Looks good. Looking forward to hearing more as you explore its capabilities.

Have you checked the case length? Sounds like you may be feeding rounds that are slightly too long for the chamber. Perhaps you are hitting the lands very hard with the chambered rounds? Maybe the bullet is seated too long? If fired extraction is also a problem then I lean more toward somehow the case being long from the start
And yes, the chambers on bolt guns can be much less sloppy than in an AR, especially if it's a true 5.56mm chamber (I think).
Somebody with more bolt gun expertise should be along shortly.

I have a QC10 lower with a Gibbs side charging upper. Runs flawlessly. If I shoot trooper this year, I'll run it. I used a CMMG setup the last two years using a VM Hytec block and UZI mags. It ran great also! I had a Geissele SD3G trigger and cheap Bushnell 1x on it. I was quad tapping spinners and spinning them quickly.
The most fun I've ever had at ANY match was when shooting my PCC at pistol targets. I recommend shooting trooper at least once. It's a blast! I might be shooting limited this year to take a little break from the 150lb load out
James,
Thank you. I had not heard of Gibbs before.

Buy a Colt 6951, install the trigger, furniture and sights of your choice and call it good.
Mick
That's been one to consider, yes. Thanks.
The JP GMR-13 and the Colt 6951 have been top contenders from what I had seen. Good to know others think the same.

Joe,
Thank you for your reply and thoughts on Trooper. I'm not that great a precision pistol shooter, so the PCC would be a bonus for me. Also, I think I'd like to own one generally, not only for the match. With that in mind, I think of it as more of a long-term investment. Being reliable for days in dust and heavy use at Ironman makes me think this will be a "buy once, cry once" type of PCC purchase. That's why I was considering either a full JP GMR-13 or at least a GMR upper. It has got to run and run hard.
EOtech is a great option for how my eyes work. I have one on my Open shotgun.
The unique challenge of Trooper appeals to me, but I will need time to gather all the materials and prepare myself.
Question to you:
Why the GMR upper on that particular lower? I've seen that others have done that. Was it for particular function, ergonomics, or cost?
Thanks again,
Mike

Some of you have seen my other post on longer range rifle for Ironman; likely for 2016.
So, I'm interested in seeing what a realistic and competitive gear set would be for that, even if I lose my senses and think about Trooper division. Looks like more competitive Trroper shooters use pistol carbines.
If you were going to Ironman to shoot Trooper. What Pistol Caliber Carbine (PCC) would you bring in 2016 and why?
Would you convert existing AR-16 receivers you have on hand?
Would you buy the new JP buy once and cry once?
What about a JP GMR upper on a QC10 lower?
Perhaps an entirely different solution?
And what about optics on top? 1x only (EOtech or Aimpoint styles)? Or a good 1-4x where we know it will live almost all the time at 1x with slight magnification dial up in a copuple of places.? (I have one handy, so I'm asking)
How "big" a feature is bolt hold open at the end of a magazine? I imagine it matters on the clock, but I haven't used a PCC before.
Yes, I'd need to train my body extensively for next year. Yes, I need to get in lots of shooting drills and practice. I understand all of that. However, I'm not well informed on the PCC market, so I'm asking for help.I shoot a M&P pistol in Open/Unlimited. I don't have any investment in Glock magazines.
Thanks in advance for not laughing me off the boards for this.
I'm also open to all sorts of Trooper recommendations big and small. If you think this thread isn't the best place then just message me directly with what you want to say.
Thank you again,
Mike

6 lbs 12 oz weight as pictured
Had to run upstairs to weigh so left blank initially
That is a VERY nice weight.
I was wondering if you had left it blank as a placeholder. Thank you.
-
How much does it weigh??
You said, "Overall without an optic as pictured the gun weighs" and then nothing
-
Mark, I read a lot of your posts and they are always very well written and full of information. Thank you for your contributions to this forum. I'm a "buy once cry once" kind of guy and I want the best/lightest carrier I can get but I also want a reliable/durable gun. What would you recommend for my application? Gun will be 18" rifle gas, SLR gas block, Jp silent captured spring.
Since ammunition type seemed to be part of the part wear situation, what ammunition are you planning to use? Really soft 55 grain 223? Some 75/77 grain BTHP match stuff? Other?

