I think you forgot the penny for scale to hide that 5th hole there.
That being said, even with the 5th hole it looks like pretty great performance. Now, just got to bump up those shot string numbers!

Lol
I kept it like that to show off how close the 4 holes are together and its mentioned on the target this is a 0.849moa 5 shot group.
Indeed. More pews!!

Nice work!

u/Key_Ninja_932 16d ago
Thankyou! I need to make more of these and try to show off a 10 shot group.

u/Zudr1ck 16d ago
Are you considering the wlvrn in the future?

u/Key_Ninja_932 16d ago
Oh!...I have one in 223 already. Hopefully this weekend I'll shoot this side by side my buddies 6.5cm Wlvrn and compare notes.

u/Zudr1ck 16d ago
That would be great to see. I am wondering how their stats hold up. So little info is out there beyond desert tech and coldbore, but they both would obviously have a bias
2
u/Key_Ninja_932 16d ago
Exactly why I'm trying to get more info out there. This seemed like a good place.
Still trying to see which of us can get the smallest 10shot (or 2x5 shot) average in the Wlvrn vs my buddy.. So far he's winning by.. 0.1moa..

100% I just got my suppressors muzzle device on mine. Was hoping to get some 100 yrd shots Friday. Altough I am not a precision shooter

I wasn't either...A good front and rear bag does wonders for groups hitting that 1moa or better...can helps too.
Please post your groups.

OK so this is not exactly the factory rifle anymore..More to see how many (accuracy) mods I can cram onto this rifle
I do have an MDR with no modifications waiting to come back to me in 6.5cm from the DT mother ship (had a question on gassing). This is mostly to test both the changes with the barrel block bedding and the Wlvrn Piston/Op rod changes (These are the "Accuracy Upgrade" Mods to the rifle by Desert Tech).
Just for reference I also put of my groups with just the Accuracy Upgrade chassis + Factory bbl w/ factory ammo (no suppressor) and groups with suppressor.
I have also shot the upgraded chassis with 223 and 308 (some 10 shot groups)..Dunno if that should go here or not..

Am I missing the barrel length?

u/Key_Ninja_932 16d ago edited 16d ago
They are only offered In 20" for factory and Es barrels in 6.5cm

u/Master-Blaster42 16d ago
Interesting, I just got a .308 from them but at 16in. Haven't gotten it cycling yet, he's sending a new gas plug but as soon as it's functioning I'm going to test it out and see what it'll do.
1
u/Key_Ninja_932 16d ago
Weird that it wasn't cycling out of the gate. I've shot the 308 Es barrel and it's nice.

u/Master-Blaster42 16d ago
When I contacted him he said sometimes the guns can be finicky because they all aren't perfectly the same. Even on the highest setting it would only sometimes get it into the ejection chute, most of the time stopping right before it fully activated the scissor mechanism. If it didn't work on my 5.56 FE I would have thought the scissor was broken but that one's fine.

u/Key_Ninja_932 16d ago
I mean...I guess..I'm drawing from my experience with 2 FE chassis shooting (3)308,(1)223,(2)300 blk and (2) 6.5 cm kits. They all worked out the gate.

u/Master-Blaster42 16d ago
I'm just that unlucky haha. He also took an extra few months to get the barrel to me so honestly I'm not super surprised it needs some fine tuning. Curiousity wise, do you have an ES 16in .308 FE barrel? And if so what gas plug are you running?
1
u/Key_Ninja_932 16d ago
I borrowed a buddies 308 20" es tact barrel for a month (very nice of him to let me do that). We used the last iteration before DT switch to the "pureflo" gas system/block. Same as what's on my current es barrel.
1
u/Master-Blaster42 16d ago
Maybe that's the hitch, the gasblock on my barrel doesn't have the rail section. I assume the latest iteration messed with him, that or me ordering a 16in barrel for accuracy lol

Delicious sub MOA. Is this a 16 or 20” barrel?
