Tough sight - Atibal AT-MCRD PRO Micro Red Dot Sight

I own 4 atibal sights. 3 MRDS. MRDV1 was the first. I've shot thousands of rounds with this sight on a competition AR and have beat the sheit out of it. It has held up to the punishment its been put through. Also have 2 MRDV2, one on a 9mm pcc (also had sheit beat out of it) and another MRDV2 on a 300 blk. Have been pleased with all of them. The latest red dot set atop keltec 40 cal pcc. Haven't had the chance to test it in match setting yet. Would recommend all, just wished MRDV2 had the sight cover like the V1 does. Over all very good TOUGH sights.
