Here’s your answer for the adaptability of an M4 with the body of somethIng RARE. I’ll have a full list of perk and upgrades once I find the email from wolverine Airsoft of the initial order but here’s what I can tell you it has. 5 mags including original PTS mag Filtered line Original packaging from paperwork to box Mock silencer 14” tbb Holo sight Extended and original grip R-hoped altered hop up unit Hydra gen2 with pdr cradle And ccw to cow extra external barrel attachment If you have ANY questions feel free to ask. I love this gun just for its use and adaptability in CQB indoors to long range engagements. I’ve feuded it for 5 games and every time it turns heads. I’ve even won unique contests with this sucker haha. Thanks for looking everyone, wish y’all the best!
