Barrel lock-downs

[proffrink]

I've run into an issue with my M249 that plenty of us have had - locking down the inner and outer barrel so the inner isn't wobbling around in there. This is particularly a problem with the Daytona kits because they shake a lot and any rattling is severely detrimental to accuracy.

I've use electricians' tape in the past, but I find it's too spongy to really make the barrel cease movement completely. The obvious solution is just simple shimming with anything like thin bits of metal or plastic. I was just wondering if anyone else had done anything similar in the past and had any wisdom to share on this?

Someone recently suggested coiling paper.

I use PTFE tape with a bit of electrical tape at either end to stop it being moved.

Aluminium foil.Use loctite 222 to glue it to the barrel so its easier to remove if you need to.

You only need to use five 10mm strips one at each end and three evenly spaced in between.
