Maccabee Defense SLR information and updates

Finally managed to put the first 100 rounds through mine last week. Middle of the road build - IBI 223 wylde barrel, Geissele SSA-E trigger, mix of Geissele/BCM/Magpul/Phase 5 parts.
Zero failures, everything worked well. The front takedown bolt stayed tight, and I saw absolutely zero wear anywhere when I pulled it apart to clean.
My gen 3 Magpul 5/30 and CPD pistol mags all seated and dropped free with no issues. My two Hera mags would only drop free when fully loaded. Bolt catch worked on every mag.
Crappy bulk AE 55gr grouped between 2.2-2.5 inches at 100 (5 shot groups), roughly 0.5" better than it did in the WK with the same scope and trigger, but the SE isn't great for precision shooting. Didn't get time to put better ammo through it, but it will be minute of coyote to 300 yards on crappy ammo, which I'm happy with. Ryan at IBI was adamant that his barrel will do better than moa on good ammo, assuming I can do my part. Only time will tell.
Considering the issues some have had, including an owner with a serial number within 10 of mine whose receiver was a mess, I'm pretty happy with it. Mine had an undersized gas tube hole in the upper, but the machining was otherwise fine.
Now to figure out what to build with my spare upper. Was 80% decided on a light-ish 6.5 Grendel build, but TNA bringing in 458 Socom barrels has my interest. I may need a spare spare upper...

Who’s received rifles from Gunworx’s second preorder? Anyone?

I'm still waiting for a non-refundable parts kit from then that was originally estimated at a 6-8 week wait. Now supposedly coming in line with this mysterious second pre-order. Haven't had any follow up, no explanation on why it's been over a year and they still haven't got the kits together yet. And yet they were perfectly fine to take my money right away.
 
There seems to be a lot of armchair speculation and little practical experience with these. Anyone want to chime in? Any issues? Round counts? etc? (build photos are always nice too :) )

Here's my latest build. It's a 7.62x39 with an IBI barrel bought from RWA. Only 80 rounds of Hornady 123gr SST through it so far for function test but all went well. More good ammo on order as I'm not going to run surplus through it.

But this build is only temporary until I get another MS receiver set to put the parts into.

I built 2 so far. I have probably 500rds through mine. Some mags are tight, some just fit, none are loose. Mine went together without issue, ran right out of the gate, second one as well but the barrel went in kinda tight, same barrel, it has a looser magwell though, mags that wont fit in mine fit it no problem. Finish is ok, ano seems kinda thin, couple machine marks. I have no complaints.

Gunworx is horrendous.

Took me 3 months to get the kit and when it did show up it was missing parts. Cancel your order and get a ALG ACT & DPMS lpk combo from brownells.

Thanks for the honest opinion. Would love to take a look sometime. I really want to do a x39 build but thinking maybe I should pre-order the ATRS set and be patient. If for no other reason than assuming I would run surplus through it and need to clean it every time, I don't want to strip the threads with frequent disassembly. I have warmed up to DI guns in the last few years and am quite fond of them now.

What BCG are you using in 7.62x39?

I picked up two more receivers, one around #570 and one near #595, BOTH of them had undersize gas tube holes. A gas tube measures .180", my receiver near #460 had a .182" hole, these two measured .169". This was measured with a set of number size drills, and I very much know how to measure something. I checked the bolt catch pin holes with the same method and they were perfect, along with the dust cover pin holes. The undersize gas tube 'cloverleaf' is a real thing. I solved the non-critical issue and am moving on with assembly.

May have somthing too do with whi they farmed the upper too. Xall of the uppers I've worked on in the last 2 months have that undersized gas tube hole. So I had to machine them
 
Just got my reciever set 6## series serial number.

I tried to install my barrel today and it would only go in a mm or 2.

I noticed/felt on the inside of the receiver where the barrel slides in that there is a raised line:
you can see in this picture:

ive been advised to put the barrel in a freezer for four hours and to heat up the receiver and then try with tons of grease.

Would lapping the upper receiver also help with fit?

Are the marks normal?
 
Man, that’s ridiculous. Even more ridiculous that they want you to fix it.
