AR-15/M16 FLATTOP RISER Reviews & Ratings

Machined aluminum riser clamps to flattop AR-15 receiver to position primary optic sights at eye level. Raises mounting height .750' to eliminate the need for extra-high rings in most applications. True, MIL-STD 1913 Picatinny cut accepts both Picatinny and Weaver-style rings. Two, easy-to-grip, slotted hex nuts accept a U.S. quarter for extra tightening leverage; full-length clamping bar locks riser securely to flattop receiver for zero movement even during harsh tactical operations. Precision CNC machined to ensure an exceptionally secure lock on the receiver rail. Smooth, curved front and rear contours on the underside provide a streamlined appearance, reduce weight, and minimize the chance of catching on gear. SPECS: 6061 T6 aluminum, hardcoat anodized, matte black. Approximately 5” (12.7cm) long, 1” (2.5cm) wide at the base, .975” (2.45cm) high overall. Adds .75” (1.9cm) to height of flattop. 4.8 oz. (136 g) weight.

Perfect!

Raises my scope just enough to be allow for a good cheek weld to the adjustable comb. Much more comfortable shooting after installation.

Best riser you can buy

Ordered this for my new DPMS G2 in 7.62 NATO. Very high quality and fine craftsmanship. Installed easily and was VERY secure with the 1/2 nuts that tighten it to the rail. Top of the line.

Excellent product

Easy to install. Just the right height for a 40mm objective lens on my flat top Rock River upper. In my opinion much more esthetic than high rings mounted on the rail.

AWESOME!!!

I wasn't sure what to expect since this item isn't from a "name brand". I was shocked and am not sending this back! I ordered two other risers (Yankee Hill and some other one) with plans to keep the best... I'm keeping this one. It perfectly co-witnesses my Bushnell Trophy TRS-25 red dot with my standard A2 post. The quick release screws on the side allow me to take this on/off without having to take off anything else. The YHM riser I ordered requires me to take off my rear sight to get it on/off. I like the option to use either a flat-head screw driver or a socket wrench to tighten/loosen the screws. The coloration and finish PERFECTLY matches my Stag AR and would expect it to match other makes as well. This item is durable and will not fall off. The screws are hardened and aren't likely to strip. Brownells did an EXCELLENT job with this!

Just right.

Great quality piece. Just what I was looking for. I am ordering more.

Beautiful!!

This riser fits like a glove, perfect for my S&W MP-15. Much lighter than the one it replaced. The perfect height for my sighting system. This is a very well made riser which adds a very business like appearence to my rifle. Would suggest this product to anyone looking for a riser.

Excellent Product

I ordered this riser to allow me to raise a Sig/Sauer red dot sight to proper eye level and to co-witness with my customer's backup sights. He could not find a riser that would do both until I suggested this product from Brownells. This riser gives just a tad more height than risers from other manufacturers and now the flip-up, rear backup sight made by Magpul co-witnesses perfectly. The AR-15 has a 16" M4 profile barrel with the standard mil-spec fixed front sight base. Additionally, the fit and finish of the riser are excellent and it looks bomb-proof. It also looks very business-like installed on the weapon. I highly recommend it.
