TLDR: John Thomas of Retro Arms Works is an outstanding person, has excellent customer service, and builds awesome uppers!

EDITED TO ADD: Retro Arms Works doesn’t do advertising. It’s literally been word of mouth and reviews from people who have used his services. I get nothing out of this other than helping out a guy who takes great pride in his work. One other thing I will add, there is in a fact an off menu list of things that can be done, I highly recommend you ask for the “magic”.


I’m not much of a “reviewer” of firearms and/or builds. I just kinda go with what I like.

A few weeks back I received my MK12 MOD1 upper from High Caliber Sales. This puts me at 5 MK12 and 1 RECCE upper. Yes, I really do like the SPR.

Within that time, I began contemplating I need to update at least on of my MK12 uppers. To what? I haven’t the slightest clue. Parts and pieces pretty much can’t be found in stock. The manufacturers that I like to use have no idea when they’re going to be available. The company I have used the most has really just went and shit the bed with their changes and quality (Colt).

I began searching for upper receivers. Finally hit pay dirt with Weapon Outfitters. They had uppers in stock but I don’t know who any of them are. I only recognized 1 name out of the dozen or so that they had (Aero). However there was one upper that caught my eye and I focused on that one. The only reason for that focus was the aesthetics of it. The lines were great, color was deep black, port door was a minimalist type. It just looked awesome.

Off to the net to search for V Seven…….

Once I read up on them, where they came from, who they worked with, their attention to detail, and the material they use; I bought 2 uppers, 2 rails, and a barrel. For those of you who haven’t used V7 parts, check them out. The machining, build, lines, material are some of the best I’ve seen. Yes, I’m an aesthetics guy, but I also like function at the top.

I took one of my older, less used, put away for emergencies MK12 uppers and came up with a concept. Now to look for some one to put it all together. Sure, I could probably do it, but with my OCD I wouldn’t be happy with the build. Scopes and optics mounting, no problem, staking a castle nut, no problem, building an upper……meh.

Retro Arms Works - John Thomas was the talk on a lot of different gun forums. Some I’m a member of and others I just peruse. Doing some googling, I found hundreds of positive reviews. I figured what the hell, let’s email the guy. I emailed John at 1813 on a Sunday and received a response at 1915 that same day.

I gave a list of what I would like to have done, John confirmed everything with me, let me know his capabilities and what he offers. Sent me a price list for my build request and everything was set in motion. This whole thing took less than 10 minutes to iron out and get setup.

Parts package was sent 6/22/2021, 2 day service USPS. It actually got there a day early. I’ve read a lot of reviews about the fast turn around times with RAW. Some of the comments I read I was kinda like…nah that’s BS. Let me say that the package was received on 6/23/2021 at 1300ish. I got the notification at 1615 that my upper is completed and in the mail on 6/23/2021.

I had particular requests with this build, John didn’t miss a beat. This was my first time using RAW, and the experience has been absolutely awesome. There’s another package on the way for a build.

This build consists of: V Seven GI upper, V Seven keymod 16.5” rail, Douglas SPR barrel, Deadair keymo muzzle device, Colt BCG, Vltor CH, ATLAS bipod, KAC BUIS, and Nightforce 2.5-10x24 MOAR in an A496 mount.

Pictures because I suck at reviewing…….

What made you decide to go Keymod?

No real reason. I have Mlok and keymod rails and never had a preference. I guess they both just work for me.

Thanks!

I’m really liking the rail. Small diameter, feels exceptionally solid, low deflection when loading my bipod.

I also like the look of that rail, especially how the Pickateny is scalloped, that is bad ass.

That’s what caught my eye when I saw the upper, that and the port door.

The attention to detail on their parts are solid. One example being the dry film lubricant used inside the upper. One of the most uniform applications of that I’ve seen.

Nice rifle. I mailed out a barrel to drill and mount an M2 front sight base to Retro Arms Works this past Monday and got it back to today. Very quick service and excellent work.

Congrats on a very nice and well thought-out build! Be sure to follow up once you've put some rounds down the tube.

Also have nothing but good things to say about John Thomas - excellent quality, turnaround time, and prices, and a pleasure to deal with.

Thanks! Hopefully range day tomorrow. I know this upper shoots an inch at 100 when it was in its MK12 setup.

Got some range time today. It was an okay shooting day, probably could’ve done better. A few strings I wasn’t taking my time and definitely pulled some shots.

Confirmation zero for KAC BUIS at 50 yards, 10 rounds MK262.

1st five round group (11 o’clock) at 100 yards with Norma .223 77 grain BTHP. Groups at COM were after adjustments and attempting to fine tune. I pulled the round on the far right. Mistake was made on windage adjustment, my 2.5-10 is .25 MOA at 100. I’ve been used to .5 MOA for adjustments and forgot to take that into account.

https://i.imgur.com/EDryHOo.jpg

15 rounds of MK262 at 100 yards. I pulled 2 of the rounds low left.

https://i.imgur.com/mC2vEE4.jpg

Group at 6 o’clock was 5 rounds of MK262, shot at a fairly quick pace. Group COM is 40 rounds of Norma .223 77 grain BTHP. Group above COM is 5 rounds of Norma. Top group is 5 rounds MK262 shot at a moderate pace.

I need to get more ammo and some more range time.

Build number 2 is on its way!

This build consists of V Seven GI upper, V Seven 15” enlightened key mod rail, V Seven 16” mid length gas SS polygonal 1:7 twist barrel.

I’m going to be using this up as a Jack of all trades if you will. 0-500 yards, light mount, bipod, 1-8 NF. CQB and moderate range shots should be absolutely doable.

I’m hoping USPS doesn’t screw me like the last delivery…new build should be here tomorrow.

A couple quick pics of this build…

I tried to get the pinned GB in there. I think the shadows mess it up.

I like how the scalloped upper and rail interface.

https://i.imgur.com/5yjp3DJ.jpg

I like the slope of the rear of the upper. Not only is it aesthetically pleasing it is functional in that it allows easier deployment of the rear sight. I’m able to get my thumb under the rear aperture and flip it up rather than pinch the sight and pull it up. Small thing I know, but I like it.

The port door is awesome. It and the scallops are what caught my eye. This door is a little different in the fact it is not captured with a C clip like a standard Mil spec post door. The rod slides through the door and spring assembly and is captured by the rail. Something I like about it because no more fumbling around with that tiny C clip. Pull the rod, replace the door. Done.

Thanks Dave. That's a hell of a nice rifle and your photography is top notch as well. I can't wait to see the next one.

One thing to keep in mind with this rail and barrel combination…

If you’re using standard, heavy duty type QD sling mounts, they will not work with the QD points built into this rail. The QD loop touches the barrel when trying to install it. I believe the Douglas barrel diameter is .750 at the GB and comes up to .850 towards the chamber.

Easy fix, I ordered an IWC keymod sling mount.

Hey David, long time, no talk to. Glad to see you are still in the game. This new build looks great. I will attest that JT does great work and his turnarounds are extremely quick. I have had to slow down building ARs. I had 47 of them and have whittled them down to 39 plus my KAC SR-25. If you ever come back into Pensacola, give me a shout.

James!!! We may be down that way next year.

You should trade me your SR25.

The only major changes to this build are the barrel, light, and trigger.

I wanted this one to be a more modern RECCE style rifle. The barrel is a 16 inch, 416 stainless, 1:7 polygonal twist barrel with a pinned gas block. 15 inch keymod rail, V Seven GI upper, surefire light, atlas bipod/hawk hill custom cleats, Geissele SD-C trigger, SOPMOD stock, and Nightforce 1-8 F1 capped.
