[ARCHIVED THREAD] - Changing A1 aperature to A2

Posted: 3/15/2006 6:43:17 AM EDT

Maybe I'm slow or something but I'm confused. This being my first build I have read a ton of info on this board to help me along. I have an A1/C7 upper and wanted to change the A1 aperature to an A2 aperature as many recommend. I ordered a new A2 aperature and, Suprise, it doesn't fit. It's not threaded so the existing screw won't fit. ht, Probably

A link if this has been covered or any help would be appreciated

I would like to know more about this too.

A standard A2 aperature should screw in without any problem. I have done this for several of my A1 uppers.

Given the alignment is close enough. The A-2 is wider, not as much windage to zero when mounted in a A-1 upper. If your A-1 shot with the sight centered [best case], The A-2 will work [nicely].
Toss the defect and get a sight with threads. Also, look at the quality of the apperature before mounting. Some are poorly made and will offer poor optical performance.

This blows. hinking.gif I thought it should work. Thanks for the feedback, guess I'll send it back or maybe just do with the A1 sights for a while. Hell, I havn't even fired my new toy yet.

Where did you find an A2 aperature without threads?
