Installed and tested comps today on Axis and 2 other rifles.
I bought 3 Witt machine comps and installed them on my axis 308 (which shoots very well) a 111 6.5 284 and a threaded muzzle 6.8 spc AR15. The comps are very well made and all fit the rifles on first try--though the axis comp was a tad tight. The only issue I ran into which I think bears mentioning is that care needs to be taken tightening the clamp-on screws--I broke one in half torquing it down tight--though I don't think I was putting all that much pressure on it.
Because it was raining on and off all day--all I could do was go to a nearby roadside clearcut an fire a few rounds through each just to see what the feeling was like.
The axis 308 seemed to have a recoil reduction which felt something on the order of 30 to 40 % shooting a 168 gr factory bullet; though the muzzle still tended to lift and I did not manage to keep the scope fixed on target when shooting free-hand. Next I fired my 6.5 284--which surprisingly seemed to have the most reduction in both recoil and muzzle lift--this surprised me cause it was firing magnum-like loads though the bullets were 130 gr 6.5. The 6.8 spc carbine seemed to have a recoil reduction on the order of what I got with the Axis--but I still couldn't keep the muzzle down to maintain sight picture through the shot. All shots were free-hand, not sure if that contributed to failure to keep the muzzle down (i.e. poor technique).
