Adding a Picatinny rail onto a rifle\u2019s handguard or fore-end adds extra weight, and some shooters complain about the extra bulk and \u201ccheese grate\u201d feeling it has on the hand. And although both the <\/span><a href=\"https:\/\/www.targetbarn.com\/broad-side\/picatinny-rails-vs-weaver-rails\/\"><span style=\"font-weight: 400;\">Picatinny and Weaver rail systems<\/span><\/a><span style=\"font-weight: 400;\"> work great for mounting scopes, their shortcomings in accessory attachments left a lane open for improvement. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These shortfalls brought the next generation of accessory mounting: KeyMod and M-LOK. The KeyMod and M-LOK are based on a slot system rather than the rail system of the Picatinny and Weaver mounts. This means a smoother surface and more mounting options. Both gained popularity since their introduction to the market in the 2010\u2019s &#8212; but which system is better?

They released the KeyMod system to the public in 2012 in hopes of standardizing universal attachment systems. It is an open-source design, meaning the design can be used freely by any company to make rails or accessories. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Instead of having a hand guard with a picatinny rail attached, the KeyMod was designed so that accessories could be mounted directly onto the rail. This also allows for picatinny rails to be mounted onto the handguard wherever needed.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><b>How to Mount KeyMod Accessories<\/b><\/h3>\n<p><img decoding=\"async\" class=\"alignnone wp-image-706 size-full\" title=\"Mounting KeyMod\" src=\"https:\/\/www.targetbarn.com\/broad-side\/media\/BSS-TB-Rails-Vid-1.gif\" alt=\"showing how to mount a keymod accessory\" width=\"800\" height=\"450\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The KeyMod is a <\/span><b>mod<\/b><span style=\"font-weight: 400;\">ular system with the mounting slots having a <\/span><b>key<\/b><span style=\"font-weight: 400;\">-hole profile.

Just like the KeyMod, the M-LOK allows for direct accessory attachment. Magpul sought a design that worked better with non-metal mount surfaces. The polymer accessories Magpul offered didn&#8217;t work well with the KeyMod\u2019s conical nut. So, they created the M-LOK system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Unlike the KeyMod, the M-LOK is not open-sourced, but rather free licensed. This means that manufacturers can only make <a href=\"https:\/\/www.stngrusa.com\/m-lok-handguard\/\">M-LOK handguards<\/a> and other products using the M-LOK standard after acquiring a license from Magpul.<\/span><\/p>\n<h3><b>How to Mount M-LOK Accessories<\/b><\/h3>\n<p><img decoding=\"async\" class=\"alignnone wp-image-707 size-full\" title=\"Mounting MLOK accessory\" src=\"https:\/\/www.targetbarn.com\/broad-side\/media\/BSS-TB-Rails-Vid-2.gif\" alt=\"showing how to mount an mlok accessory\" width=\"800\" height=\"450\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The M-LOK is similar to the KeyMod system in that both involve locking a nut into a slot on the rail.

The most significant variation was in the Repeatability test. M-LOK came out on top with the least amount of MOA shift when removing, then reattaching, an accessory rail with a laser sight. They found that in a drop test, M-LOK accessories remained attached 100% of the time, while KeyMod accessories rem<\/span><span style=\"font-weight: 400;\">ained attached only 33% of the time. From this testing, the M-LOK was selected for use on the Suppressed Upper Receiver Group and Advanced Sniper Rifle programs.<\/span><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-688 size-full\" title=\"MLOK handguard\" src=\"https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589.jpg\" alt=\"mlok handguard accessory rail\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589.jpg 1024w, https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589-300x200.jpg 300w, https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589-768x512.jpg 768w, https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589-200x133.jpg 200w, https:\/\/www.targetbarn.com\/broad-side\/media\/BSS5589-750x500.jpg 750w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">While this testing did not fare so well for KeyMod, that does not necessarily mean that it isn\u2019t a feasible option for applications outside of military use.
