Stripdown Bsa lightening GRT ?

[Marc of France]

Hi

I have just acquired a bsa and I want to do a service. Who has already dismantled this rifle ? The GRT system is special for remove the pin with 2 holes.

Thx for your help.

To remove the large spring pin, you need to make a tool that goes inside the tube but either side of the pin. Then compress the spring till the pin slips out.

A description of the tool


Wood or metal .
25mm diameter
60mm long
14mm slot cut in the end to slip down the sides of the pin.

There was a post not long back for another rifle that had the same set up and video shows how to remove the pin but the rest may be different to the BSA.
