(links) Belt-fed 22s, AR hybrids, and 80 percent receivers

...And other cool gun stuff.  These are the things that I missed in the eight months I was in Africa in 2019.

1. Belt-Fed AR upper receiver in .22lr - LithocoreX
Saw this on Reddit - Apparently a company called LithocoreX has purchased the machinery and tooling for building a .22LR belt-fed upper receiver which was originally owned by the now defunct Lakeside Machining.  On sale for $1300.  Not a bad deal considering that the next cheapest belt fed is the 9mm AR Beltfed from Freedom Ordnance at $1600.

Problem is that there is not too many good things about the company itself.  From a thread Uzitalk:
This is probably another one of those branded technical packages that keeps getting bought and resold by smallish machine outfits trying to expand their production line. Essentially the leftover stock and tooling of other failed commercial ventures. The Calico properties have been in this boat for years. Just keeps getting passed around.
Lengthy discussion on AR15.com here.  Note the date, August, 2018.  Some members state they didn't receive the item until December, and some saying February, which isn't too unreasonable for a small gun company.  Apparently some are approaching a whole year of waiting.

Status Update - Current status of shop.  Seems like they're highly disorganized and haven't even bothered to update their status page in months.

2.  Bren-AR hybrid
WeaponsGuild user Mauser98 has created an upside down AR15.  Also known as the BRAR by the creator (BRen AR-15).  Basically an upside down AR15.   Consists of an upper receiver (formerly a lower), a middle receiver (formerly the upper), and a new lower receiver frame which houses the fire control group.  A top-mounted weapon would be great for mounting on an M2 tripod or vehicle mount since the magazine would be easily accessible and you would be able to place the gun pintle close to pistol grip.
3. Side-fed AR15 (Not an FG-42)
Keeping up with the World War 2 theme of weirdly-mounted magazines, user Skib on the the WeaponsGuild forums has created a side-fed AR15.  Unlike the previous Bren-AR, this does not use a fancy mill and instead is constructed using more primitive methods using hacksaws, a Dremel, hand files, and welding.  It is rather impressive work.

Also check out this video from ForgottenWeapons about a similar project created in the 80's of a side-fed AR15.

4.  80% Mossberg 500 Pump AR15 hybrid
https://logic80.com/product/cs1280preorder/ Kind of kicking myself for not snagging one when they were taking pre-orders, but now looking at the process of finishing these, it looks a bit complicated and machine-heavy in construction and Mossberg 500's aren't really something that's high on my priority list of guns that I want to own.

5. 80% Sig frames and inserts
I've seen several online stores selling an 80% Sig frame insert for Sig P-320s and also P-22X frames.  I am 100% unfamiliar with any Sig Sauer firearms, but the more options for the 80% market the better.  This insert is called the MUP-1 - Modular Universal Pistol.

Here's a really good tutorial for the MUP-1 frame-insert.  Seems a lot simpler compared to the 1911 or even the P-22X which requires all sorts of specific jigs, tools, and dies and hand-fitting - specifically frame-rail cutting of the 1911/P-22x which, to me, looks like a real pain-in-the-ass to do.


Also there is an AR-15-like weapon that utilizes a Sig Sauer pistol frame insert that is used as the fire control group, so all the more reason to go with the Sig P-320 kits.

6. 80% ASR HomerBuilder's Kit - 
These ASR 80% kits have been around a while, but the reason I avoided it all this time is because it requires threading a receiver tube to take a buffer tube.  I don't know about you, but threading a tube requires precision, and hand-threading a tube straight is difficult for the average garage work-shop.
