M&P 15T Replacement

I personally prefer Keymod but both work and both have strong industry support.

I am new to AR15s and really to guns in general, so I recently found a video discussing pros/cons between MLok and Keymod. They suggested that one is likely to overcome the other in market share, and that since MLok has been adopted by companies such as Magpul, it is more likely to succeed. So if that's accurate, I'm glad S&W is a adopting it here. The additional length(I think I counted an extra 6 rail positions vs the quad rail) looks better to me, and I would assume makes shooting easier when you can grip the handguard further out. Really excited to see this in person! :)

Found this website today. No idea if it's a reliable note, but it suggests these might be available in the next few days.

Honestly I think both will survive. Keymod was developed by VLTOR and Noveske. Companies like BCM, Daniel Defense, Aero and others have adopted Keymod.

Magpul developed the Mlok which accounts for the higher sales numbers. Even novice AR15 shooters are aware of the Magpul brand name.

I didn't realize MLok was a Magpul product, my mistake.

The other reasons I heard for why Keymod might not last were that the machinery to make it is more complex and expensive, and that the design itself requires a license to duplicate. But with names like BCM and DD behind it as you said, and apparently a good aftermarket presence, it makes sense that Keymod probably isnt going away either.
 
Everyone prefers their choice of handguard for different reasons- when I told a shooting buddy I was putting a free-floating quad rail on one of my AR's, he told me don't do it- they were obsolete. I still did, and am very happy with the choice I made. Sure, switching to a keymod hand guard will appeal to many, but S&W needs to ask themselves why the M&P-15T was so popular in the first place- it wasn't just the 1:8 twist. Many people want the quad rail and add it to the ARs all the time.

Speaking of Magpul, I wish S&W would have offered the M&P-15T with a better stock and grip- I'm putting a CTR stock and MOE+ grip on my 15T as soon as possible. Those two items make any AR more comfortable to shoot, at least for me.

I agree. I think that is why OEM models are as popular as they are.

I have two 15Ts. One is completely stock and my girlfriend uses it. The only modification I've done to the other one is a CTR stock and MOE pistol grip. I would have went with a MOE+ but couldn't find it in Foliage Green.

I do have a CTR , MOE+ grip as well as a MOE for end on another AR15 carbine I first bought years ago.

All three have a Magpul ASAP..

Obviously I do like Magpul stuff.

I finally got my M&P-15T home last night (10 day wait in CA gun jail- 5:10 pm and not a minute earlier). The 15T's Melonite barrel does have a nice finish on it, but as expected, the stock and grip are fill and are basic spare-parts items.

I'm betting the 15T will be downgraded with the 1:9 twist barrel found on the Sport II.

Quad rails were popular, but that is changing. Many folks seem to want what the military uses, and with the Army adopting MLok for a rifle I think the quad rails days are numbered. Factor in that with MLok or Keymod both allow you to attach gizmos to your rifle but do not have the cheese grater effect of the quad rail, and you can see that these are the future.

I'll take that bet! I would be very surprised if S&W changed the barrel on the 15T. The 15T is one of their upper-middle range rifles. If they change the barrel to match the Sport 2, then they would lose sales due to folks just buying the Sport 2 and adding the free float rail themselves.

They kept that 1:8 twist, 5R barrel on the 15T so that it would be considered as a premium rifle over the Sport. Product differentiation.

While I have no plans nor want to change the quad rail on my rifle, the M-LOK and Keymod are definitely the way to go I think for most applications. Smaller in diameter, lower profile mounting, lighter and they got to be cheaper to make than cutting out a quad rail, ya think?

I have no idea how these are made and how much they cost. Another reason is the 2 new ones are much easier on the hands. Quad rails need rail covers if you are not wearing gloves.
 
Lighter, slimmer and with no sharp edges, not sure why anyone would do with a quad rail over an m-lok/keymod handguard at this point, but horses for courses as they say.

It's 2017 and I see the gun stores I patronize have the M&P-15T in stock- I would imagine any LGS could get them too. The keymod and M-Lok guys are always quick to bash any rifle with a quad rail, but it works for me and I don't have to mess around with screws, etc just to mount covers or accessories.

As for the rails being "sharp", put some gloves on those soft hands and deal with it. I shot my M&P-15T before I got my Magpul XTM rail covers and it wasn't that bad. Truth be told I put the covers on more for looks.

Looks to be largely unchanged, other than the handguard and flash hider.

The handguard and flash suppressor are new but it also looks like the new T (2017) also has a mid-length gas system. Doesn't the original (pre 17) have a carbine length?

Yes, the quad rail T models have been carbine length gas. Mid length gas is new with the M-Lok 15T.
 
The first things I did with my 15T was add a ACS stock and a geissele SSA-E trigger. Stock trigger and but stock I really didn't like.

I can believe that. For an "upgraded" gun both those parts on the S&W 15T are pretty basic. I assume they use the same parts across all models, except for the VTAC, in order to create economy of scale.
 
the only rifling twist is 1/12 was good enough for us in the 1960's and is the best for 55 grain slugs and works great in my A1's:)

I too wish S&W would add those features to the M&P15T. I'll go one farther and say they should also put BCM GunFighter charging handles on the M&P15T.

I added all three upgrades to both my M&P15T and my Sport 1. I was getting gas blowback in my face from the stock charging handle.

Those features equal higher prices... higher prices for features that not everyone wants.
 
Bingo! Thank you.
Keep price down and add what you prefer later. We all don't like the same accessories.

Which is why I am a huge advocate for building your own rifle or buying a complete OEM style rifle and adding the stock and hand guards of your choice. That way you are moot paying for parts that you don't use.
 
half the fun is applying our own personal "Gucci" to our guns.....
Prolly they should offer the rifles with NO furniture at all!! Then we won't all have a box of old pistol grips, stocks and hand guards!! ;)

Some manufacturers do offer rifles like that, or at least they did last time I checked.
