I would like to install a carrying handle on my mp15-22. How do I decide which one to buy? What do each of you use? Do you have one brand that you prefer over another?
If it is possible, remove the carry handle from the packaging and check for slop (movement) in the sight. My first carry handle had a very loose rear sight, so I replaced it, and my new one is nice and firm. If you will be purchasing mail order, then avoid the cheap ones. My first one was a UTG I purchased at a local gun show (I was a newbie then and didn't check for slop). It worked fine, and would group 2-1/2" at 50 yards (with my bad eyes), but I just didn't like the slop in the rear sight. The new one (shown below) groups 2" at 50 yards. I only use the small aperture. The large one shows the front sight as just a blur, for me.
