Okay I got a new piston today it's the red Laylax piston with 45° catch. When I cock it back it Kindaaa catches but not really so then I changed back pistons and it started slam firing. So if I get a new 45° sear will it work? Also can I get just the 2nd sear from pdi or do I need to get both 1st and second? edit: i have a jg bar 10 everything stock but the piston and an 140 or 150 spring.
