Little strange to have it tuned perfectly when opened to the prescribed starting point of 4 1/2 full turns only to go beyond that to get into the actual bleed off feature. Took a little research into the block to understand what's going on with that aspect of its function. It does however make for a soft shooting gasser in my case. So much so that I'm considering changing out on several of my rifles.On Superlative Arms Adjustable Gas Block Bleed Off (Solid) - MeloniteJJustin i.Verified Buyer5.0 star rating07/01/25LOVE EM'Review by Justin i. on 1 Jul 2025 review stating LOVE EM'I've always wanted one of these and I finally got one.
