Another Grendel comes to life!

Possibly. Just depends on your gas port size. Grendels tend to be over gassed and an adjustable block allows you to tune it down a bit.

What would be an indication that it's over gassed? Flying brass? I don't want to nullify my heavy buffer with over gassing, kind of defeats the purpose.

Mine's over gassed and it would kick the brass out at 2 o-clock maybe 4'-6'. Once in awhile, when bench shooting one shot at a time, an empty wouldn't clear the receiver and end up laying on top the magazine follower. Also, dented brass 1/2 way down the body. Solved these problems with a heavier recoil buffer and an M-16 bolt carrier. In the future I might go to an adjustable gas block, we'll see.

Did you put that upper together yourself or have it done? I am looking for something very similar, but can't find anyone that is able/willing to do it. Might have to take it on myself.

Big dents on the sides of brass is one indicator of being over gassed. After installing and tuning an adjustable gas block on my rifle, the dents in the brass completely disappeared!

You want the brass ejecting at 3 o'clock give or take a little. Typically, if it's ejecting 1-3 o'clock it's over gassed. 4-5 o'clock, under gassed. If you already have the heavy buffer you may be OK.

Good to know, I'll be sure to check my brass and have my buddy see where it's ejecting. Depending on weather I may get to shoot tomorrow.

aclark- a friend of mine has built several so I actually went over to his place and we put it together. Where do you live?

[aclark]

Indiana, unfortunately...I may end up buying all the parts and doing it myself/with friend(s), but part of me just wants to have it done and be sure its top quality.

[FiremanTx]

Understood, with the help of you tube and this website, they aren't terribly difficult to build. I understand just wanting it done though.

Well, off to the range, hopefully I will have good things to report and pics to see!
