Which gas block?

[Billinthedesert]

Just about have my parts together to send to my armorer buddy to assemble my Grendel. I am using the Monster group-buy 20-inch barrel, with "gas block journal of .7495." Can anyone recommend the right gas block, and possibly an adjustable one as well? I am assuming the adjustable block permits some tuning if running bullets that are either on the light or heavy side of normal, or am I confused? Very possible.

JP makes a couple of great adjustable gas blocks.

I'm useing wojteck lately they work great and don't break the bank.

The JP split yoke type is still my fav due to I can take it off the barrel and not have to remove my muzzle device.

Just make sure you get a .750 profile, just about all adjustable gas blocks are good these days.

I put a JP adjustable gas block on my 20” Shilen 6.5 Grendel. I don’t run a suppressor and have not had to adjust the gas block since installation a couple thousand rounds later with various bullet weights and powder combinations. Unless your running a suppressor I prefer the simplicity and reliabilty of a fixed gas block. If a suppressor is in your future I’d recommend an adjustable gas block, adjustable carrier key or adjustable gas carrier.

The 20” 6.5 Grendel barrels with rifle length gas system are generally well balanced and reliable.

Thanks guys. No suppressor in my future. I'll just go with a non-adjustable for my rifle-length gas system barrel.

JP, Superlative and SLR All make great Adjustable gas blocks!

I like my seekins adjustable block. Pretty low pro and really easy to use.

I’ve got Odin, Seekins, and PSA adjustable gas blocks. All get the job done.

JoeBobOutfitters has an inexpensive $30 AGB that I put on to see what difference it made - HUGE! I'm not saying how great or how long it will last but my brass comes out at 4 o'clock not all beat up no matter what load I use.
Just saying that whatever you choose will be money well-spent.

I'm partial to the adjustable carriers. My first adjustable gas system was with an SLR gas block but every build since then has been with either Bootleg or 2A Armament adjustable gas bolt carriers.

I'm still working on my build but I have a Superlative block on my list

+1 for SLR blocks! Only ones I use!

Another +1 for SLR GBs...

I just put one of these on my 20" Grendel- love it. I was getting pelted with brass with the non adjustable AP gas block- now my brass comes out at 3 o'clock.

Anybody used the Mentium steel clamp on AGB? I know it's budget but have been very happy with this gas block and super easy to adjust and tune for the gun.

No, but the $45 'USA' bipod looks like a Chinese clone of an Atlas.

This is your first post... Where is it all made?
