    Everywhere I looked this was out of stock but then I was lucky enough to find this on a web search. Wow this is nicely built fits perfect and they shipped it quickly. A+ couldn't ask for more! Highly recommend Griffin Armament and will defiantly shop with them again.

    Picked this up for my Sig 716i. Gave me a 90 degree shoulder to mount my suppressor mount to. Maintained alignment with my supressor. Great product, buy with confidence!

    This adapter for sig barrels exceeds expectations. The fitment is perfect. Once seated there is absolutely no movement. A perfect product. Color is cool too!
