New BCM 14.5 Build Rail Question:

[TacMedic556]

Ok, this is my second build. The first is a Colt 6920, KNS Pins, VLTOR Club, LaRue mounted Aimpoint M3, Larue BUIS, Magpul MOE fore-end, Tango Down Grip, Enhanced Trigger guard, Smith Vortex Flash Hider, Sprinco Buffer (blue) Spring, Sprinco Extractor Spring. .......Runs Flawless.

Now to new build. 14.5 BCM BFH Mid Length. ....Thats it so far. I am looking for good advice and input on a RAIL setup. LaRue, Daniel Defense, etc. Pros Cons? I want the barrel to be free float. I plan on using a LMT SOPMOD stock, and a LaRue FUG (small) as a reference way out front so as to beer can grip the gun.

Please do not turn this thread into an argument. I am looking for experiences and objective data I can use in this build. Thank you for your time in answering my question.

I really like the Centurion Arms rail and I think it would be a good choice. It is fairly simple to install (removal of the FSB) is not necessary if you cut off the Delta ring and leave the barrel nut in place.

After that it's all cake. It's also pretty light. I would also go with a Vltor A5 ( I believe it works with the 14.5" mid) or I would go standard with an H2 buffer and Springco blue spring.

You may find this thread helpful. You may also find this chart helpful.

IG makes a good point re: the Centurion being relatively easy to install. A similar product would be the Daniel Defense Omega which is even easier to install as it does not require the removal of the delta ring. If you're willing to remove the FSB but don't want to remove the barrel nut (it will still require cutting off the delta ring) and you're interested in a slick-side FF tube you might look at the Apex Tactical.

If you can let us know what you plan to attach to the rail, what makes you want a rail, etc. we can offer better guidance on what rail might best work for you.

The Troy MRF is an easy install as well. Goes on using your factory barrel nut, just cut off the delta ring and spring and your good to go.

Other than cost, I see little to recommend the MRF given the other options available. The MRF is just a heavy rail system with no gain in trade for the added weight. The DD Omega and Centurion are both <13 oz. for the 9.0 while the MRF is ~16 oz. That's a lot of added weight over the support hand for no measurable gain in any other category.

I agree with rob. The MRF is too heavy. If one were to go that route in temrs of mounting method, the Centurion would be the better option. If you dont want to go about cutting off the handguard cap and delta ring assembly, get the DD Omega.

What will your main use of this gun be? Also, what do you plan on mounting on the rails? Below is just my experience and opinion based on a general use rifle used for classes, drills and home defense or duty use. Also, I only recommend rails if you have a few things mounted like a light, vert grip and possibly a laser system. If you're mounting nothing but a light, I would usually suggest a MOE.

I am very interested in the Centurion rails. They're lightweight, solid and easy to install. I've always liked Daniel Defense rails as they're solid and sturdy. I'm trading one of my SR15 uppers now possibly for a MK18 style LMT upper with a DD rail. I've owned a couple before and just prefer them to everything else I've owned.

Of your listed options, and this is just personal choice after owing both LaRue and DD, I'd lean towards the DD, preferably the Lite rail in most cases. I don't have experience withthe Omega but it appears to be very easy to work with.

It sounds like your upper has the front sight base, and like IG suggested, I'd take a look at the Centurion FSP midlength 12" (or 12.5", I don't remember). It's one I'm very interested in as it allows use of the front sight block and still offers a lot of real estate on the sides and bottom. DD offers a similar rail but Centurion's looks promising and the front seems to have a nice contour.

Sorry for this quick break from the topic -ROB, I emailed you a linked to two forums where I posted the links back here to the new chart's thread. Just figured I'd mention it here since your inbox is full and I wanted to be sure you got it. Thanks, and sorry OP.

The new Samson Evolution looks like a good weight conscious option. I was looking into that or a DD. It looks easy to install but I do not have first hand knowledge of that.

[TacMedic556]

Thank you all for the feedback. Great stuff. I will be sorting through it and looking at all of them.

To answer the common question of what will be on it:

LaRue FUG (grip)
Surefire light.
Sling swivel mount

So far I really like the sound of the DD Omega. I haven't seen as much on here about LaRue as I would expect. Can anyone give me some insights into the LaRue rails? I had initially counted on going with the LaRue. Thanks again.
