Go with the URX. It's a beautiful fit and great light rail. They're stupid simple to install...one of the easiest rails I've ever done. If you can't borrow a wrench buy one and then sell it. I believe member UncleMoak just make a run of his aftermarket wrenches so look him up for a cheaper alternative. If you don't have something like a PRI block to align the rail with the upper receiver before tightening the barrel nut you can use a solid scope mount to get the same result (that's how I installed my first URX).

BCM KMR I sold my Colt 6933 upper and replaced it with a BCM BFH 11.5 upper with a KMR rail. Absolutely love it! It's so lightweight and looks like it's a super easy install. This is my new favorite rail.

BCM KMR, do it.. youll fall in love..
this is my 10.5" with a 9"kmr, yours will look the same just an inch longer, since you have a 11.5" and will need a 10"KMR

I really like the look of the URX II MID that CMS posted better than any of the others on a 11.5 build. I will have to see about borrowing/buying a wrench.

Alan Another feature I enjoy is the heat shield. Most lightweight rails these days lack any form of heat shield, and after long strings of fire become uncomfortable to handle without decent gloves. There are plenty of good options out there...choose one that fills your requirements. The only down side to any of KAC's URX line is the requirement to buy a wrench, where other companies often include one. Once you get past that hurtle it's easy. Your URX collection will grow quickly. Best of luck! |

The Centurion IS the best IMO that uses the standard barrel nut.

And if you want something thinner there's always the URX 3.1 midlength. Only downside is that it does not come with an integrated front sight, which is a great feature and adds value to the URX 2 and 3 rails (saves you $100+ on a front BUIS....and offsets the cost of the wrench anyways). Unfortunately, AFAIK, KAC never made a mid length URX 3. It would have been my ideal rail.

I was in the exact same boat...rifle is built, suppressor is in jail. I was either going to build with a URX and send the parts to Ayan at boltcarrier for proper assembly, or go lighter and pick up an 11.5 BCM with the KMR. I don't think it is possible to go wrong with either choice, so I went with the cheaper option which was BCM with free bcg.

Alan Do yourself a favor and go on more than 'looks'. See if you can get hands on one before you decide. The URXii is heavy as hell by today's standards and I personally just ditched one for a 10" KMR. Don't regret it for a second. before

My DD RIS II rail is nice. It is very light weight, strong, and narrow. I have fairly small hands and I can get a comfortable grip around it with the ladder rail covers and a AFG.

10" KMR. Have JUST enough room to mount the G5 or HVT
ETA: After you use the thick shim.

There's no reason to buy any handguard other than the KMR right now in my opinion.
I've had two Troy Alpha rails and one KMR. I just bought a second KMR to replace my 9" Alpha and sell it. |

It's about more than just Keymod. The KMR is crazy light, feels amazing in the hand, is very narrow, has an octagonal profile instead of picatinny rails which are square, has a barrel nut that doesn't require timing, and anti-rotation without requiring proprietary modifications to the upper (e.g. the NSR.) Plus, it's Keymod. Directly attaching accessories to the handguard without a need for mounting interfaces is awesome. I have a BCM sling mount and VFG on mine. They both mount directly and are very low profile. I'm completely sold on Keymod, and see it as a huge improvement over picatinny rails. Of course picatinny has its place and won't go away, but Keymod is an excellent addition. If you haven't tried a BCM upper with their new barrel profiles and the KMR handguard, you're missing out. Military Morons has a great write-up about the combo. |

Keymod gets my favor at the moment I agree about not retrofitting them in general, I had a specific reason to upgrade otherwise I would have just stuck with the Alpha. A side benefit is that my rifle will drop several ounces in the process. Alpha to KMR. LaRue FUG to BCM Keymod short grip. Two sections of metal rail to one section of plastic rail. It should be noticeably lighter. |

I've been looking around and do liket the keymod rails. I may try a 10" KMR for this build.
I like the Noveske NSR rails as well and they have 11" but I'm not sure it would work with a saker suppressor. Probably not enough clearance? |

I have everything figured out for my next build. 11.5 SBR that will be suppressed with a saker 7.62. I can't figure out what handguard to go with though so I'm posting this for some direction or pics. I had settled on the KAC URXII MID but just noticed it takes a special tool to install and if not done right, you may have issues. I guess I'm left with a 10.0 rail for this build. I've heard Centurion 10.0 is good as well as DD 10.0. Anyone have any pics or personal preferences for any rails. I like the longer, closer to flush look. Thanks! Here's my BCM 11.5 with Saker mount

there are hundreds of choices. Probably need to narrow it down to what you want it to do.
What features are important? Function should determine what you buy, not whats popular, cool, new, etc... Unless its a safe queen meant to just look pretty in which case put some cool stickers on it! Weight? Dimensions? ie small or large grip, circle, square, oval, rectangle quad rail? keyhole rail? are you mounting accessories like lights or lasers? do you want it full length so you can grab at any position are keeping it short as possible to keep your hand away from suppressor and keep weight down. |

If you happen to be around Pittsburgh I have a KAC URX wrench and a set of YHM picatinny vice jaws I'd let you borrow for the day or whatever, I used them both to install my URX II mid a few weeks ago and now they're just sitting around.
