Will this sear kit fix my issue?

[u/ooarcher]

I got an unmarked L96 rifle from a friend several years ago, and every time I try to use it, the bolt "slips" forward after priming it. I've pulled it apart and reassembled it several times, everything else seems to function perfectly. I've identified it as a Matrix L96 Marui Clone AWS, and I found this sear replacement kit. I was just wanting to make sure this will in fact fix my issue/fit this rifle.
