DDM4 V11 S2W vs. DDM4 M12

[Little Creek]

Do these weapons share the same gas block and chamber dimensions? I know the M12 is a military style designation and the chamber is supposed to be the ultimate for an accurate 5.56 weapon. Do they share the same barrel profile? I just brought a DDM4 V11 S2W home and noted, from the web site, that the weight is almost identical to the weight of the M12, yet the former has a longer rail by 3". Thank you DD for putting the QR for sling swivels on both sides of your version of the KMR.

All of our barrel have 5.56 NATO Chambers. The Mk12, in true form, comes with a MK12 gas block that attaches to the barrel with two vertical set screw which index into dimples on the bottom of the barrel. The v11 S2W has our OEM pinned LPG that attaches to the barrel with a single taper pin. The barrel profiles are different but close in weight. Notable differences are that the v11 S2W uses 4150 CMV Steel and the MK12 uses our special blend of Stainless Steel.

Can't get any closer to "right from the horses mouth" than that.
