Yeah,
A softnose bolt is a great upgrade anyway, even if you arent using a halo.
Ram stroke is easy when you have the angel toolset.
Heres how we do it:
Air up the gun. Turn the ram stroke forward (clockwise) until you cant open the breach anymore, then turn it back a quarter turn or so (making sure you can open the breach)
If you are getting Tom to do you double detents then yeah that should work!
You need to grease the drivebelt quite heavily the first time you do it, then you just need a tiny bit, every few months.
With fresh, good quality paint, it should be fine!
