Great light for AR-15 -- not for the Steyr AUG

I had no problem installing the light onto the AR-15 with its full length picatinny rail. I thought the supplied velcro was a poor way of attaching the pressure switch, so purchased the Magpul M-LOK Insight PEQ Tape Switch Mounting Plate, Part #: MAG631-BLK to attach the pressure switch to the handguard and it fit perfectly. The light appears to be of high quality so I purchased a second MK4 light for the Steyr AUG and found the rather large bolt used to attach the MK4 light onto the AUG's secondary picatinny rail was too large to mount the light. The bolt interferes with the primary picatinny rail, so my options are to either: - Remove the primary picatinny rail to gain clearance in order to install the light onto the secondary rail and then re-install the primary rail once the light has been installed - Locate a screw that does not have such a large bolt head - Purchase the PuP light mount kit which attaches to the AUG's gas block Have contacted Steiner Tech Support, they didn't have any suggestions re: mounting the pressure pad, (aside from adding more velcro) and they do not offer a screw with a smaller head so am disappointed with their support of the product.

About Steiner Mk4 Battle Light

The modular design of the 500 lumen Mk4 weapon light provides interchangeable switch options to meet a wide variety of battlefield needs. The low-profile design places the light close to the weapon body nearly eliminating the rifle barrel shadow and enhancing weapon handling switchology. The Mk4 can operate on two CR 123A batteries or one rechargeable Li-Ion battery (sold separately).
