Timney 313 on Arisaka Type 99 Sporter
This Timney trigger is great upgrade on the Arisaka Type 99. The directions have you file away material in the slot so that it will work. I thought I had taken enough out, but when I contacted Timney's Technicial Support (excellent by the way) they had me take out just a bit more and it works great now!!!
