Woo - Hooo!!!!
The welded Op Arm is working fine

. I put about 40rds through it this morning and the gun operated flawlessly.
Accuracy wasn' t too great (due to some stock fitting issues), but I now have full confidence in the gun' s operating system - at least for the short term anyway.
I' m still planning on replacing it as a hunting platform with something new though............maybe a Browning A-Bolt or a Savage 10FP-LE2 in .308.
