Adjustable gas block?

PSA Products KS-47

PSA Customs sells a great adjustable gas block and it is hard to beat the $50 price. I just put one on an 18" mid-length upper I put together and it has been great. I just clicked it closed and then started opening 2 clicks till it started operating properly, then I opened it 1 more click for ammo variances. Be aware it won’t come with a 7/64 hex key and depending on gas port location under a handguard you may need to order a longer hex key than normal.

BRT EZ Tune gas tubes imo are a better option than adjustable gas blocks. You tell them caliber, barrel length, suppressor use and BRT will send a gas tube with an orifice. It helped my ks47 which was over gassed, recoil was more like a 308 than 7.62x39.
