Parts to finish your Chefur Custom Krink kit
Posted by Chefur on Dec 4th 2023
Looking at buying one of my
reproduction AKS-74u kits?
Here's a few different routes you can take for completing the kit!
First off, the basic parts that are not caliber specific:
- Trigger guard, magazine catch, and selector stop plate: The best value is This trigger guard + mag catch from WBP and this selector stop plate.
- Recoil spring assembly: The best value is this new one from WBP. However, any surplus ones will work, including AKM, RPK, Type 3, AK-74, etc.
- Pistol grip nut and screw: AK-Builder has them for the cheapest
- Trigger group: Highly depends on the users preferences. The cheapest ones are $25 from Palmetto, but I do not have any experience with them.
- Safety selector: The cheapest is Surplus Romanian at Rifle Dynamics for $15. Alternatively, AoA has new production WBPs for $28
- Handguards: Kvar has polymer sets for $110. Contact Combloc Customs if you need a set of wood before mine are finished.
- 4.5mm stock: I have Russian stocks here. Kvar has polymer side folders for $120.
Total for the cheapest route: $303.99
5.45x39
Receivers:
The AKS-74u receivers offered by Childers, Recreator, and AK-Builder all fit my kits.
These range from $94.99 to $150+.
Route 1: Surplus Components
This is my preferred method for 5.45x39.
- Bulgarian AK-74 front trunnion and bullet guide: These are getting harder to find. They can be had for about $250 on Gunbroker and AK Files.
- Bulgarian AK-74 bolt / Polish Tantal bolt: These are fairly common and run about $240.
- East German AK-74 bolt carrier: For whatever reason, the EG carriers are the most common. This seller has a lot of them and they're in NOS condition. - $145
Please note that the while the Polish Tantal is mostly AK-74 derived, it is not fully compatible.
- Bolt: The firing pin retainer pin is proprietary on the Tantal. Otherwise they are the same as AK-74.
- Carrier: They have a flat surface where the carrier strikes the front trunnion and are not compatible with AK-74 front trunnions, which have an angled surface. They will chisel into each other.
Tantal trunnions and carriers are both compatible with my parts kit, but must be used with each other.
This route uses the 22mm barrel option and AK-74 gas piston option.
Total for surplus components: $645
Route 2: WBP 5.45x39 Bolt, Carrier, and Trunnion
WBP Bolts, carriers, and front trunnions are all proprietary.
If you use any one of them, you have to use all 3.
Please see here for my notes on building them, as they are strange.
- Front trunnion - $89.99
- Bolt - $79.99
- Bolt carrier - $89.99
This route uses the 23mm barrel option and AKM gas piston option.
Total for WBP: $259.97
Cheapest option for 5.45: WBP BCG and trunnion, AK-Builder 80% receiver, cheapest route of the basic parts at the top: $658.95 total
5.56
Barrels:
At the time of writing (December 2023), I have ordered both 22mm and 23mm barrels to offer alongside my kits. They are estimated to be available the second week of January.
If you need something right now, there are only two barrel options.
- Arsenal SLR106 barrels. These have a 23mm barrel journal and will work with WBP 5.56 kits or the Galil-AKM hybrid.
However, the hinge block journal diameter is a thicker spec for milled receiver profile components. This diameter can be turned down easily by a competent gunsmith or machinist. - Obstreperous / Luckypen: These are standard AKS-74U spec and will work with my kits.
He offers them in 22mm and 22mm oversized. To use them with a 23mm trunnion, such as a WBP 5.56 or Galil-AKM hybrid, you will need a competent gunsmith to sleeve it for you.
Route 1: WBP 5.56 Bolt, Carrier, and Trunnion
WBP Bolts, carriers, and front trunnions are all proprietary.
If you use any one of them, you have to use all 3.
Please see here for my notes on building them, as they are strange.
These use AK-74 pattern magazines, such as WBP, FB Radom, Circle 10s, or surplus 5.45 magazines with a Pod Arms conversion follower.
- Front trunnion - $89.99
- Bolt - $79.99
- Bolt carrier - $89.99
This route uses a 23mm barrel (not yet available for 5.56, on order) and AKM gas piston option.
Total for WBP: $259.97
Route 2: Galil-AKM Hybrid
This route is perfect for those that already have a beater AKM kit to cannibalize, or if you just want to run Galil mags. I have completed one of these now, and I'm starting on a second.
- AKM front trunnion. Anything AKM spec will work here. The new production WBP 7.62x39 ones are very consistent and work well. - $89.99
- Galil bullet guide. Hillbilly Firearms has them - $46
- Galil bolt. These are all over the place secondhand. They can be had for as little as $50. The average cost is around $70.
- AKM bolt carrier. Any AKM spec carrier will work. The new production WBP AKM carriers have some QC issues. Average price for these is $90
For the receiver, any 7.62x39 spec receiver will also work here as the Galil magazine uses an AKM spec magwell, despite being 5.56. Childers, Recreator, WBP, and AK-Builder receivers all use untrimmed ejectors that are long enough to be used for 5.56.
This route uses a 23mm barrel (not yet available for 5.56, on order) and AKM gas piston option.
Total for Galil-AKM Hybrid: $295
Route 3: Surplus and FB Radom
This route is one I have experimented with multiple times and had good success.
These also use AK-74 pattern magazines, such as WBP, FB Radom, Circle 10s, or surplus 5.45 magazines with a Pod Arms conversion follower.
- Bulgarian AK-74 front trunnion and bullet guide: These are getting harder to find. They can be had for about $250 on Gunbroker and AK Files.
- FB Radom 5.56 bolt. These are AK-74 spec, but with a slightly deeper bolt face. You will need to trim either the chamber face of the barrel or bolt face, depending on what barrel you use. - $179
Please note the firing pins are proprietary. I would recommend picking up a spare if you go this route. - East German AK-74 bolt carrier: For whatever reason, the EG carriers are the most common. This seller has a lot of them and they're in NOS condition. - $145
This route uses a 22mm barrel (not yet available for 5.56, on order) and AK-74 gas piston option.
Total for Surplus/FB mashup: $574
