Ammo: PMC 55 gr ,Fed XM-193,and WW-Q3131.
100 yrds
First the Sig. awesome smooth ,almost no felt recoil ejection was aggressive with cases landing 15-20 feet away but both foreward and back in a 90 degree fan shape. best group was with the XM-193 @ 2.5". PMC came in second @ 3". My verision is the original model but I replaced the fishgill handgaurds with a set of classic's. I'm going to upgrade the sights with the dioper style SOON. The Sig holo sight seemed a little cheesey but worked as needed. I didn't put any other optic's on and am 100% positive group size would shrink with a quality scope like a XTR burris or Trijicon TR-21.
XCR,
After dialing the gas setting down from 4 to 2 the felt recoil decreased but was still more than an AR or the Sig. For some reason the Win Q-3131 shot the best with this one and I actually had a 1.5" 3 shot group with Irons. Ejection was more AR like with cases going foreward and to the right 5-7 feet. Further on the higher gas setting. Most groups hovered around the 3.5" range and the MI folding sights are not optimal but should be considered as they were designed as Back up sights. Again this rifle would benifit from a better optic than my Aimpoint. Using P-Mags , C-Products 30's and D&H I expiranced 0 malfunctions in 300 rds through both rifles and would consider both to be exceptional alternitaves to an AR. The ergonomics on the XCR are superior to the Sig with its left side charging handle ,ambi bolt catch,and short throw selector lever.
The trigger on the Sig was the better trigger though.
