For firearms with limited rail space or raised rails, the HTA MULTI base offers shooters a simple and compact method for installing back up iron sights. These bases will allow you to install nearly any Glock compatible iron sights (G17, 19, 22, etc.) directly onto a picatinny rail and only take up a few rail slots to accomplish it. With tall suppressor height sights, you'll be able to co-witness in the lower third on microdots like the RMR, Vortex Venom, AimPoint T2/H2 and Burris Fastfire. Just as importantly, you'll be able to select the type of sight you want to use, since most any Glock sight will work, whether it's adjustable tritium night sights or very affordable OEM polymer sights.
The applications and advantages for this type of low-profile, modular system are countless. Notably, this design is highly compact, conserving precious rail space for optics on short railed firearms like the PS90 and the Steyr AUG, which may not have enough room for full size flip up sights. Firearms that must be held like a traditional pistol, such as the Keltec P50, CZ Scorpion, and AR-15 pistols can also benefit from these sights, as peep sights may not be practical with arm's length eye relief. The super low profile of our MULTI Base puts them at a more natural height on firearms with traditional drop comb stocks like shotguns and also keeps the sight height over the bore axis to a minimum. This in turn means these sights hold elevation more consistently across various distances, especially at close range, than taller BUIS systems. Furthermore, in many applications and conditions, the speed and easy acquisition of pistol sights may be more desirable than peep sights or optical sights.
These are made in the USA from 4140 steel, bead blasted and finished in an anti-reflective mil-spec manganese phosphate. A pistol sight adjustment vice is recommended for installation and zeroing of the rear sight. A minimum height of about 1" above the cheek rest (if any) is required for proper line of sight.
Note: The most current HTA 90/22 model already includes a cut in the aluminum rail that allows for Glock sights to be installed. This item will not be needed on newer models and is intended for other firearms that require very compact sights. Some early model 90/22's also may not have the necessary cuts in the rail.
*Glock sights not included. 9/64" hex key required for installation.
