AR57 upper

I borrowed this AR57 upper (in 5.7x28mm) from a friend specifically for the amusement of certain friend’s daughters. Both of his girls are left-handed, so the upper that has next to no recoil and ejects down through the magazine well was just the right toy.
Because the rear rail on this upper is so short and because inserting magazines requires certain clearance, the compact Primary Arms prismatic 3x proved the best fit. For lack of room for a rear sight, I added a tiny CTC laser to the front rail instead in order to have some backup for close range. That rail is nowhere near the barrel, so heat isn’t an issue. The upper is pure blowback, so there’s no gas tube. I used a Cavalry Arms lower to reduce the weight.
I have some handloads with Barnes “varmint grenades” and samples from Elite Ammunition on the way, so we’ll find out how well it shoots next range trip.
The shooter shown is a wonderful example of successful home schooling. At 16, she has the demeanor rivaling the best-socialized adults. Working with her and her father was a rare pleasure.
