I'm tossing around either having the barrel threaded for the A2 or having it shortened with the addition of a permanently attached A2 to make the overall length 16" like Fro did. Any pro's or cons with each? How will the chrome lining, velocity, etc be affected?

Also, I'm thinking about adding a FSB with the bayonet lug (purely for cosmetic reasons!); Does ADCO use the taller colt's with the side swivel for replacement?

Thanks for your input!

I use a standard forged FSB/Bayonet lug.
