Hmm, I still have all my original allen wrenches and I have installed and taken off my of the prototype flash hiders. Make sure you are using the right one. I'm thinking on the next batch to go to a #8 setscrew. I already did this on some of the ones for the 4095.Bushman98
Will that be Paypal?
I would ask one thing. Bigger setscrew hole.
I love my flash hider in all ways but went through 2 hex head wrenches to tighten the small set screw that the hole allows.
I could go for a full length with forward post, I was wanting to put a laser inside the ATI stock but lasers stink in practice. Besides I'll have my red dot on the picatinny.
So when do you want the funds?
