Hey all,
sorry for the noob question but here goes....
I currently have a colt A2 20" HBAR that I carry on duty with me. I'm county so I went with the 20" for rural settings. I've now been reassigned to a metro area and have found myself in the position of clearing buildings with my A2. Don't get me wrong, I can get it done, I'm just tired of humping that heavy bugger around. It currently has a rail system and a Surefire 972 out front...gets a little old..
Can I get a smaller upper and use it on the A2 lower? I'd like to keep the A2 stock as I'm 6'5 and even with my armor on I have no trouble getting a nose to charging handle sight picture. I don't know if this is possible, but what I envision is having two uppers with me - the original 20" HBAR and some type of shorty tac upper so I can switch the two out as the mission requires...
Unfortunately, due to department policy, I'm limited to either Colt or Armalite...nothing else. Has to be iron sights, no optics. First, can I do this with, say, an M4 upper? If it is possible to swap uppers out like that can you guys recommend and upper to use? For what its worth I've been thinking either M4 or A3 tactical for the upper....
Thanks,
Monty
Edit: I'm assuming that an upper would be complete with barrel, handguards etc....is that a correct assumption?
