The Magic Trick™ about these is that once you know how many rail spaces one of the models of Block 2 rail are shorter/longer, you can literally just scale it to fit. Taken a couple hours to about the Mk18 rail to the same state as the M4s, which took over triple that (including ref double checking)

So I can finally say the main Block 2 is more or less good (Still have the Gas Block and a couple screws to finish it) So there's some obvious finishing touches - putting the screw grommets properly on, the Slipring and screws, and all the rail sections being given the slight chamfer.

Getting through it. Some bits inside and out to go (including the slip ring)

So, Unlike the Knights M4 RIS and M5 RAS, the Block II quad rails are entirely comprehensible engineering pieces, mostly because they weren't specced by committee. Gonna knock through 'em real quick. Also, because I don't think I showed it - TA31/M150 RCO/M4CP with Killflash ARD

Minus a Killflash/ARD (working on), I'm basically considering the TA31 (M150 RCO) good. Got the RMR mount version and I have the cap retention wire all GTG.

So here's a thing: The ECOS package for the ACOG comes as several variants to mount various microdots. I picked the Docter one because I like the way they look and also NIarms already has one, so suits me fine to not have the extra work. Then I start on the M150 RCO package: Not a Docter in sight.

Right - That's the ECOS done.

Aight that's the TA01 body done we're done we're moving, we're cooking moving on up et cetera et cetera. Mount to go, then probably one of the ECOS variants( there's 6- I'm not doing them all)

Gonna post it on regular account instead of NIA just because I'm so pumped to finally be back on it. It probably doesn't look much since the last post about it, but it's been a helluva clean-up as parts got merged onto the main body here. Stuff still to do obviously, but it's comprehensible.

It's taking a while, I know, but I think I've finally got this thing by the hairs of it's scrote. It's getting done.

So, I'm back on the ACOG(s). Threw out like 90% of what I had and started more or less from scratch, and through a slow, portion-by-portion I'm getting somewhere is better. Not "good", because ACOG's are a mess of idiosyncratic asymmetry that make it hard to do at best. Anyway, we're making progress

aand with the recesses cut on the rubber protective coating, the C79 is Done.

Very much one of those things where it wasn't looking right until it suddenly did real near the end. Still some deets to go (Scope body indents, and most of the rail mount infra, OTOH) but it's now looking legit.

Gotta say, #arma3 is a pretty damned pretty game

New year, new etc., Last vestiges of the DIY mentality in US SOF (ironically some of the last in line for the SOPMOD parts) - Fibreglass free-float tube. Initially these were sourced from Knight's Armament SR25s, but eventually they were using everyone's as available (Armalite, Bushmaster, etc)

Study

Just going to wish everyone a great 2026, stay safe on new years eve 🍾🎆🎇 2025 was yet another bumpy road for me and the family and 2026 is going to be probably even more bumpy than this past year, just got to wait and see where this roller coaster is going to end up this coming year 😖 #ThatsLife 🤷‍♂️

So after a frustratingly abortive shot at doing the ACOGs and not liking the outcome, I switched to something on the list that was more achievable- Insight VLI-002 (Or 001, Insight seemingly didn't make clear the distinction). The VLI was the first WML in the SOPMOD package, and was mostly a failure

aaand with the Wilcox mount that makes both of the formally adopted Aimpoint mounts in Block 1 SOPMOD - the M68 CCO with the Aimpoint QRP, and the ECOS-N with the Wilcox CompM mount.

Not in any way complete, but here's the first of the CompM2 mounts, the Aimpoint QRP (and lower-third cowitness spacer, which is a separate piece because the maximalist in me once again strikes).

The first M68 CCO - the CompM2 Aimpoint. 3rd of 5 for the Milspec ARs, first of Phase 3. To do: lens caps, mounts(several), the weird rubber sling that went over the adjustment dials, probably a rubber band

Okay, mad season over, and we're back. In a Patreon post I made yesterday getting everything up to speed, I mentioned not having done the Sawback charging handle latch for the Diemaco rifles - I have now corrected that.

Right, with the ambi mag release and the butt pad, we're only short the razor saw bolt latch for a complete C8A2, and if you can imagine the full A2 front for the moment (CBF rendering it) - the C7A2.

Finally, we're getting close to looking like what people think of as the C7 and C8 (the A1 and 2). Diemaco BUIS to go with the Diemaco rifles. Gotta do the rubber butt pad next.

Vibes so rancid today that I had to model something Canadian - TRIAD I Rail System

There's a few details to go (mostly the knob shrouds, lens protectors and their retainers and plugs, and pic mount)

Started on the Eye-Cancer Box, Mk.2 (the first widely issued one).

One of the things about the KAC Vertical Grip is that it's phenomenally hard to screw up- both IRL and to render in 3D. Today I needed an easy win, so that's what I'm doing. Almost done. Missing the battery holder and a couple detail tweaks.

That's the SOPMOD done. OTOH I still have to do the M203 Butt-pad because the CAF used them on the C7A2 and C8A1/2 onwards. Time to start working on more accessories

Obviously not done, but the SOPMOD stock is being worked on and it's well over the hump now.
