Home Forums Hunting & Shooting AR and Tactical Rifles Putting together a 'Pandemic Build'

So this will be an M4-esque but in dedicated 22LR.

Barrel is ordered from CMMG, not sure how soon it will ship....might take a few weeks?

Anyhoo, figured I'd take the forum along for the ride.

Here's the barrel I'm building it around,

https://cmmginc.com/product/barrel-assembly-16-1-m4-4140cm-sbn-22lr/




I already have a CMMG 22LR conversion BCG, so just need to swap the chamber adaptor for the collar. Have some Black Dog 25-round mags, and ordered some Black Dog 15-rounders for a more compact feel.

I'll update as things come together.

Obviously this will not need a gas tube for function. I'm thinking of putting one in there anyways, to lock the barrel nut in place, and provide positive index for handguards.

Any thoughts from those who've already been down this road?

Ahhh... the 22lr "Sprorting Chamber"

Looking forward to the build.

I like taper pins,but hate M4 hand guards. I'd saw the block/sight like always and stab a FF tube aboard and never look back. I'm always happy to use a real barrel nut too. Hint.

I drive a dedicated Peezer 22LR,to compliment my Garrow Hummers and Franklin Whizzum. It's a handy bitch and rather light,all things considered. Have contemplated converting it to a side folder,beings there's no buffer or spring requisite. No gas tube for me.



BD 15's expressly,for me and CMC trigger....................

Side folder !!

You'll like it.
Mine doesn't lock folded, the only thing I hate about it.

Montana Marine, Stick & others with dedicated 22LR uppers,

I'm pretty interested in these builds and would like to do one. My main concern is what kind of 50 yard accuracy they get and reliability.

Thanks for posting this.

Jerry,

Can't speak for the builds, but I have a PSA 20" 22 LR upper that's very accurate from 25 to 100 yards (haven't tested past that). like 1-1/2" at 100.

I purchased this PSA uper about a year ago, and using Blackdog mags, have had zero malfunctions using good ammo.

I really like having a 22lr in an AR platform that has the same feel as a 5.56
I put a Sig red dot sight on mine.

Thanks for all the info guys.

Nice looking setups.

I intend to keep this one along the lines of the M4, and if it will hold around 1" at 50 yards that will be fine with me.

The CMMG conversion BCG I have already, is only good for about 1" at 25 yards. Of course that was to be expected with a chamber adaptor in an oversize bore with the wrong twist rate.....grin.

This is the direction I'm headed. Something very similar to my M4 style 5.56.

Partial pandemic build... LOL. It's a BCA side charger16" 1in8 5.56 with 15" ff handguard. $250ish. I know, I know....

Will have another lower assembly with a fixed butt, however, shipping seems to not be a priority with the vendors involved.

Wanted this longer sight radius and digging the way its coming together. Will be in enough cheaper than the FN to matter to me, which I have a 1-4 scope on....


Next?

^^^ Nice!

Got a shipping notification from CMMG today. So it looks like they are not swamped too badly.

Dang, got a lower and upper sitting around and can't decide on what to build. Might just be a 22LR pistol after seeing these. I have not heard of the BlackDog mags Going to give them a look.

The Black Dog mags are what CMMG includes in their conversions, but they are the long ones, 25 rounds (10 for CA and other freedom deprives places)

But you can get the shorter BD mags that hold 15 rounds. They are the size of a 20 round AR mag.

I have three of the long 25-rounders on hand from my CMMG conversion unit I bought some time ago, but I ordered three more of the 15-rounders through Midway.

The 15-rounders arrived yesterday from Midway. I test-ran them using the CMMG conversion adaptor in a 5.56 barrel. They are a nice size, and ran perfectly.

This is a 10.5" 5.56, with the CMMG 22LR adaptor and 25 round mag.

Got the two lowers today.... Another "pistol" methinks.

5.56 or...?


I kind of want to put together a 300BO upper at some point. I like the looks of this 12.5" barrel from CMMG,

https://cmmginc.com/product/barrel-assembly-12-5-mr-4140cm-sbn-300-blk-wlpgb/

I took the easy way out. My first venture into AR pistols and the 300BO cartridge is going to be a Springfield Saint Victor that should arrive at my local Sportsman's Warehouse in a couple of days. I have been scrounging scarce reloading accessories and components, so ammo will have to suffice as my "build."

Sounds nice, I'd be interested to hear what you think when you get it up and running.
