I’m honored to even be mentioned here

That’s a nice Mod H.  I’m not much in the clone game anymore, but it does beckon to me from time to time.

Put together a few more pics of the completed Mk12 Mod 1 build. I think this is as close as I think I can get it short of a transferable H&R M16A1 lower -- I’d like to do that somewhere down the line. I was fortunate enough to secure an Intl Mil Co H&R M16A1 lower in batch 1 about 5 years ago. I had originally planned on building it into an M16A1 clone but stumbled upon this thread and started on a Mod 1 instead.

IMI 77gr SMK is my go to. Always had good consistent groups with it.

This one won’t get painted since it wouldn’t match my reference pics. But I am working on painting the SPR lower to match the issued upper, so it will be in good company.

Thanks to Chris at Intl Mil Co, wakebrdr142, Engineer5, PerfectTurn, ringer706, and all the other folks here who helped me put this together over the last few years.

Still shoots pretty good with the takeoff barrel.

Intl Mil hydration lower, geissele ssa-e, older unmarked colt cs stock, built the same as newer stocks but shorter, a few things that probably should be changed if I ever found them.

That's gorgeous. Hoping to build something similar with my 2002 rev B barrel, with original early parts. Gonna be a very long, very expensive journey though

I did exactly that and I liked the setup. I have ARMS mounts now, which are cooler, but the Larue setup was better, IMO.

I would say it's just right, but I had a 1.93 on mine without the Recce rail. It was pretty tall for me.

Recently picked up a PSA Mk 12 MOD 0 upper from PSA. This has the ARMS Sawn Sleeve on top that goes to the front of the hand guard.

My question is: Before I end up mounting any glass, do I need to loctite the sleeve (monolithic rail) or do I need to be concerned with it coming loose in the future?

Silly question, I know. My neuroticism is getting the best of me.

I already tried asking my wife's boyfriend but he wouldn't help me because it's date night for them.

Thanks.

Mine fit kinda funky, so I used blue Loctite to secure it.

Yours has a PRI sleeve, A.R.M.S. hasn't made theirs in like 15 years and they cost more than the entire PSA upper does. Regardless, as spec'd by A.R.M.S. the receiver clamp bolts/recoil lugs have a bit of thread locker on the threads to keep the nuts from unscrewing, but the screws for attaching it to the handguard don't. A bit of thread locker on those wouldn't hurt, there's no reason not to, but it's unlikely they'd come loose without it so it's not a hard requirement.

Anyone else reproducing these stickers?  There is a vendor (more than likely a member here) on eBay but they have ceased doing them now.  After all these years of having my build and an original deployment case, I wasn't paying attention and dropped the ball on getting a set.  Any help would be appreciated.  Thanks all.

It’s perfect for the mk12. Honestly one of my favorite scopes ive had in recent years. If they had just had some kind of circle to draw your eye in on 2x rather than having to rely on illum so much it would be perfect. Otherwise it nails pretty much everything I’d want for an optic for the mk12 or spr. Its lightweight has great glass, good eye relief, good turrets, forgiving parallax for its design, and a very useable reticle at 12x.

I lost my scope caps that night so I’m in need of new ones. Wish OHC would make some

Oh yeah lol. 88s are breaking tips which is more of a bullet issue. I single fed them and shot a decent group yesterday it was locking back with 4 O'clock ejection. 62s are short stroking with the A2 buffer. JP low mass buffer and polished spring are on the way. Real issue is the ELD M shoot, that's what i want to shoot, and I'm afraid to run them  cause of the tip issue which is a bummer.

Does anyone have an extra ARMS 38 SPR MOD rail they would be willing to lend me to digitize? A big ask I know, but doesn't hurt to ask. They are going for $2k if you can find one and PRI doesn't make their 38 repros in the correct finish. So, F it, I'll just do it myself. DM me you might be open to such an endeavor. Thanks.

As much as I liked the Rhodesian baby poo camo, went ahead and repainted with something a bit more practical for my area after switching out the stock and grip for a B5 LS2 and CAR stock with pad. Loving the Mod 0 just a bit more now.

Is that a bullet issue, or a mag height issue? I’ve used 123gr ELD-Ms in my Larue 6.5G upper and rando lower with decade old CPD 7.62x39 mags without any problems. Is the mag a hair too low in the magwell, leading to the bullet tip impacting the top of the chamber and breaking off the tip?

From what I've seen it's a bullet problem. 62s have no issues. It's just 88s.
