Question: is it a good scope for a rock river AR10?
Document: Very nice scope, optics are nice and clear, all adjustments work perfectly. Comes with very nice mounts, and an extra battery. Zeroed in very easily and held zero after several hundred rounds on a rock river ar-15. No complaints and seems to be great value for the money.
Since the scope is only 10.3 inchs long it looks great sitting there where as a full size scope would not. I mounted it in a 100mm block type set of 30 mm rings an its rock solid.
After completing an AR10 build, I wanted a scope to get started with, but this is an excellent scope for the money, and definitely worth the expense. The only problem (not the scope), was I had to buy an 1/2&#34; extension to get the scope up higher with the bolt.
It has features that can be found only on much more expensive optics. I have 4 of these very UTG's on rifles ranging from my Colt M4 in 5.56, my ArmaLite AR10 in 7.62 X51 (.308 WIN), one on my Remington 700 tactical in 7.62 X51, and also, one on my Pre-'64 Win Mod 70 in .338 Win Mag. All were properly mounted with great care and have given me accurate and dependable service.
this scope works great, just what i needed to help me get my shots on target. easy to mount and dial in, which is good for me!! !
this is really a nice scope . It has lots of nice features. is really made of good products.would buy more.
This scope is awesome for the money. Have one on a ar15 and it looks and works very good. clear optics good view.
Quality is not there. Scope looks good, that's about it. Mounted squarely on my rifle, looked through the sight and the crosshairs were rotated clockwise!
Nice scope. Fits great on my AR. Multi. Color is very neat for out doors. Good price. Easy to use.
Im very happy with this scope, Just as good as any hi price scope. Hope you don't go up on price, you will sell a lot of this babys.
Answer: yes
