I took my SWaMPy AR-15 Sport to the range for the first time this afternoon. FYI 25 meters equals 82 feet and 1/4 inch.
Lessons learned:
My 64 year old eyes did NOT like the small peep sight, I went to the large ghost ring.
I was a much better shot when I was 22, despite the web gear and jumping in and out of a hole.
25 meters is a lot longer now days.
I kept all my shots on the standard 8.5 x 11 paper, on which I printed the standard 25 meter zero target.
I did not put the required five rounds into the circle..we have high standards here in FL. I did manage two out of three, but my breathing needs work.
I really need an optic...now which one.
The A2 style grip is skinny as described.
I had to get back into the rhythm of AR procedure, it took about 5, 3 shot groups.
The factory sights work well enough as installed, but I couldn't tighten the groups up enough to feel good about the 300 meter shot, much less the 460.

Who is very pleased and looking for a new more AR carbine case. The Sport is 33" long with the stock closed.
