what is the procedure you use to adjust an adjustable gas block?? i am putting one on my new 12". it was the only one i had sitting around
Are you using an Adj gas block?

Start it wide open and load one round in mag fire and lower gas each round till it doesn't lock back then turn back half turn and fire round if it locks back lock it down and shoot ten rounds if no problems happen your set, if it has a problem unlock the block and open anouther half turn and re lock the block it should be set.
That's how I did it, but have done it the way Explorecaves posted and I didn't care for it because it was a pain to extract the empty case because the bcg didn't get any gas and it didn't allow the bolt to completely unlock, but both ways do work fine.

I agree with Speleocaves. Fully closed tends to stick the bolt in place and makes it difficult to open with no compound leverage of a charge handle.

We don't have clouds around here anything like down in LA though. We were traveling to Shreveport for a conference once and the swarms on the side of the highway looked like they could carry off our car if we swerved into one...Nothing kills the incentive of men faster than a healthy sense of entitlement.

FWIW, I've used SLR Rifleworks Sentry 7 adj. gas blocks (clamp-on) on my Criterion 6.5G 16" and 11.5" SBR (the latter with a Law Tactical folding stock adapter). I've also used them on other builds for myself and others. Mark at PF worked his magic on the Criterions including nitriding them. With the SBR, I use a JP LMOS BC with Mark's 6.5G bolt, a carbine buffer (3oz) and a JP Custom Centerless ground/polished carbine buffer spring. The rationale was to use a lower weight BC because the Law Tactical BC insert itself weighs 2.2 ounces. I have the SLR on click 5 from closed.
An SLR gas block adjustment screw on a .223 Wylde build did freeze. I loosened it but SLR replaced it gratis with a newer design (great CS). So, when servicing the barrel, I click the SLR to fully closed to keep solvent out of the gas block and to also loosen any carbon deposits on the gas block adjustment screw.
The SBR shoots very nicely with quick follow-up shots, i.e., recoil is a bit more than my 16" AR 7.62x39. However, the 6.5G SBR annihilates at CQB and is lethal to at least 600 yards I'm sure. Not bad for a truck gun. Hopefully, port erosion won't be an issue although the nitriding does calm the mind. Lastly, 2A Armament makes a regulated BC as a means, in part, to alleviate port erosion; however, it is incompatible with the Law folder.
