Reviews & Ratings for Ultradyne Quantum Gas Block — 2 reviews — Page 1

Construction is pretty good but the tuning click positions are not as well defined or audible as the Superlative Arms adjustable gas block which I typically use on all my builds. I do like the locking set screw on the Ultradyne gas block, though. It is a nice feature, especially when compared to the was it was implemented on Odin works Gas block. The Ultradyne has a salt nitride finish both on the outside *and the inside* of the gas block's tube shaft which limits travel of the gas tube into the block. I found that NONE (three different brands) of my gas tubes would fit into this Gas lock before I spent about 20 minutes working the tube into the gas block. I've never had that issue before but after some twisting and tapping, it finally moved the 1 millimeter I needed to drive my pin home. Performance has been great, it works and looks good and while yes, I'd purchase it again, the next time it will not be my first choice.

Adjustable gas block it's fantastic easy to install easy to adjust
