Re: DM4
Well I was that client that was told that to my face, so never say never i guess,
Flatten primers of all ammo commercial 223 and 5.56, and blown primers with some also it sometimes takes a piece of primer with the firing pin into the BCG im also getting about 100 FPS more on average than guys with the same ammo but with 16inch barrels and mine is a 14.5.
I was told the reason for this (1 of the 3 times the rifle and me have been to you guys) that the bullets where too big, that was the reason for the Over pressure, a caliper at a different shop with the same ammo actually revealed that to be a lie.
Also the bullet gets shoved into the lands of the rifling and hard. I have had to MORTOR my gun to clear it. After 2 different gunsmiths that problem now has somewhat gotten better,
Also the gas block was leaking so i had it replaced with a ergo one so its not that anymore, funny though that i was still getting overpressure issues with a leaking gas block.
So in total
Chamber has been polished twice
New Gas Block
New extractor spring and O-Ring
New Bolt ( Lugs where peening on the original)
Bore has been lapped
Chamber Lead has been cut
Heavy rifle length buffer and buffer tube
So if its not all those things....

Re: DM4
There’s your problem, ‘mortoring to clear it’, that chamber is on the extremely tight side, get them to recut and headspace the chamber.

Re: DM4
I was under the impression that the DM4 used a Truvelo barrel?

Re: DM4
Does this mean the Billet guns are going to go to dealers? Are there going to be rifles available any time soon for the someone walking into one of your stores, or should one move on to another supplier/manufacturer?
ive been asking since November and based on what they are saying, theres not going to be anything available from DSG for the foreseeable future....

Re: DM4
I just love the comment about bulk ammo... Strange that it runs fine in some rifles... cough cough
