This went on for four or five years or so while the rolling mills got their acts together, at which time they reverted back to sheet metal receivers. The stop-gap measure decided upon was to switch production to receivers machined out of solid forgings of ordnance steel, which the steel mills COULD make.

Consequently a lot of receivers were rejected outright or, in use, exhibited issues of flexing and/or rivet and pin holes would become elongated, resulting in premature scrapping of the rifles. Although the limited production prototypes and trials rifles were fine, when volume production started they unfortunately discovered that Russian steel-making and rolling mills were not up to snuff regarding raw materials in the quantity required. Mine, for instance, mounts a Russian ribbed top cover which fits perfectly - just because I prefer the look of the ribbed top cover.Ĭonsider that the pedigree of the MAK90 goes like this: When Russia first put the 'Type 1' AK in production, the receivers were made of stamped and folded sheet metal 1mm thick. Don't know about folders, unless you find one specifically made for a MAK90.īut magazines, web gear, and other common AK parts, and even scope-mounting rails work fine on the MAK90. Imported buttstocks can likewise be made to fit, but U.S. Likewise the fore end may need the tab that fits beneath the trunion filed down a little to fit. Not a real problem, as you can just remove the top hand guard from the gas cylinder and swap it on to the hand guard of your choice.

Later European AKs use a non-vented gas cylinder that require vent holes in the gas block. Note that ALL MAK90s use the early style gas cylinder with the vent holes on the side. In my (limited) experience, most European wooden furniture will either fit, or can easily be modified (sanding or filing) to fit.
