Even if you have a high-quality optic or scope on your rifle, it is important to have a set of back up iron sights (BUIS) mounted to your receiver and rail just in case your optic fails. The Leapers Accu-Sync spring-loaded flip-up front sight is designed to stay out of the way when you don’t need it and quickly deployable when you do. It is precision machined from aluminum and features a matte black finish so you can be sure it won’t break or rust in harsh conditions. This back up sight has a spring-loaded function that is activated by a positive lock push button. When depressed the sight is locked in the upright position to keep it from collapsing during use. The A2 front sight post is elevation adjustable and can be replaced with aftermarket Mil-Spec sight posts. The low-profile sight base attaches to 1913 picatinny rails and features integral recoil stops and a Torx screw locking mechanism to ensure a secure return to zero. Ensure your AR-15 or AR-10 will keep you in the fight with this back up front iron sight.

Great sights at a super price!

I already have 4 sets of Leapers/UTG backup sights. I like them better than any of the other backup sights I've seen that are 2 or 3 times as expensive. The sights I just received look to be even better than the previous models. Thank you, UTG, I have yet to come across any of your items that has disappointed!

Great irons for great price!!

I have the front and rear combo of these buis and all I can say is they are great!! Owning a set of magpul pro irons I pick these over the magpul!! They are cheaper and better so if your looking go ahead and buy it!!

Bought this to pair with the matching rear buis on a 9 mm AR. Unfortunately, this one is defective as it keeps popping up on its own after about 3 rounds. I push it back down and 3-4 rounds later it pops up again. Very annoying/ I have a pair of these that function perfectly as does the rear sight that I had on hand. I thing it's poor QC on the part of UTG.

Great value


Got a set of these for an AR pistol. I like how compact they are. Impressed with the quality. Looking to get another set soon.
