Adjust Gas Pressure For Different Loads

7075 Aircraft Grade Alloy gas block replaces factory part using simple tools and helps you fine tune the gas pressure on your Ruger® Mini-14® or Mini Thirty®. Let’s you adjust the distance brass flies, reduce battering of the op-rod, and protect optics from excess shock. Improves accuracy by reducing the internal harmonics of the op-rod contacting the receiver during high speed cycling. Adjust from no-cycling for single-shot operation, to wide-open shooting. This Gen 4 gas block is light weight yet very durable and strong. The Gen 4 also features a newly designed positive click adjustment knob so it cannot move out of adjustment. Comes with Sling swivel stud that fit most swivels.
