Well I picked up a used RRA ar15 Monday and took it out for the 1st time today. First thing 223 ammo is hard to find where I live I ended up buying 2 boxes of PMC bronze and 1 box of cheap steel case Precision Ammunition. I cleaned and oiled it yesterday and today I took it out and sighted the iron sights in at 50yds. It took me 16 shoots to sight it in and now I am good out to 75 yds.... Could do better hopefully next time... Now using the scoop witch was basically already sighted in I was hitting 1 gallon water jugs at 150yds and at 200 yds... It took about 3 shoots each to hit but man I can not believe I did, I just never thought I could not me a pistol guy. ok not all went perfect I am not sure why but I had many failure to extract with the brass pmc ammo like 6 times and it was $10 a box but on the other hand the cheap $6 a box steel case stuff worked flawlessly? I opened it up with the last mag with the cheap stuff. All in all I had a great time and I will keep my $500 AR15 I'm hooked. I will find out the problem with the failure to extract the brass maybe I need to clean it better. I have not shot a rifle in 8 years and I am happy with my results. I almost like shooting the AR more then my pistols and I think one more outing and I will like it more for a simple guy like me hitting a water jug at 200 yds with an AR feel great! Some day I hope to be like many of you reaching out to 400 and beyond.
