I have owned several and by far am most pleased with Fulton Armory. I have the m-4 configuration with 16" heavy barrell. All the above mentioned are good guns. The only draw back to colt is the lower pinning system is not the same as others. You can not swap uppers as easly. Good luck on decision.

 

we need pics when you pic yours up just so you know.

I'm looking at the new SCAR from FNH 16" barrel with shorter than m-4 capability and it will fire folded. I didn't know remmington makes an ar platform now I must have been snoozing.

 

How the muzzle brake/flash hider is attatched depends on the length of the barrel. If the OAL of the Barrel is shorter than 16" you need to have your muzzle device permently attatched. If your barrel is longer than 16" it can be screwed on.

Fed law rifle barrels must be 16" long or longer.

I agree with rip, build your own, cheaper and more rewarding. Heres a pic of mine. Im using a Spikes Tactical lower
