So my surefire can just got approved and I am wondering if any of you guys have had any trouble carrying your rifles in the GSII with the can attached and with the barrel in the bottom of the pack. Rifle is a GAP with nightforce glass so its a little on the heavy side and I am wondering if this could adversely affect the mounting system and/or my zero if the rifle is packed with all the weight resting on the can. My guess would be no, but would love to hear if anyone running a similar system has had any issues with this.
