What is your measurement for your gas blocks?

[Blasternank]

On your bushmaster-What diameter gas blocks do you have on yours? .750"? .875"? .936"?

do they have the same sized ones on their 16" and 20" models?

Thanks.

While I can't speak for the 16", my 20" is .750. I'd wager they are the same for manufacturing simplicity's sake. I took my faux block off and used it on my 6.5 Grendel build. I have a .750 adjustable one I may try some day on the 450b and take off the CCWS to see what it can do. Load up a few stiffies and a few whimpies and see if both will cycle the action with the adjustment optimized for the stiffies. I'm lazy though...

My 16" and 20" 450 Bushmasters are .750 and so is my 450LM.
