Little shooting today. Mil'd the milk jug at 300 ish. Placed a few small water bottles around the same distance. 50 gr Vmax is NO joke outta this barrel.






























































10 rounds: 4 dead containers
























Edit: I meant To add- I've been shooting off the versa pod lately, and I think I prefer it to the Harris. Not a fan of the sensitive release mechanisms, but other than than, as long as I have time to load it, I feel more consistent with the versa.

Its got knurling on it and is marked California. I figured I'd have got one of the Nevada made ones.

Unfortunately my barrel only allowed for 2.5 turns on the threads so now the whole rifle is apart waiting on Ron Allen to help me out with a different collar.

Ron will get you taken care of, I just went through this with my Shilen barrel that was profiled to crane spec not newer Allen spec.  We discussed the issue quite a bit, it just comes down to crane being 2-3 turns and Allen requiring 5-8 for best performance and lifespan out of the can.

I love you guys

on another note, my criterion barrel should be here next week.  Had a funny LOL when the wrong barrel showed up a couple of weeks ago.  stainless HBAR service barrel.  (oops)
My LGS guy is awesome and he apologized.  Even managed to sell the barrel on a new build to another customer.

I wonder if that's the spec my barrel was made to. In any case Ron already hooked me up with a custom collar. Super fast response time. Can't say enough about how quickly and easily he solved the problem. It just has to get finished in black oxide then I'll finally be able to shoot my can.

If your steps at 1 5/8th  instead of 2.4"  that would be the old out dated Crane spec.  2 turns is functional it's just not best for the can.

When Crane was building Mk12 (0 and 1), the only collars OPS INC made were the long ones for their 12th Models.




After Phil passed away, Ron Allen (Phil's engineer) took over the business under Allen Engineering. Some minor changes have been made in the suppressors (such as finish and some of the lengths on certain models), and also made the collars a little shorter. Functionally, there is no difference between the short and long collars. The important area has remained the same, however, just a little less material on the rear.





 





What I believe ADCO is advertising is that they have 2 different lengths of collars.







The 1st model (mod 1)being the standard one from AE


and the 2nd model (mod 0) I'm guessing ADCO make in-house that is long...similar to the original collar from OPS INC.

The bottom line is, all issue rifles used the long collars.  The short collars are a later version, and while they work perfectly well they are not "clonespec".  In addition, some barrel profiles and a Mod0 FSB may result in the long collar hitting the FSB before the shoulder.

Liking it a lot.  I've had both the Mk4 3.5-10x40 and 2.5-8x36 on my Mk12s , and I like this scope more for my purpose.  My Mod 0 is a 6.8 deer rifle with an SPR shell. VX-R Patrol matches that.  Reticle is thick so I probably wouldn't put one on a dedicated paper puncher.

The upper and lower vent holes.  3/8th inch at 45 degrees.  When I modeled the CAD file I originally did so based on the Gen II repro which is the same as the Gen III.  However,  the Gen I has larger holes on a different plane that puts them closer to the rail holes.

I feel like this is or Radop's post is OP worthy. There's a lot of info on there but I feel like either one of these in bold might clear it up. If you're going as spec as possible long collar is the right choice. Now choosing where to get you're barrel from is another story since manufacturer's specs seem to be inconsistent on placement of the shoulder for the collar.

This is very easy to clear up.  Crane spec was to place the step for the collar 1-5/8th inches back.  Per Ron allen they told Crane to change that (the step placement) because 2 threads of attachment were not enough but they (NSWC) did not comply because of reasons I cant put words to.  Now per AE's updated spec sheet (not all that new) the step is placed 2.4 inches back measuring from the tip (crown) of barrel and back, this allows for the minimum of 5 rotations to be achieved; max rotations is 8.  BCM and Ballistic Advantage both profile to this spec, other manufacturers (douglas, white oak, shilen, etc etc) have been covered on this topic to include the potential OAL lengths of barrels sometimes being greater or less than 18"  which would only affect Mod 0's and the placement of the Long collar possibly bottoming out on the GB before hitting the step.  If you look back you can find plenty of old SPR/MK12 Mod0's with the long collar that touches the GB and some that are just barely forward of it.

Not sure what you're talking about as far a vent holes. Are you talking about the rail holes on the side? Or that I'm missing a rear lower vent?




The upper and lower vent holes.  3/8th inch at 45 degrees.  When I modeled the CAD file I originally did so based on the Gen II repro which is the same as the Gen III.  However,  the Gen I has larger holes on a different plane that puts them closer to the rail holes.
No shit?? That's purdy neat man. What size were the gen 1's?? SWM, what size is your hole???!!!

That sir....would be stealing. We actually just donated the remaining 600 rounds to homeless blind developmently disabled children. They need match ammo too.

How much are you guys expecting to pay for a 4 position colt buffer tub with h buffer, springs, castle nut, and end plate? I feel like I have a good grasp on prices for everything else but seeing just the buffer tube alone for $50 on here is throwing me for a loop. Would $70 for all of it be an average deal? Low? High?

Don't worry about buying a Colt buffer tube set up.  Just get what ever flavor as long as it's mil-spec.

Alright! I finally was able to repaint my upper with the new (MK12 approved) rail, haha! Just letting it set and dry.  The other incorrect details will have to wait.

Found a mr/t local that I'm trying to raise funds for, going to be throwing some parts in the ee. I have two sets of no stop mediums, if anyone in here wants them pm me.



Blue, great job on removing the stops, I was interested in seeing if you were going to mill the smaller "stop" when you removed the material (not sure if that makes sense) and it looks like you nailed it.
