Details

The Seekins Precision Adjustable Gas Block is a low-profile precision machined upgrade for your AR-15. A finely tuned gas system can significantly reduce recoil, allowing for faster follow up shots, maintaining shot by shot target acquisition, and improving the overall reliability of the platform.

This side-adjusting set screw allows the user to readily change gas pressure, in some cases, directly through the hand guard. Lock the desired setting in place with the front facing nitrided set screw.

Steel construction and a durable Melonite finish help reduce erosion of the gas block allowing for a longer service life.

Features:
  • Set screw style mounting
  • Salt bath nitride finish
  • Overall height: 1.37"
  • Width: 0.94"
  • .750" gas seat diameter
  • Just 1.8 oz

Outstanding

by -

This gas block is an outstanding value for the money. It offers very precise adjusment. As far as fitment with various hand guards, if you have an opening in your current handguard that exposes the rearward/upward most half of your current gas block, you will be able to easily access the adjustment screw.

Check your system to see if you need a side adj, or front adj gas block.

I bought mine last fall. The adjustment screw was on the side, locking screw up front. Sounds like what folks are calling the "old style" now. Mine worked fine in a carbine length system with an Odin Works hand guard, you can reach the adjustment screw from the side. If you have a 15 inch hand guard, reaching the lock screw from the front might be an issue. I made an extension for my Allen wrench. I just swapped the hand guard to a Diamond head, and I can not reach the side set screw through the new hand guard. There are pros and cons to every set up. Just check your system to see if a side adjustment, or front adjustment, screw will work better for you. I am very happy with the build quality of the gas block.

Seekins at its finest

New easy adjust model now!

by

I recently purchased a complete seekins upper chambered in the .300 AAC blk. And it came with this adjustable gas block already installed. I have purchased many items from PA with great success and lightning fast shipping...but this particular upper came from a different vendor. I just wanted to clarify that this adj.GB now comes with the set screw facing towards the muzzle for easier setting and releasing of the (lock down) set screw. Besides that everything looks the same. Hope this helps some of you to make an informed decision. <br><br>PS. Even if you get an older model with the set screw on the rear of the device it should work fine unless your running a supper heavy barrle, Then it will be a little bit more of a chore to operate but still very doable. Thanks PA for all you do for the community!

Price-Checking before ordering a second for next year's SBR and saw....

I was just price-checking before ordering a second for next year's SBR and saw a few bad reviews (seem outdated).:I just bought on for a 16" ARP 6.8 spc middy build that I opened up the gas port large enough to cycle OTC ammo. Once opened I used this gem to back the gas down to tame recoil on the hotter hunting loads. My cheaper $8 import nonadjustable LP gas block leaked a tad w/the bigger port but this one was flawless. Sometimes a gas block and barrel can be a bit loose depending on the stacked tolerances. :The one I bought was in 2016 August was it? NOTE: mine had the gas screw to the side as the old style and the setscrew to the FRONT. It was a thing of beauty now I can shoot it all out of the 16" middy and were I to can it I don't have to eat gas. :One note I used a Midwest Industries SSM style keymod generic clone 15" handguard. These are super small 10oz type free-floats and I did a bit of relief to ensure it floated. I didn't mount one of the Noveske NSR style units I use but they seem to be a scoatch more roomy under the guard. :I can't say which style old or new you will get if you order but I like the redesign.

Leaks all over

by

As for Primary Armas service this guys are prompt in the shipping and communication. The gas block leaks through the adjustment screw the the set screw and the gas tube port. Measuring with a gas flow gauge it looses 23% of the input presure. Using Loctite doesn't help. I had to stop the leaks using high temperature silicone sealant. No very good as when screwing in or out the adjustment I may bring some cured silicone into the gas tube and defeat all purpose. I have other Seekins products and this one doesn't look like it is of their making. Not happy.

Nice for the price

by

They must have moved the brass screw as mine is in the front. I can adjust it with the handguard on but need a long allen key for the front screw. My handguard is a UTG pro slim and I can access the adjustment screw from the side.

Gas Block

by

This is my first adjustable gas block I've gotten and I love it! Definitely gonna start putting these on all my builds!

Beware of the lock screw location!

by

The brass lock screw is on the rear of the block and the adjustment screw is on the side. They may not be accessible on some handguards without disassembly. And the brass set screw came loose after shooting 100 rounds. It is nice to tune the gas system instead of the buffers and springs.

Fast good price

Tittle says it all fast shipping and good piece on a part that was hard to find.

Nice block

Not very easy to adjust after installation. Wish the adjustment setscrew was on the other end (towards muzzle), but fit well.

Very good fit on my Seekins 18" barrel, has set screws to hold in place. Very nice finish

Recoil reduction

by

Purchased this for my 18" rifle-length gas 3 gun AR. While I would prefer a set-screw to be on the front, my free float tube is very easy to remove and reattach. Combining this with a low mass bcg, emptying out the carbine buffer, and making reduced power loads I do not come off of target during rapid fire.

Very Poorly Designed

by

The adjustment screws are on the wrong side of the gas block! They're on the back side where the gas tube exits! Most people purchase a low-profile gas block for free-float hand guards where the gas block is partially or completely covered by the guard. If it's even partially covered, you can't make adjustments to the gas block without removing your hand guard! The adjustment screws should be opposite the gas tube so you can reach in the open end of the free float guard to make field adjustments. Nice styling and finish, but horrible design! Don't buy it unless your hand guard is shorter than your gas tube.

Great product

by

The gas block has an additional brass screw that helps lock down the adjustment screw.I love how compact it is!

Great service!

I was so happy when I found that Primary Arms actually had the gas block in stock. What really amazed me was how fast I got it.

Perfect, simple, and exactly what I wanted.

by

Wow is all I can say. I have been a fan of Seekins since they introduced there products. Everything they make is innovative and beautiful. The gas block is easy to use and adjust. It is ultra low profile and worked perfect on my 7.62x39 Armalite upper. Thanks Seekins and Primary.

Nice product and great service from PA

by

I'd never ordered from PA before but will again if the opportunity arises. Delivery was prompt, especially given the general frenzy at the time my order was made.The gas block is well-engineered and well-made as you'd expect from Seekins. I did find out, however, that with some barrels, the brass set screw may be obscured. The idea behind using brass is that it will still allow a few on-rifle adjustments. But depending on the barrel, you may need to loosen and remove the gas block to retighten the set screw.

Excellent...

by

The gas block slid right on and adjustments were a piece 'o cake. Highly recommended.

Nice gas block, no matter the price.

by

I'm not used to seeing inexpensive Seekins anything, but this gas block is well below the price of its competitors, yet retains the well done machining and high quality one expects of Seekins. I'll be buying more of these.
