Seekins Precision .750 Low Profile Select Adjustable Gas Block - SEEK11510065
Out of stock
The addition of a suppressor, dirty conditions or even switching ammo are all factors that can lead to undesirable gas settings on your rifle.
Our patent pending design was initially developed to fulfill an order in our Government programs which required the ability to run suppressed or unsuppressed in the field.
The Select Adjustable Gas Block allows a near infinite initial adjustment using an allen wrench. To begin, simply turn the gas screw in (reducing gas) or out (increasing gas), whichever you require, and finish by attaching the gas switch for tool-less, on the fly adjustments without losing your initial gas setting.
- 40 position fine adjustment
- Tool-less gas selection switch
- Suppressed or unsuppressed
- Melonite coated tool steel
- Gas Block Size: .750 DIA
For Suppressor Use:
- Set the initial gas setting with suppressor on so the bolt locks back on an empty magazine.
- Add ONE click
- Attach the gas switch, and position it all the way to the left (this will be the minimum amount of gas you will need).
- When you want to remove the suppressor simply take it off and rotate the gas switch to the right adding the amount of gas needed to cycle properly un-suppressed.
When you’re ready to re-install your suppressor, rotate the switch back to the left and your good to go.
*Another option is if you are shooting a suppressed .300BLK and want to switch between subsonic and supersonic ammo simply position the gas switch to the left for supersonic and rotate right (to add more gas) for subsonic ammo.

Necessary upgrade
I upgraded a cheap adjustable with 2 nearly inaccessible hex screws with this Seekins unit that has a toggle for on-the-fly gas pressure adjustment. I always got the 2 screws mixed up on the cheaper gas block and had to take my time accessing said screws to adjust the gas. This Seekins model is supreme with only 1 detent gas screw and tactile clicks that can be counted. I have a high end hand rail with slim profile which wouldn’t allow for the long toggle to be mounted so I bought a 6” long 7/64 hex for adjusting the main screw under the muzzle end of the rail. after some thought, I decided to notch my $200 Odin works O2 lite hand guard so that I could install the long toggle to make gas adjustments in the field without requiring tools. I don't regret it: resembles a Noveske switch block setup now. Adjustable gas block is the only way to go with large caliber rifles that are often over gassed. I love this gas block but nearly caused myself some problems with switching out the factory installed short toggle with the factory supplied long toggle due to the pressure exerted on the detent when removing & installing the main gas screw. It can fudge the threads on the screw
