I want to equip my two ARs (Colt 6920LE and Colt CRP-18) with a silencer. I have never dealt with silencing an AR and have questions. I see they're are many style of mounts for the Saker, which ones would be recommended to put on my Colt's to host the Saker. Also, are they difficult to install? From reviewing past post it looks like the Saker 7.62 is the most chosen of all new silencers out there for ARs, if I am mistaken please give me some advice. I really like my Spectra II made by Silencerco, so I'm leaning towards the Saker.
