It's all perfect, I ran 4 mags of 5.56 55gr. And 62grn back to back and everything was still in place, i didnt blow off the nose cap which would mean bad alignment and I removed the foam rings from the inside of the can and I bought an adapter from 1/2×28 to 14mm and everything is working perfectly, I'm definitely returning to purchase a 762 silencer and brake, I already bought my adapter.
Thanks sixmm for having outstanding gear.
Oh and for those who don't like the misalignment issue get a heat mirage cover to go over it you will never notice it and you should be fine plus your gonna need it because your still pushing a lot of heat through an aluminum tube.
Now Im going back to the site to buy the 762 version before these stupid tariffs kick in.
Good day.
The bottom of the GM magazine has a button which will block the base pad after you install it. It you need to take the base pad out, it will need a lot of works to do.
They might have shipped me an old version or whatever, but the brightness on my unit is very poor, making it unusable on a sunny day. Otherwise it's a nicely made replica with all the trades and stuff.
Too bad sixmm doesn't want to help me with this issue, customer service seems non-existent, getting into contact is almost impossible.
Everything was very satisfactory and the part firs prefectly
I bought an item from six MM and it was supposed to be tan. Then when I received it, I noticed that it was just a black variant of the same item spray-painted tan at the last second the worst part of all this they used the gold paint and they didn’t let it dry when they put tape on it so it was extremely obvious when I had removed the tape that, when the paint chipped off, it was black. When I tried to return the item the company tried to make it almost impossible to get in contact with them and I did get in contact with them. They would just circle around. Highly recommend this company
