I am now the proud owner of a Harrier X in .25 cal @44lbs, Is it possible to put the 10 shot mag on this rifle or does it require any modification to accept the mag or is it just not going to be possible at all? I'm across the pond and fac is not an issue. Also I have a silencer that I use on my MP5 subgun that of course is 9mm, when I remove the screw cap on the factory mod I cannot put ot on all the way as the threading for the silencer I have is 1/2x 28 I think, it does a great job but at this point I can only get the threads on one turn, I want to have some adaptor made so it will screw all the way down as it is a heavy silencer and it really makes for a wonderful muzzzle weight, I have a few pics I will post below.
