U-Shape Dual Aluminum Alloy Bracket Mount for M40/M16 (30MM-Caliber)

Pros: This is really good and very useful mount. You can use it in a different ways, so it is going to be your universal accessory for large variety of needs. Holds fine on a rail and hold which ever you like pretty tight. It is well build and looks and feels solid.

Cons: Did not found any con on this peace of metal. It works and holds tight.

Other: Fine made mount. It's cheap and durable. If you can wait for delivery then buy it. Such mount will cost much more in your gun shop.

Pros: I bought one of these mounts for a Ruger 10/22 build that will be used by a local pest control officer to eliminate problem animals in an urban setting. Having owned MANY scopes and various mounts over the years, I have to say that this is most likely the most solid I've ever used. Here are the highlights: - The lock knobs are large enough to snug up with with bare hands. Additionally, each one has a hole drilled in the side that you accept the hex wrench that you use to tighten the ring cap screws. This gives you a handle of sorts to finish tightening up the knobs. - The mount itself is made of a single piece of aluminum and is VERY solid. - Each ring cap has 3 lockdown screws on each side, allowing for an extremely solid grip without requiring excessive pressure that could damage your scope tube. - The short pieces of rail on each ring allow you to mount additional accessories such as tac lights, lasers, IR illuminators, etc... However, they are fairly short (only about 1" long) so they may not work for larger accessories. - The base of the mount has a hole that runs through the middle lengthwise. This is to retain the use of your iron sights, and to (slightly) reduce the weight of the mount. I don't have iron sights on my rifle, so I can't comment on how useful this feature is. I do know that with my scope (50mm objective) the sight hole is blocked by the scope bell.

Cons: - A little pricey, but worth it. - Holes in locking knobs were not cleanly finished, (cosmetic issue only). - Mount is fairly heavy (not really a con, just be aware) - Picatinny rails on rings of questionable utility.

Other: All in all, this mount is an excellent product. If you need to know that your scope will not move, buy this.

Pros: Holds Very tight. 6 bolt per ring for a very solid hold on your scope. attaches to your picatinny rail VIA 3 bolts and cross pins and a solid 1 piece metal bracket. Slightly Cantilever.

Cons: Heavy pig. useless rails all over the place. Pricey.

Other: Great Heavy duty mount, expensive and a tad too much extra crap on it, I'm sure Chris Costa would endorse this.
