I am looking to put  optics on my RRA Tac entry but still have a desire to use iron sights in conjuntion.  I am looking at ACOG, Aimpoint and EOtech, any advice would be helpful.

You can only use iron sight in conjunction with an Aimpoint or EOTech as they have no magnification.  The ACOG would have to be removed prior to using your open sights.  The EOTech is designed to mount right to a flattop and co-witness with your back up sights with no additional mounts.  In my opinion it is the best sight to achieve what you want to do on that type of weapon (entry gun).

I have a Bushmaster with an A1 upper that I've been thinking of replacing with RRA's UTE tactical upper.  I emailed them to ask about how it would work with an EOTech in conjuntion with the iron sights, hoping, like you seem to be, to be able to use the iron sights as well (as a backup).  Here's my email and their response:


I'm planning on ordering the UTE upper for my rifle and adding an EOTech sight.  Before I do so, since I've never seen anything like your upper before, I'm curious what the sight picture would be like for the iron sights with the EOTech mounted.  Can they see under the EOTech in this configuration, or would they be peeping through the glass of the EOTech? Or would they just not work at all?


And their response:

you will not be able to see the iron sights through the EOtech...

So, take that for what you will.  I'm hoping to get some advice on how to proceed myself.

NOOOOOOO!!!!!  Don't do it!!!

That thing is even WORSE than the "Tactical Carry Handle".  At least with the TCH, if you realize it's not for you, then you can REMOVE it and SELL it!  With the "UTE", you're STUCK with that riser.

It's a full INCH high, which is WAY too much for most optics.  The ONLY quality optic that will work on the UTE and still allow co-witness is the Aimpoint.  All the others will be MUCH too tall and block the irons completely.

Do yourself a favor... Since you want the EOTech, get the regular FLAT TOP upper.  The EOTech will mount directly to that, and co-witness just fine.

Then add any of the BUIS that float your boat, whether folding or fixed, and you can thank me ("us" soon I'm sure) later.

PLEASE don't get it... you WILL be sorry.

Thanks, Onslaught, that's what I wanted to hear.  I'll take your advice.  Anyone have an opinion on a Rock River upper versus a Bushmaster for a regular flattop?

Between the two I'd take Bushmaster - ARMS products are guaranteed to fit Bushmaster flattops (along with Colts and Armlalites).  I don't beleive they extend that guarantee to RRA.

Hmmm... I don't know on that one.  

I believe it's the ARMS throw lever products that have had issues with slight differences in uppers, not the simple cross-slot ones.  

A complete RRA upper from one of the reputable dealers on the EE (ADCO, LegalTransfers) would run you around $90, while a Bushy would be almost TWICE that much.  Coming from one of the two dealers mentioned, they'd make it right if an ARMS product didnt fit, and I'm sure that you could probably get them to test a #40 on your upper before they ship it.

RRA is good quality stuff.  My current AR is a Bushmaster upper and lower with a RRA mid-length barrel, but my next build on the list will be using a RRA upper.   I have every confidence that the ARMS throw lever rings I'll be using will work fine.

Thanks for the reply guys, sounds like great advice.

PS - I shot my RRA Tac Entry for the first time last week, as it is my first AR(military don't count) was not sure what to expect.  SWEETTTTTTTTTTTTTTT!!!!!!!!!!!!!!!!!!. Fired the military 25/300 meter sight in target started low and left and ended up with last 7 rounds in the ring. I M ADDICTED.

Nice shooting.

BTW, I just noticed you're from GA.  Stop by the Georiga Hometown forum sometime.  We'd love to have you join us for a group shoot or something.  (Actually, I just want to shoot the Tac Entry. )
