Great sights for the not rich

by Mike, from United States, TX Written on August 7, 2014
These are very nice for the money and work great. Nice tight fit and solid feel. They open with a very good snap. I bought front and rear; they make a nice sight picture. Co-witness with my Lucid HD7 just fine but I keep them folded down out of the way....

Quality Sight-Economic Price

by hondaracer173, from United States, NC Written on July 31, 2014
Great sight, especially for the money. Tight fit on picatinny rail, sight in was a breeze, love the push-button flip up activation. I used these sights for transition sights on a 45 degree angle mount, I can be looking down the sight of my red dot and flip these sights up without moving my head or changing how I'm holding my AR just by pushing the button. Will buy again for another AR build....
Pros:
  • GREAT PRICE
  • great quality
Cons:
  • None

Perfect for back-up sights

by Legacy Reviewer, Verified Owner from United States, TX Written on March 28, 2014
These sights can be used as backups or primary without optics if necessary. The rear sight doesn't usually get much abuse. They're not indistructable, but for most uses it outperforms.
Pros: compact size, durable, holds zero well...

Gets the Job Done

by Legacy Reviewer, Verified Owner from United States, CA Written on January 5, 2014
Some People will say this product is inferior because it is not metal but if you have another reliable primary optic then you would almost never use this back up sight anyway and I would much rather have this back up sight than no sight. Also I feel that there are enough polymer products out there that have shown that polymer is a durable material. These are my personal opinions
Pros: Inexpensive but not cheap...

Magpul MBUS Rear Flip Sight, Gen 2, Black MPIMAG248BLK

by Legacy Reviewer, Verified Owner from United States, TX Written on May 19, 2013
This item is the rear sight of a second pair of like Magpul front & rear flip up sights, all installed on our AR15s & used as backup sights. Although it's inexpensive & constructed of plastic, it is rugged, compact, light in weight, and made in the U.S.A. Mounting it to the 1913 Picatinny rail is simple and I've found it to stay put; haven't found it to loose due to vibration.
Pros: Compact, light weight, secure in either folded or flipped up position
Cons: Tabs used to flip up spring-loaded sight are small & a challenge to use if wearing gloves. ...
