Realised I've been chiming in here without any show and tell, so here's my MWS... ("there are many like it, but this one is mine").
Internals:
Angry Gun Super Recoil buffer kit (high speed version)
DP enhanced nozzle spring set
SixG Super Nub (obligatory!)
UAC enhanced sealing buffer
DP aluminium lightweight bolt carrier (I highly recommend this; noticeably improves gas efficiency and cycle rate)
Angry Gun ambi charging handle
Angry Gun steel bolt stop plate (combines well with the aluminium bolt carrier)
Angry Gun Mil-Spec aluminium buffer tube
UAC Match trigger
...all fitted and tested by John at Fire Support (top bloke). Also tried to fit a WIITECH hardened steel disconnector, but it played havoc with the trigger set up, so it got taken out. Just a word of caution if you're considering one yourself.
Externals:
Mapul foregrip and rail covers
'Blagpul' stock
Vortex Spark red dot
I run it on Abbey Predator Ultra Gas using .28 indoor and .32 outdoor. Snappy as hell and shoots like a laser. Lurv it ❤️
