Easy to install, Though I had to loosen the barrel retaining screw to get it in properly. I now have tightened the retaining screw so the adapter doesn't come out and I can just unscrew the barrel like normal. Only odd thing is that the bolt is kinda wearing down the area of the adapter, the bronze color of the bolt is rubbing off on the adapter, doesn't seem to cause an issue though.
now i can use any barrel i want too thanks to rockstartactical
I have had this adapter for almost a year now and it is holding strong! I use it to connect my LAPCO FSR Barrel, Hammer Head barrels and other A5 threaded barrels to my T15. The only thing I can say is that without this adapter, my platform would be boring and unadaptable to my styles of play. This is a beautiful piece of machined aluminum and it holds strong to this day!
