Magpul CTR Stock

Magpul CTR Stock

The collapsable stock is a defining feature of the iconic AR-15. The original design was simple: 6 positions achieved with a latch, lots of loose wobble and very little comfort to the shooter. Since the commercial availability of M-4 type rifles to civilians, the market for improved stock design exploded. There are many different manufacturers of collapsible stocks with different aesthetics, but few companies have gained the recognition and customer loyalty of Magpul Industries.
Magpul's original collapsible stock that was very popular was the MOE (Magpul Original Equipment) Many rifle manufacturers were producing rifles from the factory equipped with the MOE stock and other furniture in the MOE line. While the MOE stock was a great design, sleek and easy to install yourself, it began to fall out of favor as new common features were becoming a standard on riflestocks. That, and more discerning users could notice a small amount of play/wobble between the MOE stock and the receiver extension tube.

Magpul CTR Stock

Enter the Magpul CTR (Compact/Type Restricted). An evolution of the MOE stock, the CTR brings two new features to the table. The first is a friction lock that is designed to take up some of that wobble and play of its predecessor. Performance of the friction lock may vary depending on the buffer tube's dimensions, tolerances, etc. On my milspec extension tube, the CTR when locked is very nearly rock solid with no discernible play, while the MOE on the same tube has a small amount of rattle to it.

The second additional feature Magpul added to the CTR is an ambidextrous quick-detach sling swivel port. Whereas the MOE only has slots for slings to be run through the rear or forward facing base of the stock, the ability to utilized QD swivels on the CTR greatly adds to the end user's options customization. Many rifles have QD attachment points on handguards or receiver extension endplates, and having the ability to alter the sling's attachment points at the push of a button is a great addendum to the flexibility of the platform.

The Magpul CTR stock and MOE stock share the same side mounting slots for mounting cheek risers to the stock. I have a LaRue Tactical RISR on my CTR, as it better aligns my dominant eye with an optic that is mounted on a taller base/rings. Unlike other cheek risers that are incompatible with AR15s due to interference with the charging handle when the stock is fully collapsed, the RISR has a reciprocating cheek piece that rides back with the charging handle when the LOP is set in the shorter positions. This of course isn't an issue with other rifle platforms that can make use of the Magpul CTR, like side charging rifles, modified AK-47/74's, or even chassis made for bolt action rifles.

Magpul CTR Stock

For a modern, adaptable carbine/rifle that needs a collapsable stock for transport, storage, smaller framed shooters or shouldering whilst wearing body armor, a collapsable stock like the CTR is exactly whats needed. The addition of the friction lock and the QD port make it an excellent evolution of the MOE, and a widely used stock overall. If you are going to pick one up for yourself, just be sure you know whether your extension (buffer) tube is milspec or commercial. I consider the walk from the parking lot back to the store to exchange for the right stock to be a "walk of shame" for our hobby, especially if you've done it more than once like I have!

Smith and Wesson M&P 15 MOE Midlength Review

m&P By Bradley Johnson

The black rifle. Most non-shooters recoil at the sight, or very mention of it. In fact, reading reviews of local shooting ranges has lead me to believe that many people think they are out right illegal. Of course (and fortunately for me) that is not the case.

I was born and raised in California. This puts me at a disadvantage among the shooting community. However, I was determined to throw my hat into the ring.

If black rifles are illegal, then someone forgot to tell RifleGear; my local shop; they carry everything the modern sportsman could want. I entered with the intent to purchase an entry level rifle. I've shot in the past, but this would be my first "black rifle". Apparently, I was not alone in my endeavor, because the line was literally out the door!

After handling several rifles (Spikes, Daniel Defense, etc), I left with an M&P 15 MOE Midlength... well, if only it were that easy. 10 days later...

After a strip down, inspection, and cleaning I was sure that my day at the range would be a good one. My first impression of the rifle was sheer elation! It was accurate straight out of the box, and it felt great in my hands. Everything functioned perfectly, and the Magpul add-ons were light, and handled well (surprise, surprise). I thought it was odd that the magazine was a 30/10 (30 round mag modified to only accept 10 rounds), instead of a 10 round mag, but I guess Smith & Wesson leaves the "California Compliant" part up to the dealer. The "Art of the Carbine" DVDs included with the rifle were really informative. Not only do they cover tactics, but also breakdown, cleaning, malfunctions, etc.

My wife felt the same way, and since I'm not much to look at, I've included a video of her firing it at the range.

Claim to Fame: Reliability. I've put one thousand rounds through this rifle without a single hiccup. Smith & Wesson definitely delivered a product worthy of their legacy. The MOE furniture only adds to the overall experience.

Target Market: This is a solid rifle. Magpul is a leader in firearms accessories, and for good reason. Everything about this rifle feels right!

FNBs (Features & Benefits of this product):

  • Magpul!
  • Magpul adjustable stock, pistol grip, hand guard, folding m-bus backup sight, and vertical grip. The magwell is also flared for easy insertion of mags, and the Magpul logo is stamped on the lower receiver.
  • M4 A2 front post sight
  • "The Art of the Carbine" DVD set. The DVDs cover tactics/range practice routines, cleaning, breakdown, malfunctions, etc. In other words, everything that the Smith & Wesson manual fails to mention.

What other aesthetic options or finishes are available?: The Smith and Wesson M&P 15 MOE Midlength is available in black and flat dark earth.

What others are saying?: “Testing of the M&P-15 MOE Mid began with rapid-fire drills using a randomly loaded assortment of .223 Rem. ammunition—ranging from lightweight, varmint-type offerings to those appropriate for high-power competition at Camp Perry—and not once did the rifle experience a malfunction. Although this illustrated the rifle’s ability to digest a wide range of ammunition types, it doesn’t reveal its accuracy potential. As such, we mounted a Nikon 3-12x40 mm M-223 riflescope in the company’s two-piece P-series rings, then shot five consecutive, five-shot groups at 100 yards with three ammunition types. The rifle clearly preferred PMC’s Precision 75-grain BTHP load, averaging 1.43 inches for 25 shots, and the single best group measuring slightly more than an inch. More economical loads produced respectable groups, too.

With the M&P-15 MOE Mid, S&W offers shooters an AR that, right out of the box, is well-suited to handling a range of tasks, from protection and competition to hunting. As such, it would make an excellent choice for those desiring an AR-style rifle, be it their first or simply an upgrade.” - American Rifleman
