Another vote for DPMS. Bought the AP4 last year, and it will shoot under MOA with Varget over 168 AMAX. Completely reliable also.

Thanks, I look forward to hearing the results.

Thanks for the info, Henning. I would have thought more people had tried the .22 upper. I know it doesn't simulate recoil, but it sure seems like I could save alot on ammo by doing a good bit of training with the 22. I may go ahead and get one and see if I can fix it to where it's not a jamamatic.

Does anyone know if the Witness 22 conversions will work, or can be made to work on the Elite Match guns?

I shoot nothing but the 168 AMAX in my DPMS carbine. I put it over 41.7 grn of Varget to an OAL of 2.800. IF I do my part it will shoot .5 MOA, I also crimp it with a Lee Factory Crimp. Also, use it for deer hunting and am very satisfied with it's performance on a live target as well as paper.

Thanks for the info, I just didn't want to beat my frame apart.

I'm hoping someone here can help. I have a Witness Elite Match in 40 S&W. My question is, should I replace the factory spring with something lighter, if so, how much lighter. I used to shoot bullseye and we used seperate springs for different loads. I'm sure this isn't much different, I just don't now what the limitations of the gun is, nor what is safe. I don't want to beat my gun to death by using to light of a spring. These are the loads I'm using. Thanks for the help. I use a minor load of 3.5 titegroup 180 grn xtp 1.135 major load 4.2 titegroup 180 grn xtp 1.180
