I recently purchased a new to me Arsenal SLR-107. I am having the hardest time getting it zeroed, even with with optics. It is obvious something is bent or canted but I am not sure if it is something that I can fix or if it is even fixable.
Pretty much when I am shooting it is constantly just going left. With Iron sights the front sight post is maxed out to the left and I am still shooting 2-3 inches left at about 10 yards and at 25 yards it is about 10-11 inches to the left. The same is said for optics. I have tried it with two different optics, an ACOG and a PA Prism 1x. The acog on the mount it was on was maxed out in windage and it was still shooting 3 inches left at 25 yards. With the PA Prism I was able to get it zeroed windage at 10 yards but at 25 yards it shot 9 inches left. (This is when I came to the conclusion something was definitely wrong)
The groupings are tight but all to the left. From what I am able to google fu obviously the front sight appears to be canted maybe or even the barrel/trunnion may have been put at an angle. (Speculative) Is there a way to confirm the issue or possibly fix this or am I stuck with a gun that shoots constantly left? All help is appreciated. Or if there is someone I could show the gun to, or send off to see about helping get this issue resolved? Thank you all in advance.
