Out of all of the AR upgrades out there, one of the must haves for me is an upgraded rail/handguard. Pretty sure most AR owners feel the same. A few years ago Fortis Manufacturing introduced their new SWITCH rail which features a Quick Detach system that lets you install/remove the rail quickly for maintenance, adjusting a gas block or multiple rail configurations, etc. The Fortis Mfg SWITCH rail only comes with the KeyMod mounting system at 3, 6 and 9 o’clock spots. With Magpul promoting and supporting M-LOK it was only a matter of time before the new M-LOK SWITCH rail would be produced.
Fortis Mfg has partnered up with Rainier Arms to offer the Rainier Arms exclusive M-LOK SWITCH 5.56 rail. The M-LOK SWITCH is now available in 9 1/4″, 12″, 13″ and 15.5″ lengths, all with the Rainier Arms logo on them. While M-LOK and KeyMod seem to have about the same support from accessory manufacturers, many users prefer the clean look of the M-LOK system. If you’re on the M-LOK train, you might want to check out this awesome new Rainier Arms M-LOK SWITCH 5.56 rail.
This version of the quick detach rail system SWITCH is a Rainier Arms exclusive.
The SWITCH is an extremely lightweight, yet robust free float rail system designed for the 5.56MM platform. When designing the SWITCH, we wanted a handguard that was easy to install, but also be able to quickly change rails for a variety of mission or competition specific setups. The rail features a brand new patent pending locking mechanism that allows tool-less removal of the rail.
The rail features M-LOK slots, QD attachments point as well as a full picatinny rail on top.
The rail design not only looks great, but is very functional in your hand. The piece adds minimal weight to the rifle and you won’t be disappointed!
