I prefer lightweight, but it doesn't matter whether it's A-1,2, or 3.
My 20" is heavy, the handguards wobble a little bit, but it's a solid gun.
Definitely used with scratches, but nothing that affects function.
I'm not sure of the brand, but it's a good one. I can provide pictures and am planning on throwing some money or mags in on my end to make it a fair deal, if necessary.
I'm currently living in Ogden, UT, but will be living in Seattle,WA in a month or 2.
I have limited internet access, so it might be a couple days (no more than 4) before you hear back from me.
I'm also willing to straight up sell it, or do a partial trade for a 9mm handgun.
