ACR Handguard - M17


This is a modular handguard to give your M17 some modern assault rifle style, inspired by the popular Adaptive Combat Rifle (ACR). 5 rows of MLOK* slots allow for plenty of accessory options. The faux gas key is also removable with a single bolt to facilitate the use the of shorter barrels and an integrated suppressor configuration.

Color Option 1 is the handguard body

Color Option 2 is the "gas key"

* MLOK is Magpul's open source version of KeyMod. Keymod accessories will NOT work with MLOK. It is also a "Your Mileage May Very" feature, which may require some tinkering to fit some accessories. In my experience, some MLOK stuff has fit right out of the bag, while other accessories needed to be tweaked, such as longer bolts or removing the thread lock that Magpul puts on their bolts.

Take care when using 3D printed MLOK or KeyMod rail slots. Printed items can not be torqued to spec or tightened without risking some cracking. Snug items on, and avoid dropping your marker or breaking your fall with it. For a more robust part that you expect to add a lot of accessories to, ask for "Quad Rail" instead :)
