I am about to place an order on a rail for my M4 A3 Bushmaster Heavy Barreled Carbine. I already have a A.R.M.S. .5 M.O.A. Rear Flip Up sight. Mounted directly in front of that is an Eotech 512. It is the larger Eotech so I have no room left on my current flat top rail. I intend to mount an Eotech 3x magnifier directly behind the Eotech. To do this A.) the rail needs to be continuous and even so I can move the Eotech forward. B.) Fit my gun C.) Be a halfway decent rail.

Rails I am deciding between:
Daniel Defense M4 Rail 7.0 Carbine

LaRue Tactical 7.0 Handguard

I think the LaRue will do what I need it to. If I was sure the Daniel Defense would do the job i would have already ordered one. The LaRue has a couple pluses because it's cheaper and already has a mount for a sling on the rail. I like the low profile sides and think that it may be my best bet.

Please let me know about these rails.
Thanks,

If you want to mount the optic on the rail you may want to look at one that attaches over the upper receiver rail.  Other wise either of those rail systems is good to go.  The SIR type rails are considered better for mounting forward optics to.

I know LMT makes a forged upper that has the railed forend and upper as one solid piece.

Yes it looks like this...



If the LaRue will fir my M4 like this then I think it will work.

Heck, on an HBAR - the TROY MRF-DI would work.

Any DD rail (Omega, M4 Lite) will work great - if continuous upper rail is a requirement, go with that.
TROY MRF-C will also do - simplest to install, requires chopping off the delta ring.
LaRue 7.0 rail will be the nicest looking, but still isn't continuous upper rail.

Thanks for the reply.

I think this is what i am looking for. I am not looking for a continuous rail as I stated... I am looking for one that is level with the upper receivers rail and can allow for bridging of optics.

The LMT MRP is what he was talking about & that is not it.

It's generally not a good idea to bridge the gap like that on a two piece drop in if you expect the optic to hold zero. Even a FF with a continuous top rail can flex but it's better than that set up. Of course, the MRP or VIS would be the optimal set up. Get what works for you though.
