Test drive was today and what a gorgeous day it was to be out on the range!
I wanted to see how she cycled with different ammo so I brought out some AE black box, some Norinco, and some handloads (24.6gn varget iirc)
150 rounds later, only two hiccups - first was the very first round, bolt didn't go into battery. Second was one instance where the bolt didn't hold open on the last shot. Otherwise flawless.
I love the S&J comp, nice big fireball as seen on this screen grab
Even fully extended the stock is too short for me and it felt awkward initially. I let a few others shoot it and everyone seemed to find it a bit odd to shoulder, especially with the Sparc being mounted so low. But surprisingly, after a hundred rounds or so, it suddenly felt easy to point and reasonably comfortable; I wasn't expecting that.
The Cerakote held up well. A bit of scuffing on the stock from the charging handle and a few minor blemishes on the deflector from the brass but nothing unexpected. I know assembling an AR from scratch isn't exactly rocket science but I must say it is a good feeling when you do so and everything works the way it is supposed to!
