Need to sell quickly! I’ve dropped the price on my Echo 1 Platinum M4 Custom. It’s worth around $650-$750, but I’m asking $400 for it and it’s pretty firm, but I’ll also entertain trades. Just shoot me an offer. Buyer most likely pays shipping, can negotiate. Basically, I just don’t have enough tech experience with gearboxes to get this working. I purchased the Platinum several years ago and it’s been an awesome gun, but recently decided to upgrade it. All in all, I purchased about $600 in internal and external upgrades. Before I got into the gearbox, I installed the prometheus inner barrel and the MAXX hopup chamber in combo with Maple Leaf bucking and tensioner nub and it shot LASER BEAMS… Seriously, even with the original stock spring and OG inner barrel, it was surprisingly accurate and far. I just realized that I don’t have the experience needed to get this up and running; and also don’t have the extra cash to take it to a tech. There are a few minor repairs to make, but someone with experience should be able to get this working like a dream. It just needs some basic wire crimping, new motor metal connectors, one body pin and maybe a new delta ring. From my understanding, it needs to be shimmed, the bearings set, and then obviously just putting the thing back together correctly. Here’s the list of upgrades/parts, plus the condition and retail cost… 552 Holo Graphic Sight Clone (red/green - adjustable brightness : $50 - Opened, never fielded Modify 8mm Ceramic Bearing Set - Super smooth - : $31.00 - In gearbox, but never used ZCI High Torque Neodymium Motor - Long : $30.00 - Opened, never used Prometheus Gearbox Shim Set : $6.00 - Opened, some are in the gearbox, some lost, and some in a baggie leftover Matrix CNC Machined Steel “Super High Torque” Gear Set (32:1) : $28.00 - Opened, never used Evike Silicone Grease : $$8.00 - Used Matrix Irregular Pitch M130 Spring : $10.00 - In gearbox, never used Prometheus 6.03 EG Tightbore Inner Barrel (455mm length) : $65.00 - Has had a few hundred high quality bb’s shot through it, but never fielded Matrix Fluted 10” CQB Outer Barrel (Black) $20.00 - On the gun, never fielded, will probably need a new delta ring MAXX Model CNC Aluminum HopUp Chamber (ME-PRO) : $59.00 - Installed, same as inner barrel, never fielded Matrix “Reloaded” High Performance Motor (Long - Balanced torque/speed) : $39.99 - Opened, never used Lonex Complete Internal Upgrade Series Enhanced Cylinder Set (POM vent type) : $ 45.00 - Installed, never used, but the aluminum nozzle tip is slightly bent Angel Custom “THOR II” CNC Aluminum Piston w/ CNC Steel Teeth : $30.00 - Installed, never used 8” Aluminum Suppressor w/ Both Adapters (cheap clone) - $15.00 - Fielded once, but neither adapters will tighten all the way, had to use electrical tape to work 1 Point Sling (Tan) : $5.00 - Fielded maybe 2x, great condition Maple Leaf Macaron Hop-Up Bucking (70) : $9.50 - Fielded once, in good condition Maple Leaf Omega Hop-Up Tensioner Nub : $6.99 - Fielded once, in good condition KWA K120 Midcap Magazines : $40 (x3) and $15 for the last one (Needs spring/catch replaced) - These were all fielded once, but had feeding issues due to fit (Mags work great, but needs velcro adjustment to get proper seal/seating in the mag well) Total for the upgrades/accessories: $587.00 I’m just trying to recoup the cost of the upgrades. I’ll include all remaining OG/stock parts along with the OG hard plastic carry case. I was originally hoping to get about $650-$750 out of this, but I understand that it’s going to need some minor repairs, a little tech work, and probably a Mosfet. However, I do believe that this will be an amazing build once assembled and working. I’m open to trades, preferably Novtritsch snipers, but also will entertain other guns (AEG’s, spring, and gas/CO2). I have plenty of pictures, just DM me for them or other questions.
