Best rail for 3 Gun on my M&P 15OR?

[Rolex John]

I've had an M&P 15OR for a few years that I put a Daniel Defense Omega rail on (because it was a free floating rail option that didn't require welding or cutting). I want to use the rifle for 3 gun now, and would like one of the long, round and light rails that most 3 gunners use. Any suggestions?

I'm a revolver/1911 handgunner, and a bolt action rifleman. I have finally gotten the urge to acquire a AR15 type rifle. I think I have settled on either the S&W M&P150R or the Colt CSR1518. The Colt comes with a match trigger and match barrel (per the spec sheet). I'm a neophyte when it comes to these rifles, and any help to decide which might be the better buy. It would be used for plinking, possibly some Prairie Dog, and remotely a 200 yard competition. I might add I only recently (since the Paris invasion) decided and it would probably spend most of it's time in the vault standing by for "emergency" use.

I'm thinking you replied to my topic in error, but I'm also looking at the Colt. It may be cheaper for me to modify my M&P, hence I'm wanting to look at rail options.

Rolex John, I put my post in a new post, I hadn't meant to attach to this original. My research shows the S&W and the Colt to be both in the same aprox price range, but the Colt has more advantages, and I have heard very positive thing about Colt quality of late.

While I don't do 3 gun, I do like a light rifle. You might want to take a look at the Evolution Series at www.samson-mfg.com. It comes in Key Mod and their proprietary configuration.

I've just modified my OR with the carbine proprietary system. The only problem was removing the gas block (it's pinned like an ***). I added the Syrac Adjustable Gas Block, which has made the recoil much more manageable and is low profile. You can place the 2 " and 4" additional rails at any point around the handguard.

My other upper is a Bravo Company. I'm waiting for the new adjustable gas block and will install their proprietary 12.5" system.

The Key-Mod system is less proprietary and has more accessories. I chose their proprietary system because it was cheaper.

You don't have to get a new barrel nut. They have a proprietary set of sleeves that fit over the standard barrel nut and lock into place. I cut my delta ring assembly off with a dremel rather than fighting with the barrel nut.

Hope this helps.

Thanks for the info but I was really hoping just to get a light rail.

These are light rails...check out their 3-gun videos as well as their products.

OK I guess I'm not really understanding what they offer versus what I need . I find their website the little confusing .

I'd rather not replace the gas block - I just would like to get A light rail to replace the DD one that I have now. Do they offer something like that?

I just put a AGL Defense rail on my Mid-MOE 16" Smith. Super light and is round with only a short part of rail to hold a front sight. Slots are Magpul MLok type. Rock solid fit and top quality workmanship and finish.
Brownells. Super light very tough aluminum.

If you want a rail that goes beyond your gas block, Daniel Defense and Troy offer options. I have the Troy.

Troy model looks nice but it has a cut out for fixed front site which the optics ready M&P 15 doesn't have.

That certainly looks like a good option - does anyone have any idea what the correct length would be for the M&P 15 OR?

There is no 'correct length' for free float tubes. It's up to you. If you shoot with your off hand fully extended, you'll want a handguard that goes out that far.

Just remember, the longer your handguard, the more weight.

Yes, but the OR carbine has a high gas block that will interfere with most free float handguards, so you'll either need one with a cut out or go to a low profile gas block.

I have a 15" Troy SDMR on my 3-gun rifle. Light weight and the three small rail sections at the front make a perfect grip stop.
