Precision Stamped Steel Ready To Bend & Build

AK-74 Bulgarian Sidefolder – Made specifically for the Bulgarian side folding stocks. Use with the most common variant kits. 1⁄8" alignment pin holes are pre-drilled.

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.
