Gas Block Tech Tip: Maintaining Adjustability

- Quick video using a Superlative Arms Adjustable gas block to show how you can prevent the adjustment screws from seizing up do to carbon fouling utilizing Anti-seize compound. This is based off almost 20 years as a diesel/automotive tech and my experience using anti-sieze on a daily basis.
There's no way to guarantee the longevity of this but I recommend every 1000 rounds checking the adjustment screw for adjustability. Once it starts you start feeling tension I'd incorporate a servicing regiment to clean the threads and re-apply anti-seize for maintaining adjustability.
This is someing companies like Triarc Systems will do for customers that request the use of an adjustable gasblock when ordering an upper or complete gun from them.
I just ordered one of these gas blocks. Thanks for the tip, I wouldn't have done this if not for you.
Glad I could help.
Nice tip, thanks.
I bought a couple of cheap gas blocks. Just a adjustment screw with a set screw. Checked after a couple of trips to the range. Both we’re starting to seize up. Read on a AR15 forum to use anti seize. Guy said he has shot two thousands rounds. And they haven’t seized yet. So like you I recently apply some anti seize to mine. I also used heat resistance blue loctite on the set screws that hold the gas block to the rifle.
Nice. I don't use blue because it has a lower melting point. It will come loose eventually unless it's a Precision rig and you don't shoot high volumes of fire. I suggest either Loctite 271 (red high temp) or Rocksett. I personally use Rocksett because it's not affected by heat.
@@airborneivanI believe he meant that he used the high temp blue Loctite. That one is 246, not the more common 242 that you're thinking of. Red Loctite and Blue Loctite actually have the same temperature range. Red just has higher tensile strength. 246 has a higher temperature range than both of them, but tensile strength of regular blue Loctite. On paper, it should be better than red Loctite.
Kroil is much easier apply, after every session. A few drops and then a couple of turn both ways from your normal setting. Stupid quick and easy! Also, Superlative claims if you run it on the exhaust side, rather the restricted side, it won’t seize.
I prefer the anti-sieze route because it's set and forget. One my gas block is set, I don't want to mess around with it unless I have to.
Great video I thought I was the only one who did this
I used copper anti seize instead
Glad to know that others do this. Both types of anti-sieze should work fine.
@@airborneivan Cool, although after firing there was copper anti seize that got sprayed all over the top of the barrel and the muzzle lol
