The Monstrum Shrapnel Offset Riser mount offers the same rock solid performance as the rest of our riser mount line, but with 2.5 inches of forward extension for more flexible optic placement and eye relief positioning. The picatinny base measures 2.5 inches (or 5 picatinny slots) in length while the top rail measures 5.5 inches (13 total picatinny slots). The rail extends an extra 2.5 inches over the front of the base, allowing for more forward positioning of long eye relief optics.
Available in high and low profile versions. The high profile mount provides 0.88 inches of rise over the receiver rail. The low profile mount provides 0.38 inches of rise.
The Picatinny base is equipped with custom recoil stop bolts that slot seamlessly into your Picatinny rail with zero wiggle - guaranteed to hold zero against the toughest of recoil.
The single piece machined 6061 grade aluminum profile is designed to shave off precious ounces of weight.
Uses hardened steel Torx mounting hardware to prevent stripping of the bolts.
All Monstrum mount and accessory products come with a lifetime warranty.

I recently added this Picatinny offset riser attachment to my rifle, and it’s made a huge difference in the comfort and performance of my setup. I used it to bring my ACOG optic to a more comfortable shooting position, and it worked perfectly.One feature I really appreciate is the 3 fastener mounting system, which provides excellent stability. There’s no wobble or shifting, even after repeated use at the range. The attachment feels solid and reliable, giving me confidence in its durability.Overall, this riser was a great upgrade. If you’re looking for a way to fine-tune your optic placement, I highly recommend this for both comfort and stability.

They feel well made, they're a little overpriced for what they are and I got 2 and put them in line with eachother but they don't line up exactly. If I remember I'll post pictures.

Good machining and it fits nice. I'm using it to install a scope on an old-fashioned muzzleloader. Does the trick.

This is the right addition to your AR 15 to raise the scope up and forward for a real comfortable and required eye relief needed for most scopes---
