Question: Am I able to still use my field sites with this mount installed?
Document: Nicely machined made in USA. This is made of aluminum and fit my JT Distributing upper perfectly. Easy to install and allows use of stock iron sights. There are cheaper plastic and imported versions of this mount but this was exactly what I wanted and at a fair price.
I bought this for my Colt A2 Sporter. It was a nice, tight fit into the carry handle with no movement whatsoever. The iron sights are still clearly visible through the round viewing port. This version appears to have more aluminum material than most which I would expect will add rigidity. I haven't had a chance to shoot it yet, but my red dot mounted solidly.
I purchased this Leupold mount after not being happy with the Ncstar model I started with. This one locks down tighter than the China made one. Only gave 4 stars because it is kinda short. Good mount
Never loosened or gave me any issues. The one real problem I had (and the reason I'm only giving this 4 stars) is that the iron were not clearly visible. The bolt used to secure the mount seems to obscure the bottom half of the sight picture. If you don't care about the iron sights and just want a quality scope mount, this gets 5 stars.
I had a cheaper mount for my M-4 originally, but it would not stay tight.It eventually loosened and the screw broke. I was about to give up on mountinga scope my M-4 until I found that Leupold had such a mount. It cost about twicewhat I paid for the cheap one, but it was my only option.It was well designed, good materials and tight. I am expecting a lot of servicefrom this mount.
I have to give it a 3 because it did not fit two of my rifles. It would not fit in the longitudinal groove of the carry handle of my 1997 vintage Armalite AR-15 match rifle. It also did not fit in the longitudinal groove of my 2013 vintage DPMS detachable carry handle. Those are sizing issues only. The quality of the mount is very good with nice finish, no burrs and it is solid. It looks very well made and I could find no tool marks.
I bought this to mount a scope on my carry handle receiver. I'd heard bad things about cheapo ones so I went with this leupold mount straight and I'm very pleased. I had a slight fitment issue, the sides of my carry handle seemed to be a bit too small to for this to fit in. I'm not sure this is a problem with the mount so much as it's a problem with my receiver. A bit of elbow grease and a lot of force got it on eventually.
It is as advertised! Was a perfect fit for my AR and the perfect mount for a halo sight! Dead on.
This was just as promised. It fit perfectly and works on an everyday basis. Just what I needed and wanted for my M4
Got what I paid for, and at a good price. Using it for airsoft so don't really have any comments on durability.
