They've been on the market for a while, nice features sets at veryreasonable MSRP's, but not so easy to find informative reviews of their reliability and accuracy.

What are their drawback and strengths?

Example:





Rifle-length gas system
15" aluminum S&W® M-LOK® forend
B5 Systems SOPMOD stock
PWS 556 muzzle brake
Williams Gun Sight Company Folding Sights
B5 Systems P-Grip 23 pistol grip
Ambidextrous Radian Raptor-LT™ charging handle
Flat-faced trigger
Target crowned, threaded barrel
2" M-LOK® rail section included
Chromed firing pin
Forward assist
Dust cover
Forged, integral trigger guard
Armornite® finish on barrel (internal and external)

The reason is likely that it's just another AR15 in a vast sea of AR15s, all of which have similar features and performance.

So since it doesn't do anything better or worse than any other AR, and doesn't introduce any sort of innovative features, then there's little need to do an entire review just to say "It's the same as any other AR".

The rifle-length gas on a 16" barrel would be a potentially problematic characteristic. It'd be great for a silencer, and likely gets some help from the factory muzzle device, but I have always been under the impression that that's too long of a gas system for that barrel length, when it comes to "duty" reliability requirements.

Keep in mind that the specs posted are apparently for a rifle chambered in 6mm ARC.

While it is generally true that rifle gas is less optimal on a 16" .223/5.56 AR15, optimal gas system length and port size vary depending on gas pressure, and 6mm ARC has higher pressure and a different pressure curve than .223/5.56.

So that generally accepted opinion for .223/5.56 gas length may likely not apply here.

(I don't know enough about 6mm ARC to say for certain.)

I see. I didn't click the link. I assumed the OP was referring to a 5.56mm example.

The 5.56mm version of the same rifle is indeed mid-length. OP may want to edit his post, if he wants feedback on the 5.56 version. That or clarify in his title and OP that he is inquiring about the 6mm version.

Bolt carrier groups make or break an AR-15. I've not shot an M&P 15 enough to really know how they would stand up. Feeding can be a problem with any 6mm ARC, I gather. Troubleshooting magazines and finding some that would work the best, that's something only you can do with with rifle in hand. After speculating on the photo and S&W marketing copy, I dunno. S&W forums do have some posts about problematic BCGs, particularly with the gas block.
