5" Heightened Aluminum Alloy Scope Mount Base for M4A1 - Black (144mm)

Pros: -Build is great -Lets you make your weaver rail higher so you can use a scope and look with paintball mask -Clean no words on it -Fits great

Cons: -Its a little loose on the front weaver rail for the RIS grip. -Other then that nothing really bad about it its more for the scope weaver rail on the body not on the front weaver rails.

Other: If you have to wear a paintball mask and you cant look in to your scope you will need to buy this bad boy. Buy 2 of it and stack it on each other but if you got a good scope then only 1 is really needed.

Pros: this is nice and simple to fit and with most sporting guns that have open sight, the see through option is useful encase you knock the scope or the target is very close. Will take any size scope especially those with a large objective lens.

Cons: none really, although the nuts dont need to be as large as they are once this is permanently fitted.

Other: great value for money and probably worth getting more than one.

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 and hold which ever you like pretty tight. It is well build and looks and feels solid. Not sure about previous reviews, probably the quality was improved since those time, mine is just excellent.

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: - It's flat black - thumb screws are really nice - fits onto my GOG G1 paintball marker - It's pretty tall (i thought i needed 2 and ordered 2 but i'll save the other for back up)

Cons: - Heavy - scratches easily - thumb screws rusting a little

Other: My 45x1 red dot scope mounts on it fine and it mounts on my paintball marker fine.

Pros: This sight riser is made of high quality metal, has a durable coat of black paint and is easily mountable to any picatinny rail. Mounting is very secure, no wiggle at all. This exceeded my expectations for the price. I also like how it has been hollowed out in the center and you can still use iron sights if you need to.

Cons: Nothing I can think of.

Other: Sweet deal for the price, I would recommend more for an airsoft gun that doesnt have a hopper, and I suppose if I owned one it would work well on a real gun too.

Pros: It's sturdy, easy to attach and remove quickly. The thumb screws are nice and strong. The painted finish is a nice flat black. I saw no flaws or rough spots. Provides a nice height increase above the top of your gun.

Cons: None - it is just right.

Other: Works great, looks and feels professional, price is competitive and can be used to attach all kinds of standard picatinny rail-mount devices like scopes, sights, etc.
