Dummy gas block

[BayouBob]

This has been discussed before but I can't remember where. Does the dummy gas block on the 20" 450 serve any purpose at all? Does it serve as some sort of vibration dampener or anything? I am thinking about lightening up my Thumper by putting a lightweight handguard and a light stock and if the dummy gas block is just for looks I may remove it just to shave a couple of ounces.

I took mine off and haven't noticed any difference. That gas block now is serving a very useful purpose on my 6.5 Grendel. Hoot gave me that suggestion as he did the same thing. That gas block costs about $56.00. So save it for a future project. Or you could just mail it to me as a late birthday gift!!

just for looks.

Dawg, Is the barrel finished under the block?

Its actually for mounting some Bushy front iron sight systems (made by YHM)...non-functional other than that.

[BayouBob]

Commander, I saw that front sight in the old paper Bushmaster catalog 4 years ago but haven't seen them since. Do you know if they are still made?

[commander faschisto]

Not sure...I bought one and mounted it as the front BUIS...if they're not in the Bushy catalog, you might check Yankee Hill Machine? Sorry I can't be more definite...

How hard was it to remove? I assume you have to remove the flashider but what else is involved?
