Thread: Jw15 modifications

Had a bit more of a play with these, it would be interesting to know how many of these have to be reworked at the factory to be functional. The two I have start with 92 and 93 so presumably that is the manufacture year. The older one which I have had from new works fine, the newer one doesn't (kind of). Measuring them and comparing components the sear is located almost 2mm further forward on the newer gun. This means that the safety is almost unusable and there is no half cock position on the bolt, if the trigger is pulled with the bolt in the half cock position it will close and release the firing pin (it may or may not fire though). The bolts and receivers are remarkably similar though. Interestingly the length of pull on the newer stock is 10mm longer.

Onto the modifications, put a bit of shape in the trigger, doesnt look like a piece of keysteel anymore, and a trigger guard, base metal and extended the magazine release.
