I really am looking to take the plunge by painting my entire mod 0. Currently everythingon the gun is painted in khaki/flat tan except the barrel, brake, top rail, rings and scope. I'm having trouble convincing myself to paint those oh so costly items. Thoughts? Recommendationd? How do I convince myself to do it? I'd like the gun to look like an atacs pattern over everything.




Edit, done!

Paint it, Those pieces can easily be cleaned up with a paint stripper without harming anything.

Yea? Any recommendations on how to do an atacs like color or something like the one on the lastpage w the mod
O that was comparing top rail sections? Best way to cover the lenses when painting?

Augee will have to explain how he painted his rifle but it looks like just a simple base coat of Krylon khaki with splotches of brown that he dusted with more khaki to lighten it up.

I always mask off my lenses with painters tape and then put the scope caps over that for an "extra protective" barrier, but its not really needed if you mask it off properly.

I just closed the caps on mine and all is good.

Looked like this while I was spraying it down. I put the base coat on out side. The rest is the sponge thing.


Don't forget to tape off the turrets and stuff.

Ok guys, I bit the bullet. Lmk what you think; I'm pleasantly surprised overall

Looks good

Why must all of you guys taunt me with these good looking painted Mod 0s?

I got to fuck around with a real deal mk12.

 

....

Just got it put together.
High caliber sales upper, and lower
Geiselle ssae trigger
Hard to find leupold  TS30 scope

Anybody have the specific barrel dimensions/drawing and what reamer is used for the chamber?

Looks great!  I've been searching for that scope for a long time......

Great job, cschelk2.

RadOP nailed my "technique" pretty well.  

All I did was spray a base coat of tan, then go back over it with brown in diagonal "stripes."  Then, while it was still wet, I broke it up a little with the tan again, and "dusted" it at varying heights, and "pass" speeds, to get different feelings of "depth."  I went back and forth a couple of times with a little bit of brown and tan until I got the desired effect.  Once I was satisfied with one side, I just flipped it over, and re-did the other side.  

Beyond that, my only other suggestion is to use light coats and multiple passes, particularly when using masking tape, to prevent seepage and raised "ridges" where the paint builds up.  



You can do both.  

The only modification to most MK 12 lowers over the M16A1 is the installation of a two-stage trigger assembly.  I don't think too many of the Retro nuts would complain that you used a KAC 2-stage or Geissele SSA in your M16A1 build.  Bonus points for using the Geissele because you'll have "dimpled" FCG pins!  

I haven't even finished my MOD 0 yet, and I've already started thinking that it might be pretty cool to have a MOD 1 upper to go along with it...

Won't be affording that for quite a while, though.  

In the meantime, the MOD 0 went out yesterday, nothing too spectacular, just popping 6" clays at 100 yds with the ACOG, but lots of fun.  

~Augee

Minus points for having dimpled hammer/trigger pins on the a1 ; they were only used on the 601.

I agree with the idea of building both... you're halfway there with the lower so why not? I almost posted a pic of my Mk12, 603, and 604 together in response of his post. Only thing that stopped me is my potato camera can't take a passable photo after dark.

Augh! Double post. Cursed phone.

"In country repair job."  



~Augee

Niiiiiice.  I like the way you think.

ETA - Back to a Type E stock.

Beautiful, but she's begging for an A1 grip and mk4.



BTW, where'd you find the stock? All the E's I've found are beat to shit.





 

Be advised: Nice pair of ARMS #22Hs for sale in the EE.  Listing is NOT mine.

Not anymore...





Mod1 here I come.



 

I wanted to say thanks to Augee for giving me the idea to put this post together.

I have always had an interest in the early SPR/MK12 Mod0 and been fortunate enough to accumulate some of the more difficult to find parts.  I thought it might be useful to show a side by side comparison of the various generations of Precision Reflex Inc. products used on the rifle and give a brief description of the product.

TO BEGIN

The first picture shows everything together. The top three pictured are the earlier versions of the MK12 Mod0 using the original PRI forearms and wheeled front sight bases,  while the bottom one pictured is the "Mod Holland" version using a Gen III PRI forearm.

PRI Gen1, PRI Gen2 Variation, PRI Gen2 and PRI Gen3

Three generations of PRI Carbon Fiber Free Floating Forend are next pictured below, each with their corresponding flip up front sight.  The Gen1 and Gen2 are a similar in appearance, each using a standard size threaded barrel nut, a locking collar and a "straight" profile free floating carbon fiber tube.   The Gen3 is noticeable different than the first two generations, due to a larger barrel nut and retaining  collar.  The differences between individual generations will be shown later in the post.

PRI Gen1 (top), PRI Gen2 (middle), PRI Gen3 (bottom)

GENERATION I and GENERATION II

The Gen1 and Gen2 forearm use the same style threaded barrel nut and locking collar. One major difference between the two generations is the diameter of the carbon fiber tube, the Gen1 tube roughly measures 2-3/16" while the Gen2 tube measure in at 2".  The sides of the Gen1 forearm lack any additional holes to accommodate longer rails while the Gen2 forearm has them.  A quick identifying feature of the Gen1 forearm is the additional set of holes at the 5 and 7 o-clock position at the rear of the forearm, and the lack of a heatsheild.

Pictured below are good examples to show the differences in not only the Gen1 and Gen2 but also two versions of the A.R.M.S. #38.  Although both rails are marked "A.R.M.S. #38 SPR MOD Swan Sleeve Cal 5.56",  it can be seen that the location of the logo is slightly different. The most notable difference between the two swan sleeves is the top rail spacing.

GENERATION I

The Gen1 forearm disassembled into its major components.

