Retail value 800+ selling for 550 This is my built full metal Echo1 SOB1 MP5 SSG, quite a mouth full 😂 This is probably my favorite variety of the mp5 because of its full metal design and in particular the charging handle. Due to the full metal design, it sounds like a real steel mp5 when racking it. Lots of metallic clacking noises, absolutely addictive. Hasn’t been fielded yet, only tested in the backyard. Mainly a trigger response build since my field doesn’t allow burst or full auto. Shoots 300-305fps with a .25 and 25rps. Trigger is spam-able like a Polarstar, it won’t lock up. Will come with the gun exactly as shown (reddot and suppressor), 3x 130rd midcaps and 3x metal hi caps Internals: T238 mostet v1.9 (picture shows old v1.42) wired to rear Echo 1 shell SHS 22TPA motor SHS 16:1 gear set short stroke 4 teeth Echo 1 v3 metal bearing spring guide Echo 1 7mm bearings SHS M110 spring Cyma poly steel rack piston Aluminum bearing piston head Cyma poly cylinder head Poly nozzle with o-ring Echo 1 type 2 cylinder
