jasmi's Review of JMac Customs 1913 Adapter for MP5K and Clones

Would not fit a genuine, euro-imported H&K SP5K.

Adapters from B&T and CNC Warrior line up just fine, but the holes on this adapter were completely misaligned (literally half a pin-width off).

Contacted JMac and they said some fitment is required, i.e. break out a drill.

Requested a return as the part was clearly defective given the product description.

They refused the full refund and attempted to enforced the 20% restocking fee. But I disputed the charge and won.

(Stay away from this company or at least buy through a reseller like Optics Planet to avoid the inevitable restocking fee.)

FYI, they don't even list this part on their site anymore. It's that bad.
