GEISSELE MRGG 6.5 CREED WRITE UP AND REVIEW
- Thread starter JohnDeereGuy1996
- Start date
I run the bipod in the middle and i'm seeing roughly .2 mils of drop going to a tripod. It's very consistent and repeatable as well, so I am not too concerned about it tbh. There's a lot of variables that go into positional poi shifts so take everything with a grain of salt until you have a control group and can actually isolate the source of the problem. If it does become too big of an issue maybe geissele will have to redesign the handguard and barrel nut but I doubt that'll be anytime soon.
This is logical, in most cases it's not easy to work with the bipod located way at end of the rail from an ergonomics standpoint.
Took the LaRue MRGG out today with its new Paul Ross 22" Bartlein 6.5 Creedmoor Barrel.
Two 5rd groups, 1 suppressed and 1 Unsuppressed using my standard handload of 140 ELD / LAPUA SRP BRASS / 40.4gr H4350 AND CCI BR4 PRIMERS.
Not too shabby....

Here is my experience:
1. The bolt release on the right side is very stiff when you but gets easier to manipulate with use.
2. There is zero wobble between the upper and lower receivers, but I do have to use a plastic tool to push out the takedown pin.
3. As always, the trigger is amazing.
4. My rifle came with a hard case and beanie.
5. I purchased from Rooftop Defense during their Labor Day sale and I saved a lot of money - like, a lot of money.
6. All groups were fired at 100 yards unsupressed on a bench using bags with a Vortex Strike Eagle 5-25 scope. After see how well this rifle shoots I ordered a Nightforce ATACR 7-35 today.
7. The recoil is pleasantly smooth.
8. So far, the favorite load for this 1:7.5 barrel is the Black Hills M1200C. After talking to one of theirs super technical people, the M1200C is a Hornady projectile with the exact same external characteristics of the 140 grain Berger hybrid projectile the SOCOM contract calls for. In fact, I was told their employees can't tell them apart with eyesight alone and that they shoot almost identical. You will see below I had outstanding results.
9. Interesting result was both types of Federal Gold Medal would have been extremely tight if it weren't for one round from each group doing its own thing.
The next time I take this rifle to the range will be for 10 round groups using the top 5 or so performing ammunition.
So, expensive rifle? Yes, but I payed not much more than a Larue MRGG and this rifle has a longer handguard with a built in ARCA rail. Sweet!

That's impressive, especially the Black Hills load, even more so considering they're using the Hornady Aeromatch bullet.
Thanks for taking the time to post this! Unrelated side note, but when I get on Reddit to try to find information about a particular rifle, all it is is glamor shots. I like knowing how the thing performs, great review.
You are welcome. One thing that I didn't mention is all groups shown were after I fired 200 rounds to break in the barrel. My first group fired was using the Black Hills so that's why that group is centered.
The first group ever fired through the gun (rounds 4 through 8) was this group.
Out of curiosity from someone just getting into 6.5CM why BR4's instead of 450's? I kinda made the decision to go SRP brass as it's always easier to find SRP's vs LRP's.
I’d assume because BR4 cups are as thick as 450, but the primers are allegedly more consistent.
Makes sense, I actually have both, BR4's have been sitting around for a while unused. Guess I'll try both.
Agree. Why would there be that big of POI shift if the barrel is “free floated”? Like you pointed out, it must be tension on the barrel nut. This puts the Seekins and LMT 20-22” guns at a distinct theoretical advantage.
On another note, it makes absolutely zero sense to me for SOCOM to pick a 14.5” 6.5 Creedmoor rifle with a stainless steel barrel, meant for use by an “assaulter”. They must not care about barrel life then.

I'm simply asking for my knowledge, but aside of the MRGG-A "reference rifle rhat LMT is releasing early next year, is it confirmed that the USSOCOM contract is for stainless steel barrels over chrome lined?
Yeah, the guy I spoke with ar Black Hills was careful, and told me up front he would be, about the details he gave me about the military contract ammunition versus the civilian variant. Maybe the ammunition is desired by USSOCOM to not be outside of military use, and I imagine the technical expert (probably an engineer) signed a non-disclosure agreement. However, the civilian variant is pricey at MSRP, but can likely be had for less than MSRP. It shoots great in my rifle, so I'm currently okay with the M1200C...currently.
Did a little more digging and found black hills actually replied to a comment on this video and confirmed it's an aero match projectile.... Not that there is anything wrong with the aero match per se, just had I known this prior to purchasing M1200C I would've gone with factory Berger ammo which is cheaper, runs a Berger bullet and is loaded in Lapua brass.
I agree with you. Black Hills is not alone, they and IMI also use the Hornady Aeromatch bullet instead of genuine Sierra matchking bullets in their 77 grain 223 ammo.
I've never tested the Hornady Aeromatch bullets against whatever they are copying, and maybe it's just psychological, but I feel better having the real thing. Especially for the premium price.
The Black Hills 77 grain OTM is a Hornady bullet, but the MK262 Mod 1-C is a Sierra bullet like the military contract even though it is available to the civilian market. I use that ammunition and the AAC 77 OTM (non-Sierra) exclusively and both have similar results.
Free floating in a misnomer. Compared to non FF barrel there will be less shift but almost all modern FF rails attach via the barrel nut. When loading into the rail, you will get barrel deflection causing a POI shift. Some are better than others but its there.
I am a HUGE G fan and run a ton of their product but the Seekins system is clearly ahead when it comes to design as a precision platform. The greatest barrel in the world means nothing when the POI shift when loaded makes your cone of fire double or triple.
For the money, seekins is about half the price and a MUCH better value. If it was my money I think you are better off throwing a Bartlien or other custom cut rifle on a seekins and still come out money ahead. The new JP with semi monolithic would be closer to the G in pricing.
You are 100% correct about the solicitation. Its all kinds of fucked up. If I had to guess, they split it up this way to keep the award threshold under a dollar amount (whereas both combined would trigger a different level of procurement) to make it easier/cheaper/faster to do a weapons award. What makes zero fucking sense is to have a cut rifle barrel on the 14" "assaulter" and a Chrome Lined on the 20". And obviously it would make much more sense to award the same rifle in different barrel legnths
If I was a betting man for the types of unit using these, the 14.5" is going to be used overwhelmingly if given a choice. If range becomes an issue, a bigger platform (like the MK22) would probably be employed. It seems very redundant but who knows what the technical folks and contracting were thinking when they baked up this idea.
You'd thing the Geissele would excel in the 14.5 role due to its Chrome lined barrel, the fact it recoils about as much as my ar15s, and poi shift should be diminished due to its shorter rail. I do agree that the 14.5 gun will be used predominantly as the extra range from the 20 inch version won't offset the increase in size of the platform for their uses.