The top view of the disassembled forearm shows the two piece top attachment rail for the A.R.M.S. #38 SPR MOD swan sleeve. If you look through the bottom set of holes on the forearm, the lack of a heatsheild can be seen.

While looking through the archives, I found a post from a member back in 2004.  He had a Gen1 that came from the first run of the forearm, the carbon fiber tube was oversize by .030".  This required the modification of the A.R.M.S.  #38 rail to fit the larger radius of the tube.  I thought that was kind of interesting, I had never heard that before.

PRI Gen1 slightly oversize with A.R.M.S. rail cut to fit the larger radius (for comparison, normal rail top and fit rail bottom)

Attached File


GENERATION II

The Gen2 forearm shown shares the same threaded barrel nut and locking collar as Gen1, the heatsheild and the addition of the rail mounting holes running along the side can clearly be seen too.  A feature that the Gen2 shares with the Gen3 is a 8.5" top attachment rail used to attach the A.R.M.S. #38 rail to the carbon fiber tube.

GENERATION II Variation

A variation of the early rail that has features found on  both the Gen1 and the Gen2, possibly an "old new stock" Gen1 tube that was modified with Gen2 features prior to leaving the factory.
The upper now belongs to member secretwheelman.

GERERATION I and GENERATION III

Since the Gen1 and the Gen2 are similar, I thought I would show a couple photos comparing the Gen1 and Gen3 forearm. The side view and the top view both show the difference in profile and the redesign of barrel nut and retaining collar of the Gen3.  Although it is probably hard to tell from the photo, the diameter of the Gen1 carbon fiber tube is about 3/16" larger than that of the Gen3.

PRI Gen1 and PRI Gen3 (side)

Attached File


The top view shows the difference in the way the A.R.M.S. #38 rail attaches to the carbon fiber tube.  The Gen1 has two small rails each with a threaded hold while the Gen3 uses an 8.5"  rail with threaded steel bushings.

Finally, the two generations of forearms disassembled to show their major components.

A.R.M.S. #38 SPR MOD SWAN SLEEVE

Atlantic Research Marketing Systems made three versions of the A.R.M.S. #38 SPR MOD rail for the Gen1/2 forearm.  Two of the three versions are pictured below, not shown is the peq2 version.  The end of the missing peq2 version has a similar shape to the end of the A.R.M.S.  #38 peq2-3.

Two generational versions of the swan sleeve are shown below, the A.R.M.S. #38 peq2-3 rail for the PRI Gen3 and the ARMS #38 SPR MOD rail for the PRI Gen1/2.  The redesign of the Gen3's larger barrel nut and retaining collar are responsible for the stepped notch being necessary for use of the rail with the Gen3 forearm.

FLIP UP FRONT SIGHT BASE

The PRI flip up front sight bases pictured below were used with the SPR and the MK12 Mod0 .  The Gen1 sight with an elevation wheeled front sight was found on the SPR while the current version of the sight was used on the MK12 Mod0 .  They are similar in design, both use four set screw to attach the sight to the barrel but are slightly dimensionally different.

Thanks for looking and hope this helps

Pics added back in on 5/21 and to add, for a time I owned one of the PRI buy back uppers.  It now belongs to member here.  High quality pics have been post by LC detailing the parts.  I thought I would add one of the bcg and ch.

Surprisingly that one is out of an Izzy kit. The shell was nearly perfect but the butt plate was trashed.  I had an a1 grip on it with the a1 lower , but figured with the a2 I could get away with something a little more pleasant for my big mitts. When I get my hands on a black a1 lower it'll be back to an a1 grip.

Still debating the glass. I want it to be perfect, but I may also consider deviating with a viper 2.5-10x32 ffp. Probably will come down to what pops up when I have the money in hand. I'm somewhat impulsive.

Nice collection of parts.

Damn you with your temptations.  I don't need another build, I don't need another build, I don't nee...................well maybe one more wouldn't hurt.

Will probably kick myself for not buying this but I'm happy with my Turner sling on my Mk12 so here, one of y'all need this:

ARKAR

If it makes you feel better, it's no TAS-1UMSS

I'm interested to see this.

Cross-post from the Spec Ops thread in GD.  A little Mod1-in-the-wild for your Wednesday morning commute.

Fuck yeah. It's nice to see some SOPMODs on Mod 1s in the wild. I suspect it's still an A1 lower(?).

Right. M16A1 lower

Does anyone know where to get a KAC rail for the Mod 1? Is there another brand that mimics this that would be acceptable for a Mod 1 build? Thanks.

Look further up the page for your answer,

here is a hint,

http://www.ar15.com/forums/t_7_22/1241842_Knights_Armament_Free_Floating_Quad_Rail_Adapter_System.html

I need one as well.  though I am leery dealing with new users having low post counts

Thanks!  It was late at night, I wasn't looking that hard! Cheers!

That is my issue also, I really wanna pull the trigger on one of these. But no Pic and low post count and no EE ratings.

I got a picture from him of one of the 6 rails. Came with all panels, rail looked new, I don't know if the box is included.

I got a picture too but I don't see any KAC logo or writing on it...

I don't want to be "that guy" that referenced an ad that led to a bunch of people getting ripped off and I know y'all don't want to get ripped off.

I picked up a KAC rail a few years back and markings were inside the rails.

Sent you an IM

I know, it needs paint.  I did a little 500-600 yard shooting today.

:-(



Edit:  How it came out of the box.

 

 






 

HaHa!  No, I was actually shooting another guys MK262 ammo at his insistence.  He's in the 'business' so it was not sweat off his back.

thats just not right!
