Should you need spare parts, I highly recommend
Blackpool Air Rifles from over in England as they stock all of the Daystate parts (including spare magazines and o-rings) and ship to the States. I purchased o-rings and some other bits and pieces from them before and they were awesome to deal with.
As for taking the breech block apart, I simply watched a couple YouTube videos to learn how to disassemble the breech block on my Wolf.
Here are two such videos that should be helpful for you:
Vid #1 - This shows Ernest Rowe taking apart the breech block on an Electronic Mk3 which is almost identical to the Airwolf. Watch from 1:14 onwards.
https://youtu.be/5HyrHW_CVMU Vid #2 - Some dude taking apart the breech block of an Air Ranger which is also very similar to the breech block on the Wolf.
Watch from 1:00 min onwards.
https://youtu.be/2sqhGPmm3MM You will need the following items:
- 2.5mm Allen key for the front bolts
- Flat head screw driver for the middle screws where the magazine sit
- 3/32" Allen key for the rear bolts. The rear bolts are staked and can be a pain.
- Cotton swabs to clean out any gunk build up and old grease
- Clean cotton rags or paper towels
- Silicone grease for o-rings
- Molly grease (apply a thin coat to the brass actuator to reduce friction and make cocking butter smooth)
- Ballistol or similar spray lubricant/cleaner (be careful around the transfer port).
- Loctite for the probe/bolt stop screw
Caution: be careful not to lose any small springs or ball bearings when removing set screws. There is a small ball bearing that sits between the probe and a set screw on top of the breach block towards the rear which is used to adjust tension on the bolt as well as keep the bolt in place as it sits in a small groove on the probe. I lost the ball bearing and spent an hour on my hands and knees combing through my carpet before finding it.
Good luck!
