My Defgunz receiver and C  parts kit from HK parts runs most anything (223 or 5.56 PMC, Winchester, Federal, IMI, and some of that cheap brass Monarch stuff they sell at Academy Zero issues.

Same with my S5 TACTICAL receiver G36c build on HKP parts kit. First range trip it choked but when I properly oiled it it functioned perfectly and has eaten some dirty rounds. That G36c has turned into my favorite rifle.

Have seen this mentioned in a few places now including by Tom B. on the G36 FB group recently, but it's interesting the overpressure flutes are no longer milled into the barrel extension on the G36C parts kits (you can see an example in HKP's assembly video).  I checked w/ S5, and they said their complete rifles/pistols still have the flutes milled in, so it seems to be specific to the C barrels.

I wonder if they were deemed unnecessary, or if the mfg is trying to increase reliability with lower pressure ammo by sealing up the chamber, or if it's purely cost-cutting, or a mix.

Got my S5 G36K pistol today. Love how light it is. I swapped over to a AR Magwell and installed a 1913 adapter at the rear. Brace arrives Thursday.

Defgunz was supposed to release an aluminum receiver for the G36 by now.  I've given up on that happening and just bought a plastic receiver from S5.  Here is my G36Kish rifle.  It has a 16" barrel.  I already have a G36C SBR, so wanted to keep this one a bit longer.

Cool setup. What barrel is that, and flash hider?  I have the S5 rifle, but did not think the bayonet lug could be mounted to it. Could you give us a rundown of your build. Thanks
4/13/2026 10:24:34 AM EDT
[Last Edit: 545Fan][Edited] [#15]
Sure.  It's an S5 receiver with an HKParts parts kit with 16" barrel threaded 1/2x28.  I also bought a seperate flash hider and the bayo lug and roll pin from HKParts.  The flash hider is an A2 compatible flash hider I use with B&T cans with A2 mounts.  The scope is an Arken x1-8 LVPO.  The forearm is a K model and came with the parts kit.  The rail is a B&T rail, I believe.  It's aluminum and has no backup sights.

Anything else?

@545Fan

Does the bayo lug literally just roll-pin on to the bare barrel and hold just with friction, or does the barrel need a drillin' like an A2 FSB?

I have the bayo lug, waiting on my S5 shipment (they are quick to take money but I'll be damned if I've heard a peep since).  

I have zero idea if my bayo lug will mount on this.  No clue if the 4-prong FS will accept the Bayo, too.

I just pounded the roll pin in with a roll pin punch and a hammer.  The one end of the pin was pretty ugly when I was finished, but I cleaning it up with a dremel and painted it.

Shot mine today for the first time

100 rounds PMC 223

5 magpul mags

No problems whatsoever, shot it kneeling braced to sight in and standing offhand for fun.

Everything worked great, sights easy to adjust but needs tools.

Shot OK, will be better once im used to it but no worries.

Nice recoil impulse, fun gun, will try an optic next time.

Its a keeper!

She's in.  Optics are on, but had to order more appropriate screws.  

C-stock en route.  Bayo lug on hold.  That's gonna take shims and a smith.

Sweet! Did you find a G36C factory buttstock in stock somewhere? I've been looking for quite some time...

Atlantic's email flyer last night showed they had G36 Carry Handle scopes in stock -FYI

Having used one, they are not "great" optics and aftermarket offers better optics for the money, but these are often sought after.

Neeest member of the family.



This thing has been the bane of my wallet’s existence for the past few months.  Couldn’t find a parts kit, so I went the individual parts route and boy, did I pay for it. Literally!



The only plus I can find is that I know for a fact that every part, minus the receiver, brace  and a few screws, is original HK; no GSG-9 parts here. I even have a couple original HK magazines in the mix.

I will ultimately drop paper and have it SBR’d. But I am so thankful that I’ve finished putting this German Money Pit together.

Shiet! With the kind of money I spent putting this thing together, I could have bought a ful MR556A4.
