Hi everybody, and thank you for taking the time to read my thread!
I'm new here, and a proud owner of an AR15 configured as an M4. I spent quite a bit of time getting it just the way I want it, but have just come across what might be a problem.
I pretty much customized it from scratch. It is a Smith and Wesson M&P 15 lower, a Hogue grip, a Rock River Arms telescoping stock, a CMMG 14.5" upper with welded phantom flash suppressor, a Tapco T6 buttpad, a Fire Force 3 point sling, an EOTech 512 holographic weapons system, and a Matech flip up BUIS.
My (potential) problem is that I didn't realize how badly I was limiting myself by getting the 14.5" barrel with the welded flash suppressor. I did some research, but not enough. CMMG was a local company for me (I'm from Missouri), the 1:7 twist chrome lined barrel seemed good, and it just plain looked cool.
It has a pretty basic carbine length handguard. When I place my EOTech 512 sight on the picatinny rail, if I leave enough room behind it for the BUIS and to access the buttons on the EOTech, the front of the EOTech extends slightly over the top of the handguard. I expected that. What I didn't expect is that the handguard sits *very* slightly higher than the sight, causing a *very* slight incline.
Will this throw off my sight picture, or does the holograph somehow compensate? Ideally I would just replace the handguard with a quad rail that sits a bit lower, but can this be done (if I find one the exact same length and use the same gas block from my front sight) without cutting off the flash suppressor? The handguard appears to be two pieces so I'm wondering if they can just come apart once the front sight is removed and a new one "dropped in". My only other options are to move the EOTech back a bit and not use the BUIS, or buy a new upper I suppose. Any suggestions, or is it ok as is?
I know I can adjust the elevation on the EOTech of course to compensate, but will the slight incline be an issue with maintaining zero at varying distances?
And just out of curiosity, even if that is the case, do I have any options to replace the hand guard?
