RABIDFOX50 6 Posted October 23, 2010 Report Share Posted October 23, 2010 Now that I have the Chaos extended quad rail with the HK sights, I have been looking for an optic that would co-witness fairly well. The Primary Arms Gen7 red dot looks good in that it mounts very low on the rails. Would this work? Also, will the Magpul XTM rail covers work on the Chaos rails?

LowCapacity 3 Posted October 24, 2010 Report Share Posted October 24, 2010 I have the magpul rail covers on mine and they fit perfect. Don't know about the optics though. Quote Link to post Share on other sites

I would imagine any rail cover/ladder will work, the rail is 1913 mil-spec. On a related note, how many rail spaces is it, top bottom and sides? Mine arrived, but I'm out of town and would like to get the ball rolling on some ladders for it. Quote Link to post Share on other sites
RABIDFOX50 6 Posted October 24, 2010 Author Report Share Posted October 24, 2010 (edited) It's top bottom and sides. I did have a full ladder panel laying around and tried it. You can cover all but one notch with one ladder panel on the L/R sides and bottom. On the top you have seven notches exposed using one ladder panel if you have Cameron's HK sights installed as I do. So three would cover 90% of the rails. Maybe buy one more to cut up and use for the remaining notches. I have the magpul rail covers on mine and they fit perfect. Don't know about the optics though. Outstanding, thanks. Edited October 24, 2010 by RABIDFOX50 Quote Link to post Share on other sites

Just got home and installed my Chaos rail with sights, and it's great! I also took my Primary Arms RDS (Gen 1, but very similar to the Gen 7) off my Draco, and it co-witnesses on the S12. I'll be getting a Gen 7 soon as my Gen 1 has survive over 2500 rounds on my Draco! Edited October 30, 2010 by mammynun Quote Link to post Share on other sites

As a side note, I ordered some TXM covers and they do in fact fit the Chaos rail perfect. I'm ordering the Primary Arms Gen7 dt on Monday. Quote Link to post Share on other sites
