This is a std set up for adding an ambi safety. It is clean and functional. I do not use ambi safeties on other than my pistol AR. It is a close in, in your face piece and the ambi safety allows manipulation easier/faster in tight quarters, barricades, indoors etc.., using support arm, etc., My other AR's run stock safeties and I like it that way. I am not a gear junkie and I do not think that I can out engineer the designers etc...I make only changes that are proven and have true value in performance and usage...not cosmetics and cool factor.
Great buy !
This is a Must Have uprate! Superior Quality at a Fair & modest price. Do Yourself & your firearm a favor. Installs in less than 10 Min.
Worked on my billet AR-15 build but was to tight on my AR-10 build. Feels solid and does the job may buy again for more builds.
