Pretty good! - Weaver AR-15/M16 Flat Top Riser Rifle Rail Mount

Pretty much a neccessity of you want to mount a traditional style scope on your AR flat top. It allows the user to have far better options for eye relief than mounting it straight on the upper receiver. If you have QD rings (I have Leupold rings), I would reccomend getting the additional screw set as it would make for a far cleaner install on your AR upper.
Pros: Easy to install, leaves room for BUIS on the receiver, allows you to locate the scope forward for better eye clearance and easier access to the charging handle.
Cons: QD levers are a little strange to install. Why does the additional non QD screws cost extra?
