Adjustable gas block recommendations

[camobob]

I usually shoot my AR suppressed but took the can off this weekend and it didn't cycle.
I'm guessing that it's clogged up. If I have to take it apart anyway I'm considering a low profile adjustable gas block. Am I on the right track? any recommendations on the gas block?

SLR with set screws and pinned.

I'd personally go with the clamp on version.

The way I go is clamp on for precision guns(less stress on the barrel) and screw/pinned for more heavily used tactical and home defense type guns.

Yep.

Don't forget to pack the allen key with you, you'll notice that on colder/hotter days you'll have to make fine adjustments to the gas settings to maintain optimum performance.

Forgot mine on a cold day at DSC, rifle choked on the bulk ammo I brought, had to buy a few boxes of something a little hotter to keep it running right.

Just a suggestion. Use the straw with your can of brake cleaner and spray into your gas tube. That should clean the gunk out.

The SLR block is the one Chad recommends as well, I believe.

I have the strike industries adjustable block from shot show. I love it. I don't think you can buy them yet though. They should be out soon at about 90 dollars

87 Industries is good to go too. Set screw and pinned

Thanks Fellas.
I want to get rid of the milspec sight and was leaning toward the SLR to start with. Went ahead and ordered that along with a new tube. I haven't had to change a gas block before. Any tips?

If you have a FSB, make sure you bang the pins out in the correct direction. They are tapered. It will require good solid force to remove them.

Most are tapered, I have one that isn't (just dowel pinned), but... follow the advice above either way!

Knock em left to right - ejection port facing the benchtop?

 

[Sticky]

Correct..

and it takes a good whack with a big hammer.. lol

Wow - front pin was a little more stubborn than I expected.
Good thing I had a bigger hammer

Funny thing, the gas tube wasn't clogged at all
I wanted to change the gas block anyway but now I'm wondering why the gun didn't cycle in the first place.
What could cause that? The BCG looked okay. Not clean but not excessively dirty and still had oil on it. Cycled fine with the handle. Ammo was good (XM193)
Any ideas?

Did you check the gas key for obstruction or constriction? Run a piece of string trimmer line through it all the way into the piston cylinder(where the tail of the bolt resides).

Who can pin a SLR block locally for me?

What is "locally" to you?
