Would I be better off buying a factory Remmy 14" barrel, or just cutting my stock barrel down and have a sight bead put back on?
How far are you planning on shooting?
I picked up a modified choke factory barrel with rifle night sights... wouldn't have it any other way. Other folks would be happy with an open choke and no sights or even a bead. Only you can tell what is important to you.
FYI - The Wilson Combat +1 extension works perfectly with the 14" barrel. If you chop your barrel to flush with the factory magazine cap, it ends up being about 12.5".
Good luck!
