Question: will this fit a ruger sr22 with a 3.5" barrel? The rail on there is pretty short so wondering if the mount on this is short enough to fit! Thanks!
Document: I put this on my Core 15 5.56 M4 rifle and it has been a nice, low profile laser. I was a bit sketchy about it holding a zero but it does so just fine. When I first unboxed it, the first thing I noticed was that the mounting screws do not lock the laser into a picatiny rail slot. However, the duel mounting screws hold it on their plenty tight and I soon realized that it would not be an issue.
Perfect for my crossbow underbarrel rail. Incredibly easy to sight in. It comes with allen keys for mounting and adjusting.
Bought sight for practicing aim and sight line up with gun barrel at range, that way I could make adjustment to my shooting form. Because of this, I attempted to align the sight properly using hex key, tightened too far and the screw went into housing and became stuck, no way to fix issue. I'll just chalk it up to improper use. Update, seller sent me a replacement and instructions for proper alignment procedure.
I added this to my Mossberg 715t .22 rifle and it works great. It has 2 allen-wrench positioning screws (plus the tools) to zero the laser up-down or left-right. It fits the picatinny rail nicely and is secure after a full day at the range. I highly recommend this product. Oh&#8230; its nice that it came with an extra set of batteries too!
You can not go wrong with this laser. Its well worth its price. I have it on a 715T Mossberg and love it.
Working fine for the price will buy another one for other pistol.
