Can anyone ID this, and, most importantly, tell me where I can find the missing parts, the barrel mount/locking plate and screws/bolts to secure it. I received it with some assorted upper parts, and it appears to be prefect, albeit incomplete, for a project. It has some "idiot marks" on the bottom, but at least it's not a DL number scratched on the side. ![]() Thanks. Attached File Attached File Attached File Attached File |
Yes, I have Autohumorosis.

I'd contact PWS...they still use the same rail with MLOK (PickLoc) on their current rifles and sell it separately as an upgrade to the older PickMod rail, so they should have the hardware available. https://primaryweapons.com/mk1-mod-2-m-piclok-replacement-rail-111/ Attached File |

That rail is made by Primary Weapons Systems (PWS). Specifically, it is a proprietary replacement handguard for their MK111 series long-stroke piston upper receivers. Based on the machining of the accessory slots, this appears to be one of their older KeyMod configurations (or an early hybrid variation) rather than their current generation M-LOK or PicLok handguards. Keep in mind that because PWS uses a proprietary long-stroke gas piston system, these handguards feature specific internal dimensions and top-rail cutouts to clear their gas adjustment blocks, meaning they won't fit a standard direct-impingement (DI) AR-15 upper.
