I had a stock Henry Big Boy X chambered in 44 mag. I contacted Lenny Marraffino of Spud9 Gunworks to do a tactical upgrade to my rifle. Larry was a pleasure to work with, repsonds quickly to inquiries, provide plenty of options and had very quick turn around time. His work was outstanding and his prices reasonable. He kept me up to date on all phases of the build. The resulting build is exceptional. Check out the result.
