UPC: 6027C
MFR#: MAG247

•Impact resistant polymer construction provides light weight and resists operational abuse
•Spring-loaded flip up sight easily activated from either side or by pressing the top
•Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
•Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons
•Protective wings shield the spring-locking A2 front sight post
•Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well

• MBUS – Front Gen 2
• Weight, w/ hardware: 1.2 oz.
• Height above rail, stowed: ~0.51 in.
• Length, stowed: 2.6 in.
• Length, deployed: 1.5 in.

NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.

Not overly impressed.
I had to file the front sight down to get it to function properly. Not the best BUS but you get what you pay for.

Magpul works. Low profile. Good go to back up.

These sites are bomb proof and work. Given these positive remarks, they are a bit bulky. Otherwise a great investment.
