AK Project Help

My son turns 18 tomorrow.  He is dying for a 5.45mm AK75 build, but wants a bit of the AK105 look/feature set.  I have a local builder available to help (Troy @InRange C2), but getting the parts together is my hold up.  The receiver is easy, and I get the 922r stuff, but I'm struggling to figure out a few things.

The kits have dried up (duh, Matt) and it looks like a Bulgarian kit ($350-450) might be a good start point.  New US barrels are available, so that's not to big a deal.  I guess I'm wondering how to approach this to avoid squandering cash.  The boy wants:

  • AK100-series side-folder triangle stock (less angle, more straight-line versus older triangles)
  • One-piece FSB/gas block
  • Standard threaded muzzle, versus AK100 series where FSB/gas block is threaded
  • New AK100 series rear sight block
  • Barrel to minimum legal length with fixed FH, or possibly SBR'd

Since so little of a parts kit will be used would it be better to just try to piece this together?  All told, will be providing new receiver, barrel, rivets, ALG trigger group, Krebs safety, flash hider, furniture, likely a different top cover, FSB/gas block combo, rear SF stock and trunion, rear sight block.  My builder has most of the misc small parts on hand.

Make sense?  Any help or guidance appreciated.  I dug into the big, modernized AK thread, but the info is getting dated and the pics are mostly gone.  Anyone got a line on a parts kit?

Original Post

really all you are not using from the kit is the stock, gasblock, and front sight base.  So I would say that the parts kit is still probably the best way to go. 

GBC-13 front sight/gas block:

I would use a Green mountain barrel or a Bulgarian one (k-var might have them). I like Childers receivers. AK-builder has side folding stocks with trunnions.

Oh, for 922 compliance you will probably need a US made trigger group: ALG, G2, Fime Group, etc. 

74 mags have gone up in price but aren't too bad still. The Magpul ones are cheaper and reportedly work well, my 7.62x39 pmags work great (but I have no 5.45 anything).

comblock grips are small so I would recommend a Magpul or US Palm (if you can find one), which will also help with 922 compliance.

So where do you go for AK part-receiver compatibility info?

Me for one.  European except for the Yugo/Serbian are 1mm sheet steel and almost anything will interchange for a basic rifle.  Things start to get a little different if you are looking at folding stocks or the Hungarian rifles.   Yugos and Chinese are 1.5mm sheet metal.  Except the M92 series.  They are back to 1mm.

AK74s have mag well differences from the 7.62 guns.  Sidefolders have a different angle on the rear of the receiver and a different trunnion.  A few other things.  Romanian AK74 variant has a slanted gas block, all others are 90 degree.

Chinese are 1.6mm. Yugos with bulged trunnions are 1.5mm as are RPKs, which also have bulged trunnions.

Chinese barrels also have smaller journals so they require proprietary front trunnions.

Yugo barrels are AK47 thickness as opposed to AKM, and yugo furniture is all proprietary.

AKM and AK74 furniture is interchangeable. The handguards and fixed stocks.

Triggers are pretty much universal, as are 7.62x39mm and 5.45x39 magazines. 223/5.56 AK mags are generally only good for country of origin guns.

Bolts and Bolt carriers are often in interchangeable (within caliber) but need to be headspaced .

Honestly you could probably find a used Arsenal 104fr for less than building one yourself.

Or pay a bunch for a Vepr

Thanks for the replies, I knew we had some knowledgeable folks here.  Agreed that a complete gun is likely a better/faster route, however this is as much about him "learning" how the gun is built and being able to help with that process as it is about having the rifle.  Sounds like I'll pick up a kit and start piecing the other stuff together.  Childers vs. NDS vs. McKay for receiver?  Any difference and does anyone make it with the correct AK100 series left-side folding stock cut?

Planning a new US barrel and ALG trigger.  Saberworks block is one we were looking at.

I'm at work and my computer blocks most gun related sites, but I believe NDS makes a receiver cut for a sidefolder.  I think they make them in 5.45mm for the AK74, AND 7.62 if you want a "Khyber Pass" build.

Childers makes the 74 receivers for either a 4.5mm or 5.5mm folding trunnion.

With either a Polish Radom blank or US made blank.

Polish: http://www.childersguns.com/CG2-Polish-74-Receiver

US: http://www.childersguns.com/CG4-US-AK-74-Receiver

If you use a 5.5mm you can use one of these unique stock sets: https://www.legionusa.com/ak-1...-wood-stock-set.html

 

Or you could full crazy and build a milled 74: http://www.cncwarrior.com/Mill...Receiver-p/23549.htm

underfolder: http://www.cncwarrior.com/AK74...erfolder-p/23542.htm

The milled receivers are expensive options though.
