Just bolted back together, changed from muzzle mounted mod to overbarrell moderator lawrence precision,lighter profile Bartlien, than the Benchmark 22BR that i have taken off, 4" shorter in overall length , shaved about 300g with new contour and 34mm rings. Weight of rifle seems to more pointable ,ie less muzzle heavy . Just waiting for Lrr release in ultrashort 3x20x50 .Not drastic changes but better for intended purpose, ie vermin fox, Deer rosko π
