Has anyone had quality control issues with their fx impact m4. I bought this less than a month ago and I noticed the grip was moving. I took it off and the hole was boogered and the bolt that was holding it was to short. I put another grip and it tightened up no problem. Then I bought a new saber tactical bag rider and took the side plates off and noticed the holes weren't drilled center. Contacted Utah airguns and wouldn't warranty the parts. This is a shame to spend over $2k and won't stand behind their 3 year warranty when this is clearly manufacturer defects.
