A few weeks ago I found that I had enough odds and ends around to assemble an upper but no upper. I promptly took care of the latter issue with an upper receiver from Black Rifle Depot. I shopped for price only and they had the best prices a week ago.

I also have a Spike's Tactical .22LR adapter so that will be the BCG and I'll dedicate the rifle to .22LR. Rear sight is a Matech, the real thing I think but it's been in the junque' box for some years now. Barrel nut, weld-spring, and circlip were also just gathering dust.

Gas tube was pinned to a low profile gas block but I wanted to use the railed one shown in the pictures. The quad rail gas block, yet another odd-ball item picked up whenever. Handguard has been purchased and it's a Magpul MOE.

The barrel is a Ballistic Advantage that I tried to sell in the EE but had no nibbles so that along with a Noveske 'Flaming Pig' attachement rounded out things.  Twist is 1:7 NATO chambered in 5.56. Oh, 14.5 inches long. As I have an SBR stamp no worries there.

Nothing special but shows what you can assemble after years of messing with these rifles. Fun way to spend the afternoon too.

I came across a barrel nut and a FSB in my stuff.......yep.......I know the pain.

I'm doing a 22LR build from spare parts myself...got a slightly damaged upper that will be usable for 22LR, and a really nice Spikes barrel with a damaged barrel extension that will still work with the 22LR conversion kit.

Not ready for pictures just yet but will post everything once I get more done on it.


Have fun with the build!

Soon you will be in meetings and on a 12 step program........

1:7" twist for a dedicated .22 LR?  Post some groups...

BKings had stripped uppers even cheaper.

Do I detect a hint of sarcasm here?  

As to the twist rate it is what I had. If it is too much, I did zero research, I'll use it for 5.56. A BCG is all I'd need. Or heck, maybe even sell the whole thing since I've got another .22 in the AR format.

Thanks for the warning on the 1:7 and .22lr. I guess I need to do some reading.

It just depends on what you want from it.  If just ringing steel @ 25 yards and in, it will be fine.  If you want to headshoot tree rats @ 50 yards you will be left wanting

99% finished. Handguards bought here from the EE. I like the gray for a change.

I guess I need a forward assist assembly and a dust cover. I have the cover but no pin or spring. No rush on either one.

I also used a Bushnell red dot that I found in the sock drawer and removed the MATECH.

If you're just using it as a .22 you don't need the FA, nor really the dust cover.

Did you install a spacer between the handguard cap and gas block?

I did. I had a spare round one in the junk box. EDIT: Maybe I misunderstood what you meant. I used a round handguard cap only. BBL-HG Cap-Gas Block.

Finished the process yesterday. I opted to go ahead and get the forward assist and the ejection port cover from Damage Industries. And I bought a BCG instead of using the Spikes Tactical .22 conversion group. Everything else was either on hand or from EE or the online folks. If you don't count all the parts I had squirreled away I think I spent about 150-dollars. Doesn't matter as it was a fun and simple project.

Hmmm...I see I have a Surefire CAMFA556K flash hider that needs a barrel...

Thanks for sharing.
22lr from my 16" 1:7 does about .5 moa at 25 yards.
Some may call bs, but I can get tight groups if I do my part and take it seriously.
I don't necessarily think it would be a 2 moa at 100 yards, but I wouldn't be shocked if it were. I haven't tested it that far.

You’ve inspired me to take some inventory and see if there’s enough lying around to round out a new rifle.

Cool build.

Good work OP.

It only takes a small amount of spare parts for me to get my gun building wheels going.

I had a spare Larue 12.0 handguard hanging around for a while and when I came upon some Centurion barrels for $140, well you can imagine the rest of the story.

This seemed to coincide with my 45th birthday as well, so I informed Mrs. M4ger that I was going to build another rifle

Seed parts and EE deals. Never fails.

love it when there are always parts around to assemble another one :)

Half MOA at 25 yards.  I don’t think so.  1 MOA at 100 yards is a hair over an inch.  1 MOA at 200 yards is a bit over 2 inches.  Conversely, 1 MOA at 50 yards is ½ inch, and ¼ inch at 25 yards.  You’re saying your rifle shoots ½ MOA at 25 yards?  That would be ⅛ inch center to center, or basically a one hole group.  Not buying that.  Unless you meant ½ inch at 25 yards which would be 2 MOA.  THAT I’ll believe.

I don’t know how mine will group yet, just had time to check for function with the conversion kit.

Once I get the FF rail set up properly and have it scoped, I’ll check the grouping.

I really do hope it shoots at least acceptably as some of its made from salvaged parts that can’t be used with full pressure 5.56 NATO.
