Ncstar tactical red laser sight w/ universal tir-rail barrell mount - NcSTAR Tactical Red Laser Rifle Sight w/ Universal Tri-Rail Barrel Mount

Reasonable price,esay to install and sight in. Good to about 20 yards then red dot increases in size. Should use care when installing. Too many turns when mounting will crack aluminum alloy. Over all a real good deal.
Pros: Priced right, Easy to install, Easy sighting Adjustment
Cons: Be careful when installing, aluminum alloy will crack
