Tech Bundle. All kinds of good parts here, a bunch of SHS pieces, mushroom style “silent” piston/cylinder head, buckings, barrels, springs, body pins, hop up units, tappet plates, v2/v3, m4 ak and mp5k parts, grips, heat sinks, motors, triggers, spring guides, etc and more. Good spares to fix a gun on game day or for cheap repairs. This collection has kept my guns going for years. I’m getting out of the sport so someone else take them before I throw them away.
