Well I pick up my PS 90 tri rail on Monday from my FFL. 1400.00 OTD. I will be sending for the free C-More. Any advice on sights or lasers would be great. What ammo works best. A good sling would be nice. I willbe buying 3-4 50 round mags looking at CMMG price wise. Thank you in advance for all you help and insight. My other toys are a tricked out colt 6721, Benelli M1014, Sig P228......
