Description

FAST™ is a series of optic mounts and platforms that provide end users with a quicker sight picture than standard height mounts. A 2.26” optical centerline height provides faster/easier reticle acquisition while wearing electronic ear pro/communications headsets, night vision goggles and protective masks, and allows for more rapid visual processing of the battlefield by promoting a heads-up posture. A heads-up posture also helps users maintain a neutral spine position which is more comfortable while wearing helmets, plate carriers and other heavy gear.

    • Rifle mount
Perfect height when paired with my EO TECH EXPS mounted on my Daniel Defense ar-15. Seems very durable so far and installs easily.

    • If you need to raise you dot this is the raiser for you!
Great quality at an awesome price. Needed to raise my red dot up on a 22lr. The mount easily and torqued to specs. Have had no trouble with the mounting bracket becoming loose.

    • If you have the unity riser for the G33 Magnifier, This is the correct riser.
It was shipped well and product was not damaged and it was perfect condition and no sign of it being a counterfeit. The Box was also has seal tape so i know its not opened at all either. And the box and sticker seal that came with it looked exactly what i purchased from my local gun store. [the riser that i bought that was the wrong version] Story and why i bought it: I have holosun laser i want to put on top of handguard [so the laser perfectly aligns from both close to far range] but it blocked my FOV of the EO Tech and also wanted a magnifier. I found that there was two different risers and one is specifically matches for the Magnifier, and this (Absolute Riser in this product page) is the correct version. "The Absolute Riser" is the specific riser that goes with the Unity magnifier [the one that does up and down]. Using this one I was able to have my full FOV of my EO Tech with a magnifier, and the laser no longer blocking my optic. And by then you should have a perfect room clearing in the dark CQB to midrange build to use like i did. ... show more
