    Excellent Fit and Finish

    Fit my Saker 556K perfectly. Reduces the overall length and weight slightly. Mounted length is slightly shorter too compared to the ASR.

    Plan A vs ASR

    Published by Ryan Burpo on 7th Jan 2020

    I purchased this and several muzzle devices to replace my ASR devices. The reason for the change was primarily to save weight. I had no problems with the ASR system, but I wanted to try to lighten my firearms where I could. The ASR system is/was about 1/4# heavier than the Plan A system with the single port brake. It also shortened my Saker 5.56K by 1cm. Overall I’m happy with the result. I’ve shot about 100 rounds since the switch and the Plan A is working as advertised. Great option for those looking to make a change.

    Nice way to adapt Saker to taper mount

    Published by MP on 10th Sep 2019

    Bought both a Plan A Saker and Plan A Omega to mount my various SiCo suppressors to the wonderful Griffin taper mount brakes. I like the taper mount so much, I am going to mount minimalist brakes to a couple of my DT hunting rifles for use with both my SiCo and Griffin cans. I like the taper mount over direct thread for the lock-up and thread protection.

    Best mount for the money

    Published by Drew L on 17th Jan 2019

    Ive been waiting for awhile to see this when Griffin was teasing it. The other mount options for the silencerco cans were pretty expensive. I was blown away to see the quality griffin put into this for the money. Best option on the market for value and I get full access to the Griffin muzzle device line. Home run Griffin!
