Colt MT6400C pinned comp

[WTZC, Inc.]

I have a Colt MT6400C with a pinned on comp. I want to put a Vortex flash hider on it. What do I need to do? I am not a gunsmith (understatement). I was going to keep it NIB but decided I wanted to shoot it. I'm more then willing to send the upper to a real gunsmith and I already have the Vortex. Thanks.

Send it to ADCO.

Send it to ADCO.
+1 Steve at Adco is your best bet. you can also have him change the FSB for one with a bayo lug . :D

Thanks. I thought this site would be full of armchair commandos. Lots of good info. I'm glad I joined. I'll send the upper to ADCO and tell them to make it more like my 6920.
