Need help with BUIS on Eotech 557 with maginifier

[GTF425]

Thanks for the input bro. Im not worried about it fitting under the sight as much as behind the sight. I cant move things any further forward. Is that the same problem your refurring to?
BTW, thought about ditching the magnifier too. Its flawless, I just dont use it that often. Not that I NEED a BUIS, just would like to make the rifle complete.

To this day, I'm still not 100% sure what caused this, but my magnifier fogged up on the inside after about 4 months in Afghanistan. I couldn't use the top half of my FOV. Combined with the short eye relief that was always awkward for me and I finally had the excuse I was looking for to just run the 557 on its own. I eventually put my issued flip-up rear sight back on and kept it flipped up. I never *had* to use my iron sights, but the thought of having to voluntarily flip up a sight post in a 2-way never excited me. Once again, thankfully, my EOTech never failed me. If I could go back and do all of it over again, I'd probably stick with the ACOG I was issued and have just been done with it.

I understand the completing the rifle comment. In my opinion, I'd sell the whole set up and buy an Aimpoint Comp series or a different EOTech. The reticle on the 557 was "fuzzy" in my opinion and the whole BDC aspect of it was wasted on me after I ditched the magnifier. Without running the 4x, I couldn't really distinguish the individual dots and it got in the way when trying to shoot around 300-400 yards. Once again, lesson learned the hard way.

you understand my problem perfectly. I cant shift things any further forward. I guess I need a sight that only requires one rail to attach too and doesnt occupy any space forward of the rail it attaches too.

I don't know why your flat-top upper, Eotech 557 and G23FTS would have different dimensions than my flat-top upper, Eotech 557, and G23FTS. Mine fits fine.

As to FSB's...some of the consumer-oriented rifles use a non F-marked FSB. Being about .04 inch shorter, they usually don't sight in well with the standard iron rear sights on the market. You'd need to add a little taller post to the non F-marked FSB if that's what you have. If you do have that little F, never mind. Any modern rear sight will work just fine.

You may be able to squeeze a GG&G MAD BUIS in that area, but I worry the ARMS lever on the magnifier may not close fully.

Edit: Now that I'm home to check my setup, the lever closes just fine and there's enough clearance.

The Troy only needs one slot. Looks like you have the room you need.