I'd rather at least have it made in a US ally than China. Maybe that sounds harsh, but I'd rather boost an ally's economy than China. We don't always have easy choices in some markets, I know. However in this case we have a few more options. That's just one opinion. Could be a nifty scope otherwise.
-
Sounds like you are in great hands with the advice. Please check back in the thread once you have a decision. And pictures of nice rifles are always welcome.

Yeah, I've got some thoughts. I'd strongly encourage you to go look through a Vortex Viper PST 1-4x TMCQ MOA (capped turrets). The URL to it on the Vortex site is here: http://www.vortexoptics.com/product/vortex-viper-pst-1-4x24-riflescope-with-tmcq-moa-reticle-capped-turrets. It's slightly north of 14 ounces with a wicked fast reticle; at least for the way my eyes work. I used that on a 16" barrel upper from Carbon Arms (a forum vendor) and blazed through a couple of shoot houses in a match at a training facility near Ft Bragg, NC. It was the first time I had been in a match like that, inside a structure blasting in just about every direction. It was wonderful fun.....anyway. Longest targets at that match were 200 yards or a tad more [the other stages :-) ]. Sounds like the typical use range you are expecting with the exception of an unspecified "major."
Put it in either an Aero Precision Ultralight mount (maybe the SPR one for a more forward position? Select one here: http://aeroprecisionusa.com/aspx/store/listing.aspx?catid=3)that clocks in at 3.36 ounces.That gets you on the rifle for a total weight of 17.8oz. But, don't forget the Vortex switchview lever for the complete package.
Or you could grab the slightly heavier Warne XSKEL mount, if you prefer.
In the end that saves you many hundreds of dollars that you could apply to the ammo, match fee, travel, food, and lodging to that unspecified major-match-someday.
If 1-6x is a deal-breaking need, then you shouldn't even mention the Nightforce and just drive on. I agree that the Leupold model you mention looks good and is an admirable weight. FOV specs look very good also. Then I look at the price and die a little inside. I am advocating for this particular Vortex because your candidate NF scope is 1-4x.
I see the Leupold for about $1300 online where the Vortex I propose is $480. Assume the mounts and levers are a wash between them. That's big money. However, compared to some other 1-6x scopes that seems competitive.
In the end, after consideration, I'd encourage you to reconsider the need for 1-6x. If you really think that is a likely need (not wanted, but actually likely) then that Leupold looks good on paper. I've never had the opportunity to use that or another Leupold like it. So then grab it and go.
But, if after re-evaluation, you don't actually need that 6x at the top end, think about the Vortex I've mentioned. I've used it on multiple matches and it's a workhorse for me in that range. I shoot Open/Unlimited as a general rule, but that one is my 'go to' for a great 1-4x that matches how my eyes like circles with dots inside. For 1x speed on target I think it's truly excellent. Plus, you'll probably save money for multiple matches and a bunch of ammo.
Good luck regardless and I hope you enjoy whatever scope you select.
Best Regards,
Mike

I suspect people will want to know what weight Bolt Carrier Group you are running, also.

Might find a long 308 hand guard from SLR Rifleworks.Damn. no forearm. After receiving the barrel and doing some preliminary fitting I called the supplier of the AP Custom ferearm and they don't have it, although that isn't what the web site had said. So I have been searching for another carbon fiber forearm, so far to no avail. Any suggestion on a good substitute. I don't want a lot of rails, I think it needs to be at least 15" and 17' would probably be better (24" barrel). At this point I will consider aluminium, it looks like the rifle is going to be over 10lbs, so a few extra ounces isn't a deal breaker.
mic2377; thanks for the tip on the Fulton Armory barrel, it is a beauty, now if I get the forearm I could even shoot it.
CarbonArms.us is possibly an even better option.
And I'd look over at JP or Lancer.

I think you are saying that you dialed your scope for 500 and it was right on, then from 500-600 you were 36" low. 36" low is 6 MOA. I suspect that this is a combination of you not shooting the bullet that the scope is calibrated for and or a delta in velocity. I also suspect that you were shooting at steel and not an NRA type of target. The only way to know you were really 36" low would have been to keep holding center and come up 6 MOA. If you were holding on the 700 but hitting 600, its hard to know exactly how high/low etc you are. To keep things in perspective the bullet drops about as much from 300-500 as it does from 500-600. This is all to say, unless you know, you might have been hitting not quite 36" low, combine this with a bullet that drops faster than what the BDC is made for an a 100-200 FPS less load.
In general the BDCs are usually pretty close but they are not exact unless you are shooting the exact load the BDC is made for. There are also environmental factors that play into things. A headwind can make a 1MOA difference.
Of the 68-69g bullets out there the 68 has a far worse BC then a 69 SMK does. The Lapua is even better and now with the 69TMK, that bullet takes the cake when it comes to BC.
Also, unless you shot 300 and then to 600 on the same day at the same range your scope could have moved a little.
I had missed the memo on the new Tipped MatchKing. Wicked!!

