i recently replaced the original loading bolt with a rowan engineering black one, it took a bit of heat,alot of pulling & a bit of up & down movement to get the original OFF,i came across 4 small dark coloured washer's on the floor, have they came from in innards of my s410,it loads & fires the pellet without any problem,i ain't got a clue where they came from, a little worried to say the least !!!!! ,can someone put my mind at rest.

What size, material are they

BBF

9mm in diameter, the hole is 4.5mm,they are dark steel.

The only washer I know of on an S410 is on the stock bolt, I've never seen any others

i think they are from something else, just seem's strange that i came across them when i did i've looked on CHAMBERS s400/s410 parts diagram, cant see anything on there.

I reckon, if it cocks , loads and fires, doubt that there's a problem.
But if it falls to bits, I was wrong
I'm pretty sure it's fine

I take it they are too large to have come with the Rowan handle? Do you have scope mounts or other fittings with M4 bolts?

if it shoots fine keep them safe .

mystery solved, the 4 washers were off a pair of sports match mounts,i ordered high sports match mounts & they were on them.so i presume they were also on the medium mount's.

You can always rely on Charlie to fix it f you are worried about them waskers ....
