Magpul M-LOK Polymer Picatinny Accessory Rail

Great product

Solid product

Quality product

I purchased a Kel-Tec CP33 pistol, which utilizes an M-LOC dust cover for the accessory mount. Considering the lightweight nature of the pistol, I went with the polymer picatinny rail rather than an aluminum one- plus, the glass-filled polymer is more easily modified (and let's face it-I'm just mounting a lightweight light, not a heavy bipod). Magpul makes a shorter version (3-slot, I believe), which should fit the dust cover exactly without modification. But since I already had an Olight (this version does NOT have the adjustable mount), I knew that I'd need the next longer Magpul M-LOC mount. Only problem is, it doesn't really fit this pistol's slots (and I anticipated this). Thus comes the modifications. If you're in a similar boat, you'll need to carefully trim away the extended boss under one end of the mount where the supplied screw/nut goes. Take a 3/8" Forstner bit and carefully create a new recess in the center of the mount (see pic). Then drill the dead center of the recess to accommodate the machine screw's shank (I don't remember which size I used, sorry). A drill press really comes in handy with both of these operations. With a Dremel, I then created a small clearance recess on the one end of the mount to clear one of the dust cover's small machine screws. The Magpul's supplied machine screws and nuts then fit perfectly in the mount and onto the dust cover. Reinstalled the assembly onto the pistol, attached the light, and, VIOLA- everything is exactly as it should be. A solid mount, and the light is situated where it should be for my hand. Of course, I probably could have just ordered the 3-slot mount and the adjustable Olight, but I already had this light. The modifications really didn't take long at all (it took longer to write this!), and for me, what little work was required was well worth it. It would have been great if Magpul had made this mount already with the middle screw location molded in (are ya listening, Magpul?), but in lieu of this, I made it work, and I love it!

Good product but the screws were a tad too long to install it on my KelTec S2K gen 3. Others have written the same observation but, unlike my usual practice, I didn't read the reviews before my purchase. I had to file them down...and that took longer than installing it. But it's all good and secure now.

Great product.

Just perfect for IR torch mount on my Bergara MGLite backcountry hunting rifle. Lightweight and sturdy

Unless I'm mounting a laser I almost always use polymer rails. The Aluminum rails I save for applications that absolutely demand superior hold and rigidity, mounting and precisely calibrating a laser is one such instance.But For the most part a polymer rail section is the superior choice in terms of both cost and functionality. The majority of accessories; such as Lights, Bipods, and Fore Grips, have no need for a precision mount. The polymer rail are also more forgiving of abuse, which most frequently comes from being smashed against something or having the retaining nuts/rail accessories over tightened. A polymer rail can deformed a fair amount and still be plenty functional. Additionally the precise application of a sharp knife can even return a previously unusable rail to a serviceable state in a relatively short period of time. Try doing that with an aluminum rail.My last reason for preferring polymer over aluminum has to do with protecting the free floating barrel shroud on many AR-15s. When stressed or torqued a polymer rail will give a bit due to being more ductile than aluminum, this means less force is transferred to the free floating barrel shroud if one of the rail accessories gets bashed or torqued somehow. This in turn means that your barrel shroud is much less likely to be damaged by a blow that is, at least in part, absorbed by a polymer rail.And it just so happens that Magpul makes some of the best you can ask to buy.
