I got a TC Renegade flintlock and it had the early lock with poor geometry. All they changed is the ****. The **** that is on there can be reforged to work satisfactory or what I will eventually do is just replace the whole lock with a better option. The cool thing with most of TC stuff is you can swap out barrels really easily. I hand forged the ****, rehardened the frizzen, and slapped a French amber flint on there and it sparks as good as a cheap mass produced lock is going to spark.
