Arnette Knives and Arms will do them for OSA'ers for $10.00, We are at 750 Cherokee St. in catoosa, That is at the N.M. corner of Pine and Hiway 66. 918-695-3808.
OPS moved all of their firearms business down the street to the new 2A Shooting Center just West of Admiral/Yale.
2A is a kick-ass place that was certainly long overdue here in T-Town!
I'm sure the transfers are still applicable....just go down there and talk to Eric Fuson.
