Okay so here's the deal. I have an extra flat-top upper in the safe and I need to put a barrel on it. I already have a 20" HBAR A2 and a 16" M4 flat-top. I'm thinking of either a 20" Govt. profile barrel, or a M4 profile dissipator. This will be on a post ban lower.
This gun is going to be just for fun, no specific function. Just a general purpose, all around gun.
Thoughts?
