thompson does replace the frizzen if you buy the hawkins.but they dont last,they get grooves in it that catch the flint.RMC SPORTS which is 30 miles from me has extra hard ones.they are great but expensive.22 dollars.warranty on hawkins is great.i had lock problem 30 years old hawkin and they replaced it free.also i had them tune the barrel while it was there.they have a way of checking it for accurate.all freee, then they gave me new frizzen too.i like thompson very much.
