at first sight

functions well, very accurate ,lite weight. a little pricey

great shooter, but very expensive

Just attended a Patrol Rifle School in Oklahoma for 3 days in April. There was a plethora of different makes of M4's, including five M & P's. FOUR of these had issues with failure to feed, extract, etc. Four out of Five failure to function correctly is not good. I borrowed one of these because it was having a "magazine" issue, Took a 30 rd mag that had worked flawlessley (sp?) in my RRA & put it in the M & P. First, it wouldn't lock into place without taking out about three rounds. Then it locked in place, but I had to literally pull back with all my might to get the bolt to the rear to jack a round in the chamber. Then, when I tried to extract it with the T handle, it was again tough to do. One of my fellow officers bought one about three months ago & he also had an issue with it & had to have it shipped back to the factory. These were all brand new rifles. Don't put your life on the line with this one- I believe there's a design flaw of spacing between the magazine & the bottom of the bolt carrier group. I would rate it a ZERO if I could.

I think that this carbine is better then the Colt M4 that i carried in Afghanistan. If only it came with the full auto or three round burst capability

I have owned my 15t for alittle over a year. I initially had failures to feed as well. I checked everything I could think of. For me, it was the ammo. My Smith didn't like the the Hornady 75gr. training ammo. No matter what type of magazine I used with this ammo, it was a no go. The Hornady 62gr and 60gr functioned without a flaw as did various brands of 55gr. The weapon is deadly accurate. After changing ammo, I had no failures to feed. Love the fold down sights. Switching my EOtech 552 for a Trijicon RX30-23. Better sight and slightly less expensive. After breaking in the trigger pull the weapon is very smooth. My dept is going with the 15t for our tactical unit. I have no regrets about buying this weapon.
