These are blemished products and color may vary between components. Product images may not fully represent what you will receive. They are guaranteed to function correctly.

The Geissele Automatics Border Patrol Center Tab MK20 Assembled AR-15 Upper Receiver gives builders a mil-spec upper and 9.6" free-float handguard mated as one precision-fit assembly. Built for 10.5-inch and shorter SBR or pistol builds, this kit delivers full-length Picatinny and M-LOK coverage without any handguard-to-receiver play.

Features:

• 7075-T6 aluminum Center Tab upper receiver
• 9.6" MK20 free-float M-LOK handguard
• Full-length M1913 Picatinny top rail
• M-LOK slots on all four quadrants
• M4 feedramps, dust cover, and forward assist included
• .250 mil-spec takedown holes
• Cosmetic blem, color may vary between components

The Center Tab handguard locks into a matching recess machined into the upper receiver, keeping the two components rigidly aligned with no rotation under hard use. Both the upper and the 9.6" MK20 handguard are precision machined from 7075-T6 aluminum at the Geissele facility to mil-spec tolerances, with M4 feedramps, milled T-marks, a dust cover, and forward assist included, finished in Type III hardcoat anodize.

This kit is designed for 10.5-inch and shorter SBR or pistol builds and is compatible with standard mil-spec bolt carrier groups and .250 takedown pin lower receivers. Barrel, BCG, charging handle, and muzzle device are not included, and because this is a blemished unit, some color shade variance between components should be expected; function is unaffected.

Geissele Automatics designs and manufactures precision AR-15 components for both military procurement and the civilian market, with decades of fielded use behind the Border Patrol product line.
