Unfortunately I have had nothing but problems with this rifle since the date of purchase. I recently purchased a vortek tuner kit for it and the installation itself was straight forward, but the spring compressor I built was crap, and the end result was my safety spring got mangled. I have managed to bend it into a position where it is out of the way and works out of the housing, but the rifle does not come down all the way and successfully charges the spring. Any ideas what could be happening?
