[ARCHIVED THREAD] - UPPER LUG SIZE

Posted: 1/29/2017 1:14:48 PM EDT

Ran across a couple of A1 uppers that appear to have large pin lugs both front & back.Slab side with no FA.
Don't have a camera right now.
N.D estate sale I ran across coming back from a job.
Heading to shop for calipers to check them out.
Should have just bought them & worried about it later.
Where can you find the inserts or what lower will match up?

You would need either an earlier colt lower or you can put a bushing in it.

Those uppers will fit SP1 and Sporter II Colt lowers without modification, or as previously mentioned, any regular lower with an offset bushing.

Yeah at the prices they are I'm not sure I should pull the trigger on these uppers..
Passed them up for now, don't have the lowers & they are overpriced anyway.
thanks for input boy's1
