I won this flat top ar 15 from Safeside Tactical,never heard of them until I saw the contest posted.They are based in Vinton Virginia.Today I added a quad rail and pistol grip.The light may not stay.I ordered a rail mount sling adapter today so I can use a 2 point sling.There is a cable with a quick connect on the buffer tube for a 1 point sling.This is actually a very nice rifle,well built and tight specs.I forgot to mention that I put a BSA red dot scope on it,I know it's not a top of the line scope but this rifle will be for range and home defense,it's not like I'm going into battle with it.Anyway I'm generally pleased with it and it will outlast me.Did I mention that I won it?
