Took my daughter to the range the other evening, first time we've been able to go in a while. Fun was had and our carbon footprints suitably enlarged. I took the Carbine along just to check zero.
And why is that, you ask, since I'd only zeroed it about a week ago? Because I had it leaned in what I THOUGHT was a secure position a couple of days ago(always had been before, dammit) and it slid off and fell. Right on the Millett. Which I think caused some of the paint to blister a touch from my language.
If the thing shifted at all, I couldn't tell. It put the rounds right where I was aiming. I'm liking this sight more and more.
More Carbine stuff
The CMP M1 Carbine page has links to two good articles, one on Carbine shooting with accuracy (covers fitting barrel/receiver to stock & barrel band, ammo and such) and- if you're looking for some- THE article on the Carbine 30-round magazine.
The ammo pouches for the older 20-round M16 magazines will very nicely hold four of the 30-round Carbine magazines.
And now, I'm to bed. Night, all.
