Picked up this G&P Magpul M4 with a locked up gearbox/trigger and missing stock and stock tube. Snagged it for 50 quid!
Completely stock but with Magpul receiver, Pistol grip, handguard and foregrip.
Do you guys think it's Foliage Green or Olive Drab? I am thinking the former myself.
Cracked it open, seems that the cocking lever spring has been overstretched so the bolt cover won't spring back as it should. The selector plate was broken in half.
One of the gearbox shell screws was overtightened and I had to drill it out.
In the gearbox I found the spur gear shaft completely sheared off and the motor pinion well worn. Replaced the spur gear, Air seal was OK, but I switched out the full cylinder for a 4/5ths as well as a new piston and cylinder head (which had to be modified to fit the gearbox protrusions)
Seems to be working OK if a little bit tight sounding.
Going to grab some parts from AK2M4 to get her really purring, as well as a stock tube and stock. The intention is to have a full set of M4A1 and Magpul furniture to switch between.
Parts list to purchase:
22TPA Neo motor
13:1 Gearset
V2 Selector plate
Replacement screws/springs
AOLS 363mm Barrel
Guarder Clear hop rubber
AR Latch
ZCI CNC steel Stock tube
Magpul PTS MOE Stock
M4A1 Stock
Parts acquired:
Perun Mosfet
Tokyo Marui M4A1 Kac style Handguard.
