who makes the best M4gery and how much do they usually run.  is the 16in barrel best or a 14in.  thanks

If you are talking pre-ban, I will go with Colt. 16" barrel is the legal lenght for civilian own. If you want to go with class III, then I still go with Colt and the 14" barrel.

I have to toss my hat in for Bushmaster (or at least be the first to do so).  They had the Military contract to suply M4's before (I've heard} Colt sued and cost them the contract.  an M4 is a 14.5 barrel, but since as a civilian you must have at least a 16 inch barrel, you can go with either the 14.5 barrel with a supressor/compensator (depending on pre/postban) permanently tacted on, or a full 16 inch barrel and the added velocity that the 1.5 inchs give.

Troy, you came through even when you didnt mean to! for about a week i have been trying to find out if the Gemtech bi-lock was long enough to make a 14.5 legal. THANKS!
