So, I’m building an A2 “clone”, except that I’m making it how I think it should have been. That means lightweight barrel and A1 length CS stock.
Anyway, one of the things I’m considering is using A4 sight guts (6/3 0-600 yards) instead of the optimistic A2 (8/3 0-800 yards) sights.
I currently have a Colt A2 upper, and will be getting a Colt A4 carry handle.
Will I be able to swap the sights themselves between the two? Are they compatible?
Also, my lower happens to be an old Colt .170" FCG large pin lower, and the hammer is notched. Does anyone still sell a rounded (not notched) .170" Hammer?
Why are you worried about the Type 2 hammer? Is it a functional thing? Or authentic appearance? As long as you have a real 16 carrier, the Type 2 hammer will be fine.
Not worried, I just don’t like notched hammers. They feel gritty when cycling the bolt, and remind me of the evil black rifle ban of '94. So I just prefer standard rounded hammers whenever possible.
And yes, I am using a standard M16 carrier.
I had an ALG QMS set aside for this build, until I got the lower and discovered later that it was a large pin… Go figure.
Thank you very much for the info and picture.
So I definitely won’t be doing that with the carry handle, but would still consider doing the other way around and putting the 6/3 guts into the A2 upper. Think that would work well?
I can’t see myself shooting any farther than 500-600 with iron sights… Can barely even see the target!
With an ACOG I’ve shot out to 800, however, with great success.
As far as the trigger, geissele does indeed make one… It’s a little pricier than I’m willing to spend right now, however.
