Well I love the 715T but the bolt would randomly lock back every 20 shots or so. I watched videos of how people "thought" they fixed it lol.
So I finally pulled mine apart.....what a pain. Once apart, I looked at the bolt and handle assembly. I saw right away what was wrong, the bolt lock back system was poorly made and it's not really advertised as having one anyways. So I took the hook off the bolt handle and filed a ramp where the new square edge is from removing the hook. She works flawlessly now!
