Boom, as for the "steel" Wolf brand of ammo, it does have a polymer coating, but the problem comes when the chamber gets really hot. And that happens very quickly in such rifles. In fact if you rattle off 20 rounds or more, the barrel will be so hot, you won't be able to touch it...believe that! I've had to literally wait until the rifle barrel cooled off a little to but them in their gun cases to come back home. And when the chamber does get hot, it starts melting that polymer coating and starts sticking and creates lockup issues. And because AR's are built to way tighter standards then AKs, it will create those type problems. So you can shoot whatever you want, but just be prepared for heat issues with cheap ammo, steel being the worst manufactured. And then IF you decide to reload, make certain you get brass cases with BOXER type primers, or you will have a lot of work ahead of you to try and reload the spent rounds. I do speak from lots of experience. JMHO!
As for mounting any type rear sight, the closer to the barrel center line the more accurate it will shoot at all distances. The higher the sight or scope is mounted from the barrel centerline the more angled the sight and bullet will be to each other. Example, if you mount a scope with the "See-through mounts" that were very popular back a few years, the only place the sight and bullet will be the same, is at the sight-in distance. Targets before that distance will have bullet impacts high, and likewise the further the distance from the sight-in it will be lower.
I do remember one opening morning hunt me and two other guys were on. As luck would have it, I climbed up in my 16' ladder-stand and as soon as I turned around and sat down, I see a 7 point buck at the base of the ladder. He must have smelled the doe scent I used on the trail into the stand. :noidea: So I had "See-through mounts" on my rifle and I aimed the cross-hairs at the heart area of the deer. This was nearly straight down, just a slight angle from 90 degrees, and so the scope was positioned at the heart, BUT the barrel centerline trajectory was a heck of a lot lower. I shot and the deer ran off. Of course the two other guys came as soon as they hear the report and we started looking for that deer. We looked for a few hours, finding blood at a few spots. And finely we found that buck. The bullet just hit very low and hit one lung. So because of the angle of the see-through mount/scope to the barrel centerline, I nearly miss that deer altogether. I true lesson learned about sight angles and barrel centerline. So lower mounts, be it open sights or scope mount is always better. The deviation is so much less that way. And no more See-through mounts ever again for me now. JMHO!
