Built a heavy barrel AR, which gas block????

[kustomkat1950]

I want one with a rail to put a bipod on, built this for my 11 yr old....super heavy rifle, 17 lbs so far.

Which gas block should I use? 20' upper, think its .930...

Is that other barrel for sale?

[kustomkat1950]

PM me.

I wouldn't put the bipod on the barrel. If that handguard is free-floated, drill the muzzle end of it for a QD sling stud and attach the bipod there.

[kustomkat1950]

see, this is where you guys chime in. I never would have thought of that...

17lb rifle puts red dot on it to save weight.. Com'on man! you can easily add 3-5 more pounds with a giant telescope mounted on top of that bad boy. Then off set the red dot at a 45 degree for MAX weight.

11 years old + 17 pound rifle = DO YOUR KIDS EVEN LIFT BRO!

Never really got an answer....

Can I use the .936 low pro gas block? All I have seen is that seems like that is for AR-10?

There's not really a difference AFAIK. I Googled "ar15 .936 gas block" and got a ton of retail results back -- Troy, Midwest Industries, YHM, etc.

[steelheadmike]

Yep, any 0.936 GB should work. Go lo pro if you want to fit it under the HG.

[baih777]

any .936 will work.
here are a few.

I just drilled a FF handguard and mounted a sling/bipod stud a couple days ago. I bought a pack of Ny-Lok nuts for this one since I've had some work loose with the standard nuts.
Be sure to put stud far enough back to fully support the bi-pod, and it'll be easier to get the nut on before the gas tube/block is in the way.
