lock front site that was made for m305, and put a custom break on like I did....

Sand paper and a flat surface....

Or find some friends and have a swapping party until everyone is happy.

I have done this with a oil stone, but a piece of glass and fine emery would work-The thread is fine-it didn't take that much to move to snug at 5 and tool tight at 6.

That's what I'm thinking. I think I'll try it, if I f*** it up, I can always get the shims and install the lock the way it was, this time over the shimmed gas cylinder. I already have a GI FH to replace the Chinese one.

Hungry has shims and Flash suppressors send him a PM he will sort you out

You only need shims if the gas cylinder lock goes past the aligned position. If it is tight early that's good. The guys above saying to sand the gas cylinder lock are right on.

I have a book on accurizing the M14 and that's what it tells you to do. If it is done correctly, you should be able to tighten with thumb pressure only. No tools are necessary.

Please don't do the above comment.
Either get Dlask gas lock gadget or shims.
As for the GI flash hidder will work but the castle nut will have to remain the Nork 1.

The above is bad advice.

Please sandpaper away on a nice flat surface.
