The Chop Shop Collection, topped by Classified skins
The Chop Shop Collection dates from May 2015 in CS:GO and is filed among the operation collections. The catalog links no case and no Souvenir Package to it, so its 16 skins are obtained by trading or through trade-up contracts inside the set.
The highest tier in Chop Shop is Classified, shared by Glock-18 | Twilight Galaxy and M4A1-S | Hot Rod. Both have short float ranges: the Glock-18 ends at 0.20, giving three wear levels, and the M4A1-S ends at 0.08, leaving only Factory New and Minimal Wear.
Two Restricted skins follow — Dual Berettas | Duelist, which covers the full 0.00–1.00 range, and SG 553 | Bulldozer, which runs from 0.06 to 0.80. Mil-Spec is the largest tier with five skins: CZ75-Auto | Emerald, Five-SeveN | Nitro, MAC-10 | Fade, MP7 | Full Stop and P250 | Whiteout. The Emerald and the Fade are both capped at 0.08.
Industrial Grade holds Desert Eagle | Night, Galil AR | Urban Rubble and USP-S | Para Green, and Consumer Grade closes with CZ75-Auto | Army Sheen, M249 | Impact Drill, MAG-7 | Seabird and SCAR-20 | Army Sheen. The two Army Sheen skins stop at 0.30, while Impact Drill and Seabird reach 1.00.
Half of the collection is pistols: eight skins, with two on the CZ75-Auto. Rifles take four slots, SMGs and heavy weapons two each, and 15 different weapons appear in total. StatTrak™ versions are absent from Chop Shop.
The cheapest current marketplace offer for M4A1-S | Hot Rod is $1 233.90 (Factory New), and for Glock-18 | Twilight Galaxy it is $424.70 (Factory New).
