510 indexing post / mag clip problems

Sat Sep 22, 2018 1:58 pm

Just of late I've had a few problems with indexing the mag , I put a new post in, which works 90% of the time, but doesn't spin the mag every so often . Also today (first time out with new index post) it started 'spitting' the mag out. It improved a bit over the mornings shooting, but is still doing it on an intermittent basis. It was suggested to bend the mag clip down a little bit to help hold the mag in. This did help a bit but it is still both missing an index and spitting the mag out every so often . Any ideas ..thanks.

The magazine should click into place as the mag engages the retaining clip. If it wont then clean the crud from under the clip and see if it also needs adjusting.
Is the spring an original as there are some rogue ones that use a heavier spring steel and its then counter productive.
The magazine should be easy to rotate and a little clean and spray lube can pay dividends.
A neat trick is to remove a coil from the original spring as the ball bearing sits too heavy in the grooves. If you do this mod please do it in a clear plastic bag to prevent the bearing from flying into the air and being lost :o .
The magazine spring sometimes needs slightly bending back into shape and can only be done by looking at the spring when you pull the lever.

I hope these few pointers help

Air Arms have modified the index post - it looks completely different now - I would fit that for starters.
Best ask the Factory where to get one as I guess there are a lot of the old ones out there !
