*COMPATIBILITY: There may be a fit issue with some older SMG45 models. A few stocks have been returned unable to fully seat into the customer's receiver. When returned, these stocks all fit Haga Defense's SMG45 just fine. I am looking into this issue. If your SMG45 came with the factory "Pistol End Plate w/ QD Socket" installed then the Haga Defense MBT stock should fit fine. Beyond that I am unsure at this time. Sorry for any inconvenience. 

UPDATE: If you are having fit issues, the rear takedown lug may be to blame. This is the part on the receiver that the rear takedown pin passes through. Loosening the 4 torx head screws that secure it may allow the part to move enough to correct the issue. Once proper fit is achieved retighten the 4 torx head screws. 

WARNING: When the stock is locked in the folded position, lift the stock upward on the hinge to unlock it before unfolding. Failure to do so can result in damage to the hinge. Haga Defense will not accept returns due to damaged hinges. 

Stock: Made in Switzerland
Adapter: Made in the USA
