Product Description
COMPATIBILITY: Because of recent changes to the PS90 by FN this handguard no longer fits all variants. Newer PS90s are wider at the front of the receiver which prevents the handguard from fitting properly or at all. Currently I have found no way to identify the old (thinner) vs the new (wider) without actually measuring the receiver. The handguard WILL fit older receivers that measure roughly 31mm across the front. The handguard will NOT fit the newer receivers that measure roughly 33mm across the front. The image below shows where to measure. I am currently working on a new Gen 4 handguard that will fit all versions. Keep checking back for updates.
Machined from 6061 aluminum and anodized black (Mil-A-8625 Type III Class 2). The handguard mounts to the PS90 with included hardware and no modifications to the firearm are required. Fits all three versions of the PS90 (standard, tri-rail and the USG).
The handguard has M-LOK® accessory slots on the top, sides and bottom. Rails are NOT included but can be purchased separately from our accessories page.
Now includes QD sling mount on both sides.
Weight without rails: 10.5oz
*Some rails and accessories may require shorter screws when using the side M-LOK® slots because of the close proximity to the barrel beneath them. If the rails are purchased from us the proper screws will be included.
