  1. I have promising results so far with the Frontier 121 gr FP in my 16" CMMG. These have a slightly thicker copper coating and are somewhere in between plated and jacketed. I have yet to test N320 vs N340 with this bullet. The plan for me is to settle on the most accurate load and then fine tune the buffer system for it. My CMMG is very picky with bullets and very few have acceptable accuracy.... Over 3 inches groups at 25 meters is not uncommon with bullets it doesn't like.
  2. Also consider if you really want to time the comp to be straight on the barrel or if you want to time the comp so the recoil gets straight into the shoulder, or at least so the dot moves only vertically. I prefer the latter, that usually means having the comp between 1 and 2 o'clock for me (seen from behind). My comp has only upward ports and I'm right handed. If I would have the comp on straight then dot would move slightly sideways.
  3. I didn't. I compared the FOV on LOWEST magnification, since that is the only fair comparison. Also, at higher magnifications the FOV is just a factor of the FOV at 1x. What I was saying is that the FOV of the Vortex 1-10x at 1x is not too great, compared to Swarovski z8i 1-8x or z6i 1-6i, Kahles 1-6x, Zeiss 1-6x or Ultimax 1-6x etc. And I think a wide FOV and a big eye box are bigger factors for IPSC and 3-gun than 6x, 8x, or 10x max magnification, as fast target aquisition trumps zoom when it comes to scores. That said, I'm going for the scope with the highest magnification without comprimising on FOV, which currently is 8x in Swarovski or Zeiss variety - Swaro having the advantage of better reticle (BRT). Looking forward to the day when 1-10x scopes comes with similar FOV as the z8i.
  4. I have a CMMG Guard. Mixed impressions. The radially delayed blowback bolt is great. The fit of the CMMG upper and lower is terrible, however, and the feel of the rifle suffers because of it. The rifle cycles flawlessly even though I have tuned the buffer system plenty. My CMMG barrel is also very picky with bullets and ammo, short throat and very few bullets are accurate through it. If I'd do it all over again I'd do a build with QC10 upper and lower with CMMG radially delayed bolt. Also curious if the CMMG bolt works in the JP.
  5. Field of view was not too great, an important factor for fast target aquisition. About the same FOV as the March 1-10x24, but the March is more than 2 oz lighter. Vortex is a bit cheaper, though. I'll stay with my Swaro Z8i 1-8x24.
  6. OK, I'll take a guess. Hydraulic dampening in both ends of the buffer? So it softens both the impulse of hitting the stock AND going back into battery. Smart to make it light. Easier to add a weight, than to remove.
  7. Same as always. Proper technique does the biggest difference. Heavier buffer weight and stronger spring, for such powerful loads I would go the Blitzkrieg 5015HD with the extra weight, as short stroke as possible and a strong spring like 308 JP, Tubbs flat 308 or red Sprinco, maybe sth even stronger. A comp will provide the last touch. I prefer upward vents only to give flatness rather than softness. And 163 PF is not so bad. In my 16" CMMG the most accurate factory ammo (in my rifle) , Geco 124 gr, does 156 PF and is still very managable. Not much difference from my 140 PF hand loads. In my rifle I'm going with the most accurate load and tuning the rifle for it. Recoil is not so much a factor in rifle as with pistols.
  8. They look awesome. Brilliant to combine the heavy frame from Stock III with the bull barrel and lighter slide of the Limited Custom. Should shoot very flat! Would like one milled for optics. Only downside is that they are only availible in the US for now.
  9. http://blackdogmachinellc.net/ Hoping this will prove reliable and good for PCC. Higher capacity without having 20 inches of magazine sticking out of the gun would be great!
  10. My screw is long gone. I glue the sight in place with epoxy. Need to heat the sight to remove it, but it doesn't come loose unless I want it to.
  11. No, the z8i 1-8x is SFP. I have one, with BRT reticle.
  12. Aimpoint ACRO is the new kid on the block. Possibly the new king of reliability, time will tell... I'm getting one for my Walther Q4.
  13. tomv, that doesn't look like any magpul grip i can find in their catalog. Can you double check what it is exactly? It looks nice and I'd be interested to buy and try. https://www.magpul.com/firearms-accessories/grips/see-all
  14. On my CMMG with Hiperfire trigger, the hammer resets way before the bolt has traveled enough to be able to load the next round, so check this also. I set mine so the bolt can travel past the magazine and then some.
  15. The rifle below is my PCC, a 16" CMMG MkGs Resolute 200 that I have upgraded and made to be as similar as my AR15 (above) as possible. Upgrades include Hiperfire Eclipse trigger, Taccom ULW compensator, Aero S-one handguard, Magpul MOE SL stock, BCM carbine buffer tube, Magpul MOE K2 grip, Kynshot 5004 buffer and JP 308 carbine spring. Short-stroked, of course. Shots soft, fast and reliably. Quite unimpressed about the tolerances in the CMMG reciever and lower, though. Needed JP oversize takedown pins and a rubber thingamajig to be quiet from rattle.
