(and remind a veteran again why one needs a free float for a weapon that has a range of 300 yrds point and 600 area?) sorry to get into a huff over this but why spend so much money on something he doesn't need? a relatively inexpensive railed or flip up gas block is a way cheaper fix than a free float quad rail. i agree about him needing a quad, but unless he gets a quad that extends over his gas block, his front sight will STILL be too far back. seems everyone is projecting what they want for their own rifles or what they have on their rifles without actually thinkin about this man's problem. get a front sight base or a clamp on gas block with a flip up. the fact of the matter is is that his front sight is way too high and too far back. WHY? what the hell does this have to do with the front sight. I have one on my LR-308, and I am VERY impressed with it.Įveryone is telling you to get a free float quad rail. If you want to get a sturdy slip-on set-screw gas block, get a PRI low profile gas block. While I don't really care for clamp on, I will admit that mine has worked with no issues for two years. You could shave it down, or you could get a low-profile gas block. I have a Dremel, but knowing my retarded ass, I'd go overboard, so I'll probably avoid that route. Easy enough for a moron like me to install?ĪrmedSuspect mentioned shaving down the gas block, maybe. Sounds like free float is better than non free float. I have YHM rail-mount height flip-up sights on my forearm, and they have done fine for the last couple of years. I honestly find that the diameter is a little thick, but it will do the job for an affordable price. It has worked well for the last couple years. I've got a YHM lightweight rifle-lenght rail on my M4gery.

I'll just keep looking at these websites y'all suggested. I'd like to keep the MBUS, so quad rail it is. Or could I still make this set-up work (with some kind of bayonet stud mounted light mount perhaps) and save the money? This would give me increased sight radius between my iron sights (which now is only about 12'), hopefully solve the 'wiggle' problem with the handguard, and let me put an offset light mount on one of the side rails. I can grab the VFG and rotate the handguard (plus front sight) +/- 1/16' from vertical.Īdd this to the fact that I'd like some way to mount the Surefire G2 I just bought, and I'm thinking I need to spring for an extended, 2 piece carbine length handguard- something like this from MI (for example): Also, there's about 1/16' play in the whole assembly- i.e. I haven't zeroed it yet, but this doesn't give me much confidence. There is no front sight post, so in order to mount the front BUIS, I bought a length of rail and screwed it directly onto the stock handguard, then mounted the Magpul BUIS to it.Īs you can see, the plane of the front sight is higher than that of the rear sight. I have this flat top Bushmaster (pictured).
