Fake Gas Block on the 20" 450 B Upper?

[wildcatter]

nope, I want to shut it off while I work up a subsonic round, then I work on a sub that works the action

That's a super good reason for that gas system..t

i installed an adjustable gas tube and it seems to work pretty good, can turn the gas off or can be adjusted to your needs... might be an option if you have a limited budget... http://www.midwayusa.com/viewProduct/de ... ber=396319

just a thought
