I have had a few different flip sights, I have felt a few other flips sights and every single one (except the GG&G MAD REAR BUIS) has play in it. I bought GG&G's front flip sight to match it but it does not lock the same way and it has some play which obviously leads to long range inaccuracy I am contimplating switching to a standard FSB so that I can have the reliable accuracy that a front sight should have but I want to run a scope that would conflict with that. *Question. Who makes a replacement FSB with a flip up sight built in it that is actually SOLID as in there is absolutely 0 play in it. I'm switching to plastic hg so please dont suggest rail mounted versions. Thanks in Advance!!! -Sam Pic of my gun right now, Magpul moe hand guard is in the mail so its going look alot different soon. That LWRC ARM-R rail thats on it in the pic was horrible. The design was flawed so that the free float clamp would start to come loose after aggressive use. I've learned a valuable lesson. The more simple you keep things the better it will perform. Parts that look neat do about that and that only; look neat.
