    Excellent Product

    Excellent machining and fit. The only thing I would say is that if they were to shorten the front of the outside collar and rear of the adapter it would work great with VG6 Epsilons and Gammas.

    A2 Adapter 1.375x24

    Published by SS on 7th Jul 2021

    I've been looking for this solution for years. Shipping was faster than expected. Threaded onto Silencerco Omega and worked perfectly. At $100 per proprietary muzzle device do it this way and save money if you have more than one you want to mount to. Wish I had it 5 years ago. Only thing I would change is add knurling to the cap. Well done!

    A2 adapter mount

    Published by Bryan Corbitt on 9th Dec 2020

    Works like a charm and fits 22 caliber and 30 caliber mil-spec birdcage flash hiders like a glove. When I get more rifle cans I will get more of these adapters.

    I have a lot of rifles with A2's on them and now I don't have to replace them to run my Vox. Fits the VG6 Gamma on my BCM like it was made just for it.
