When you buy the front you gotta get the rear especially at these prices I wouldn’t buy anywhere else.
Good quality sight but over priced.
Exactly as described and sale price made it a better buy than other lower priced sights of questionable quality. Needed this for a Dissipator upper (carbine barrel with rifle-length sight radius) and works fine. SKD lightning shipping a bonus!
SKD's shipping was quick as usual. The sight was an extremely tight fit on the rail, had to be hammered forward (I tapped it forward with the handle of my multitool) to slide into place. Very good quality composite, screw fastens it into place. Very sturdy engineering. The flip up design decreases the sight radius (maybe 1") but it's only a backup for an optic anyway. The ergonomics are very good, sight can be flipped up just with a thumb toggle, without taking a hand off the grip. Sight is flipped back down quickly and locks back into place automatically.
Mounted the back up sight and it was dead on. No adjustment necessary. Thanks Magpul. SKD shipping was awesome as usual. Ordered on Wednesday and received on Saturday.
Can't say it enough, best backup sights for the money. GOt them in OD for my IWI Tavor. Also have in FDE them for my Stag Arms AR15-2T 🇺🇸
This is a great transition from a fixed sight to a flip down/up sight. And just the right price where you don't get junk and don't have to spend a fortune.
It's a good backup sight for the money.
As always, top notch Magpul kit!
