For sale, my custom M4 recoil. This started as a Bolt BR4 however I changed out the front handguard for a 12" key mod handguard putting in a longer 6.03mm tight bore barrel. 

Internally its pretty much stock, apart from the barrel, and a madbull shark hop rubber and bucking. I also converted to a Deans connector and my soldering iron slipped so the plastic looks a little singed but functions fine. 

Shoots well, the recoil is probably the strongest I've ever had on a airsoft gun.

This gun comes from me having a DMR thsn kept forgetting to transition to my side arm when in a building. So I wanted something with long range within my sites FPS limits so I can use it up close and personal. 

BOLT Airsoft recommends using a 11.1v lipo however I've found over the years that these have a nasty habit of shredding gearboxes. So I will be including an essentially new 7.4v with this gun. 

Videos of it firing are available on request. 

Price includes P&P
