Oct 8, 2008 · Re: MK12 MOD1 Beautiful job by High Caliber. Please let us know how it shoots. I run an OPS 12th and a USO SN-3 on my 18" Douglas. Results have been outstanding with both 77gr MK262 as well as Hornady 75gr 5.56 T2, certainly not unexpected from the Douglas barrel.

Mar 8, 2020 · The ADCO Mk12 MOD1 uppers are nowhere near the real Mk12 MOD1 uppers, BUT...they are excellent uppers and capable of good accuracy with good ammo and if the shooter does their part. Personally, if I were in the market for a Mk12 upper, I would...WITHOUT A DOUBT...spend the extra $250 and get an upper from High Caliber Sales.

Aug 12, 2008 · Re: Mk12 Mod0 vs, Mod1 To me, the mod 1 looks a lot closer to an M16A4 with a scope. The mod 0 has a much more distinctive look, which I prefer. It is also about a pound heavier than the mod 1, as mentioned above. However, weight in a precision type rifle is not nessesarily a bad thing, unless you plan to be hauling it all over kingdom-come.

Aug 13, 2022 · The 2.5-10x24 was correct for the mod1 (they have supposedly also received the 2.5-10x32 but not sure if they were issued from Crane or incorporated at the end user level). The mod 0 used the leupold 3-9x 36 MRT (ts30a2) and 2.5-10x40 vxiii/mk4 lrt

Jan 7, 2020 · Knight's Free-Float RAS replaces the standard hand guards on the AR15. This is the handguard that is used on the SPR/A, SPR/B, and Naval Special Warfare Command (NSWC) SPR aka Mk12 Mod1 or special purpose rifle. This is also the rail used on the USMC SAM-R. The Low-Profile Gas Block may be...

May 31, 2003 · Re: What scope for Mk12 Mod1 I have a VX-R patrol 3-9x40mm also, it's not on my mk12 mod 1 but would make a great SPR for 600m shooting where you don't plan on going 2 revs so zero stop isn't needed. The VX-R is a larger profile than i would like on my SPR, i just like the smaller objective scopes.

Dec 4, 2004 · Re: My take on the Mk12 Mod1 SPR Had a few moments (literally) to get out to the range today. I zeroed the NF 2.5-10x32 (great scope) at 100yd and set the zero stop at 5 clicks down.

Jan 11, 2008 · Re: MK12 Mod1 Those KAC lowers are sick. CTD has them for $650... Mk 12 upper from HCS shoots great with SW Ammo 77gr stuff. Rock river makes a nice lower, also, but it doesn't have the snazzy stuff the KAC one does ( as I'm sure you already know). But yah, I use an H2 buffer and spring in my mk12. No issues

Aug 21, 2020 · Im going with the HCS mk12 Mod1 upper and going to ask if he can get the AEM5 added onto the order. I did contact Allen engineering to order direct but never got a response. Still trying to figure out a lower as most are suggesting the nodak m16a1 lower but I …

May 5, 2009 · Re: Mk12 Mod 1 Parts list Needed. I bought an ADCO Mk12 Mod1 upper a while back and am satisfied with it. It is MOA or better with decent factory ammo. I am sure that it could do better if it had a better trigger puller behind it. It has been 100% reliable to date, only 200 or so through it though. I have also heard decent things about ...