Join us in USPSA Heavy Metal. The Optics division uses a .308 rifle, 12-ga, and .40+ Limited-10 pistol.
What are the limitations on the shotgun type? Pump only?

My Open gun has an EOtech 512.
My Versamax had an XS sight rear V added along the vent rib. A Fiber Optic "bead" up front.

A little update, but I have not made final decisions. What I am looking at now: a Fulton Armory 6.5 Creedmore 24" barrel, AP Custom Carbon Fiber Forearm, Vortex Viper 6-24 Scope. Comments?
All three components sound solid to me.
I own a different Criterion barrel (.223 18" hybrid profile), have owned the early Carbon Arms hand guard in .223 size, and I have two Vortex scopes (1-4x Viper capped and 2.5-10x PST). I think highly of all of them.
What are you thinking about for an upper receiver? I'm gathering from other threads that the barrel-to-upper fit can be critical for accuracy.
I don't have any recommendations, unfortunately. But, the 6.5 Creedmoor should rock nicely.
-
You'd be surprised at how some aluminum or aluminum-magnesium allow hand guards can be as light or even lighter.

This may be a bit of a drive, but Cawthon Cartridge Club out in Navasota has plenty of bays and open fields to shoot your shotgun if you're looking for a long term private range. Memberships are a bit pricey, but the facilities they have are damn useful. They have USPSA and 3-gun monthly matches which definitely take advantage of the area available at the range. Don't worry about your shotgun being frowned on, the only guys we look at strange because of their shotguns are Open Division shooters (but that's because we are all jealous of the box mag "unloaded shotgun starts"
)Don't hate our Open shotguns because they are beautiful.

I use an EOtech 512 on my MKA-1919XN shotgun which is an AR-ish shotgun. I love dots inside circles for a fast reticle. I happen to be faster that way. Plenty of people like the EOtech way. Many others prefer the Aimpoint style of one dot. My personal preference for short range work is EOtech. If I make a more defense oriented AR and I go 1x, I'll use EOtech, no doubt.
-
Yes, I'm rethikning this idea. I would get more return from improving my skills and getting my Open kit running in top form.
We will see. You and I might still want to have a "6mm" project for ourselves. :-)
I very much appreciate all the input in this thread. I look forward to reading any others that come along.

I was thinking of a 243 LBC barrel from Black Hole.
Arnie, have we handled any questions remaining? I don't want to highjack your thread.
If I had the budget, I'd definitely spring for a SCR-11 side charging receiver set from JP. I think they look awesome when I've seen the videos about them (and the LRP-07 big brother to them).
But, they cost serious money. They look like they operate very smoothly.....just really pricey.

At Ironman the ranges for the bonus targets are generally 500, 700 and 900 yards. You can shoot all the ammo at them that you want, until you time out. And I agree with Stlhead, just go shoot the match, borrow a long distance gun the first year and get a feel for the match before you build a gun specifically for that match.
Doug
Thank you. I do appreciate the advice.
About how many long range targets are there at Ironman?
Soonest that I could possibly go would be next year, regardless.

Isn't that gun well north of $2000 *and* needs an SBR tax stamp? I've had the pleasure of firing a true MP5 and UMP 40 from H&K, but ouch! I'm not sure I can swing that. However it seemed like a great gun in your videos. More things to consider.....
I have enjoyed your blog posts. Looks like the PCC is a critical element for many Trooper competitors, based on your reported use pattern.
Dr. J, this borders on a thread-jack, but I can say that the JP isn't quite as expensive as you estimate. At least the one I made in their Rifle Builder isn't that expensive. I did not opt for the SCR-11 side charging upper. That would drive up the cost by hundreds. My build clocks in about about $1500 on their site (uses the JP-15 style upper).
