Questions & Answers
Will this fit a Marlin 1895 45/70? Expert Answer

Threads out of tolerance. by Greg Anderson, Verified Owner, November 16, 2022

verry disappointing by Dakota Snell, Verified Owner, September 1, 2023
The treads on this brake were cut oversized and didnt fit. Both barrel and brake said they were 5/8 x 32 but when tightened down it stripped the tips of the threads off of my barrel and i could pull it rite off.
