| I have a RRA A4 9mm on order and was wondering will any BUIS work or is there special ones designed for 9mm? I will at some point put a reddot on it that is why I am looking for which BUIS to buy. Thanks in advance. |
| Im pretty sure you can get away w/ putting any BUIS on it. Something you might want to think about before you buy is what BUIS/scope/optics will co-witness if you want to go that route or if you are primarily using a red dot and you want the BUIS folded down and out of the way. I have a LMT fixed rear/Eotech/standard A2 sight on my 9mm and it works great. |

+1 Try to get your red dot sight first. Either the S.P.O.T. Mark III, Aimpoint, and EOTech red dot sights are fine. I would just like to add to the list you should take a look at are GG&G BUIS. I also have a RRA A4 9mm complete carbine that I built myself with Hahn mag block. The BIG BAD BUIS FAQ tacked thread link |
