Brownells 75th Anniversary - A Shooting Heritage

Precision Stamped Steel Ready To Bend & Build

Yugo M92 Underfolder – Stamped specifically for use with the Yugoslavian Zastava M92 and M70 variants (7.62x 39) with underfolder stocks. Requires flat-sided front trunnion; do not use the bulged RPK-style trunnion. Finish work requires a 4mm chucking reamer to open up the trunnion holes.

Precision-cut, ready-to-bend steel flats save time and frustration when building a custom AK. No more trying to salvage a beat-up receiver from a “donor” gun. These flats are stamped from the correct 1mm thick sheet steel, with top rails pre-bent, stepped, and trimmed on CNC equipment. Hammer and trigger holes are slightly undersized, ready for precise final reaming after bending; use 7mm and 5mm chucking reamers. All flats come with lower bolt guide rails that include magazine stabilizers on both rails and the hammer spacing bump that centers the hammer in the correct position. Rails require drilling for center support holes after spot welding. Refer to the listing below and choose the correct flat for your project.
