Last I tried, Daisy still has them. There's more needed to use the clips in an 853 than just the receiver, though.DAISY 853C PART NUMBERS THAT DIFFER FROM THE 853 1. 137922-000 Receiver ($6.00)2. 168532-000 Pump lever assembly ($11.00)3. 169311-000 Valve body and barrel (costs $60.00)4. 154062-100 Sear ($1.00)5. 135547-000 Hammer ($2.50)6. 169746-K00 Bolt assembly ($2.50)7. 154148-100 Actuator bar rotator ($1.00)8. 154059-100 Bar actuator ($2.00)9. 163119-000 clips (5 for $4.95)10. 154061-000 Single shot adapter ($1.00)
The valve body/barrel is expensive but shouldn't hurt power. Don't know if the 853C has a dished piston. If it does I'd first try reusing the 853 pump lever assembly.
IMHO the easiest way for the energy/MV to be lowered would be to dish the piston. If that's the case, easy fix. I'd want to verify that, though. Might take a look around the Canadian forums, one is: https://www.airgunforum.ca/forums/viewforum.php?f=25&start=
I to had problems with loading pellets in my Daisy 880 after i put scope on it.Have a SE 509TW cross lock tweezers with 45 degree angle. Squeeze the middleand it opens up. Grab pellet between head and skirt. Then drop pellet in loading gate.Maybe about 2 seconds. They sell for about $5.00. No more fumbling with pellets.
I hear some guys suggesting pellet pens. I'm not a fan of pellet pens. They don't work well for me in these side and top loaders either.
