This started life as a PSA premium carbine with A2 profile, mid-length gas, 1/7 5.56 barrel. I upgraded it with: 1) Matech rear sight ($90) 2) tan/coyote A1 length solid stock/guards/grip ($135) 3) MS2 sling ($30) It has been shot very little and is mint/as new. The gun was $902.50 delivered (price at the time + sale, tax, transfer). Upgrades were as above so about $1,155 total. $750 sale ftf eastside of Seattle, ship actual cost elsewhere if desired.
