Well, I like the ARMS BUIS. I have ot hsd any problems with it changing POI, but I could understand how it could happen. Along the same lines on the EOTech, a fews weeks ago somebody posted on here, why have a flat top with a front sight, so I thought, good point. SOOOOO ... I got my flat top out and ordered a YHM folding front sight on mine , and really liked it, It made my EOTech so much easier to use. Nothing in the way. It is hard to imagine how much better the Halo-thingy works till you try it with out the front sight in the way. a whole lot quicker. Really nice.
BUT I wanted to have 2 front rails, so I ordered the 3 rail add on.
It would not fit around the gas block. So I took it off and got a gas block that had 4 rails on it,
then got a YHM fold down front site.
I have a grren laser on the bottom rail, a M3 Streamlight on the left rail, where I can use my thumb to turn it on and off. I tried handguards with rails, but did not like the way they felt, even with the covers. I like this set up the best of all that I have tried. This has worked really well for me. I have been meaning to thank the guy who asked the question to start with.
