Midwest Industries AK Picatinny Adapter Features The Midwest Industries AK Picatinny Adapter replaces the AK s factory trunnion with a Milspec 1913 rail giving the rifle a standardized Picatinny interface for mounting fixed or side folding stocks. Steel tension blocks inside the adapter keep the fit snug against the receiver preventing the wobble that can develop with lower quality stock adapters. The body is machined from 6061 hardcoat anodized aluminum a finish chosen for its resistance to wear and corrosion under hard use. It is built specifically for AKM pattern rifles with a 32mm internal receiver width and it does not work with Yugo pattern rifles or guns using 4.5mm or 5.5mm pins. Installing the adapter is a straightforward job that Midwest Industries estimates at 15 minutes or less with the right tools though the user must cut off the stock tang first and some additional gunsmithing may still be needed depending on the specific rifle. Once fitted the adapter opens the door to the wide world of 1913 style stocks letting an AK owner switch to a fixed or side folding stock of their choosing. Midwest Industries builds the adapter entirely in the USA and backs it with their lifetime warranty. The Midwest Industries AK Picatinny Adapter is for sale at GrabAGun for AK-47 and AKM owners looking to modernize their stock options with a standardized rail interface.
