Input On Adjustable Gas Blocks?

[NHPiper]

Hi all,

I am running a RRA 20" Varmint upper with a rifle length gas tube and buffer system. The gas block is .936.

Any recommendations on a good, low profile adjustable gas block? I have looked at the Syrac and a few others. Hard to find any in-stock in that size.

I will be so bold as to say this is the best choice on the market at this point in the game: https://suparms.com/collections/adj...-gas-block-bleed-off-clamp-on-melonite-finish

Not associated with them in any way. I am not a fan of adjustable gas blocks and I have tested bunches of them, but when you need one, and need reliability, you can thank me later.

That one caught my eye too. What makes you not a fan of the adjustable blocks? I am running my gun suppressed and unsuppressed, about a 50/50 split.

What makes you not a fan of the adjustable blocks?

Erosion in the block due to choking the flow, leakage, reliability, maintenance, damage of gas rings.

SLR Rifleworks, I have 3 of their gas blocks now and they get very dirty, but I have had no issues with them. Superlative Arms is another that seems to get good reviews.

Its funny, but I never expected adjustable gas blocks to cause problems or get dirty. First time I have heard of it.

First I heard of problems other than cheap set screw adjustable blocks.

I like my Seekins, but I'm not sure they make one in .936.
However I have a buddy running a .936 JP Lo-Pro Adjustable gas block and that thing is an absolute beast. It is low-profile, but I don't know if it's any lower or larger than any of the other .936 offerings because I've never seen any others firsthand. Looks pretty slim though.

No problems with either.

I have a seekins, JP and slr. I like the SLR the best. It has a leaf spring locking mechanism that is automatic and reliable. I don't like the set screw locking on the JP as nearly as much. The seekins adjustable block seems cheap compared to the others.

Whatever you choose, make sure the adjustment works well with your handguard. Some require front access, others side access and several need access from both directions, one for locking and another for adjustment. Depending on the location of side cutouts and length of the handguard past the block, one combination may not work for your setup.

I've used SLR, the titanium adjustable, they are supposed to run a bit cleaner as the carbon isn't supposed to stick to titanium as much, we'll see. SLR is a solid company, I love their hand guards too. I would try the superlative arms AGB as well, but maybe not the Syrac.

Not sure what your intended use is, the gemtech Suppressed Bolt seems to work well if that is the problem your solving. I have had good luck with one.

I have two friends that have had very good results with SLR

I have run SLR gas blocks lately and they do well. I like their options from set screw to clamp on, different materials and a good range of internal diameters.

I was able to siezed up one of the Ti SLR blocks on my SBR....no worries though, I pulled it off, stripped it down and cleaned it easily, good to go an hour later.

 

[NHPiper]

Well guys, thanks for all the input. I was leaning towards the superlative, but after seeing what they do venting gas to suppressor covers, I am not sure I will do anything. The rifle runs fairly soft already, it isn't hard to make slow double taps at 200 yards with a 10x scope.

I think SLR has a gas block that big. I've run JP adjustable gas blocks for years on my ar's shooting suppressed off and on. I've since then switched to SLR on all my current rifles and in %100 satisfied so far and SLR blocks seem to be the most serviceable of them all to me. I love JP parts and still run some but I ended up running SLR because all of my hand guards are real Lowe profile and the JP block just don't fit.

Can't go wrong with an SLR.

I use nothing but SLR blocks from my SBRs to my precision gas guns. Makes tuning for suppressors or different loads easy. If the set screw ever gets stuck just put a drop of oil on it and it will be working again in no time.

I'm using the SA on my 6.5 Creedmoor build and it's awesome. Their info says it doesn't get gunked up because of the design and so far it's all good. Easy, solid adjustment and low profile. I got the solid stainless steel and love it.

I use the JP adjustable gas block and like it. Not the easiest to adjust but gets the job done.
