Here’s a good place to start: HK416C build

Only negative is the proprietary carrier. I like the HK PDW stock but the Maxim Defense might have one up due to your ability to use a standard carrier.

 

Thank you for the link, reading up on it now but I am still looking for opinions on people who have been running a PDW stock.

 

The HKParts PDW stock also uses the standard 416/MR carrier.

 

I still have one more brand new full factory HK German 416C stock and handguard kit left. Comes with everything needed to fire minus the bolt head, firing pin, and spring. Includes 416C stock with internal buffer, bolt carrier, flat wire recoil spring, handguard with bolt. PM me if interested. I’ve ran the one I’m keeping for a couple hundred rounds already and it hasn't skipped a beat. I like keeping my rifle ALL HK.

 

I decided to go with the maxim CQB stock for my patrol rifle build for my patrol rifle but I may do a full C build. Once it comes in I'll make another thread for the review. I'll send a PM to you now.

 

The Maxim defense stocks/braces are really solid pieces of gear. They function well, and while they aren't exactly the cheapest option they do work, and work well. The guys over at Battle Line Defense are running them in classes and they have held up after a lot of abuse.

 

Yea I ended up ordering that one and appears to be solid. I have yet to do some drills and classes since my upper is at IGF getting work done but once it comes back I'm looking forward to testing it out with and without the suppressor

 

The Maxim stocks are also OEM for Colt and Colt Canada, though at least the Colt US Models use their own shortened carrier.

 

Everyone's opinion, advice, and guidance is welcome. Thank you.

Do not put a PDW or anything of that experimental nature on a duty gun. It affects reliability. I am sure someone somewhere will have made it work with pixie dust and what not, what HK didnt get to work, but trying that on a duty weapon?
For actually no real benefit, because if compactness is a thing, you should just use a folding stock weapon.

 

I have a class coming up where we shoot 1k+ rounds on a full day. I plan on running it suppressed half the day and the other half unsuppressed. Lots of running and gunning so I'll be testing it out. If I have any problems I'll be swapping it out and putting the stock one back on. The reason why I chose maxim for now is that there's several HK416 running their stock without issue and some members here are also running it as well. I also have several of our armorers inspecting it that day. I may get an H2 buffer and spring to run with the system as well to test out with

 

There is someone over here with a brand new A3 all kitted up with PDW. And he is kind of immediately getting rid of it. It just doesnt work.

416 are very accurate and robust/reliable, taking chances with the whole key feature of the gun for fancy, I wouldnt do it. Regarding surpressed, why ever run a gun unsurpressed if its a duty gun, after all thats how you run it on the job no?
But of course each to his own!

P.S. notice how pdw stocks REALLY conflict with ambi guns :18:

 

Do you know what kit he is running and what setup he is running with? Buffer, H1 H2, which brand etc?

I run a Surefire RC can which is a pretty big can and I went with a PDW and SBR for compactibility and lightness as a priority. I throw this in a small bag with my plates for duty.
When I deploy it's quick, light, and to the point.

 

The PDW stocks do work, so I don’t know why that guy is telling you it doesn’t. I have a few hundred rounds through mine and it hasn’t given me a problem at all. Ejection is consistent. If the gas system is tuned correctly it will not be an issue even on a 14.5” setup.

I forget exactly how many failures HK had with it in 20,000 rounds but it was double the standard HK416 which was only like 3 or 4 rounds out of 20,000 for the HK416C. I’m sure well within the acceptable margin for another manufacturer other than HK.

 

I'm still going to run it through the class that's why I asked what brand and what setup he was running. You're right that fine tuning the gun definitely matters which I'm definitely going to do. I made a thread awhile back where I fine tuned a surefire RC suppressor to work with the HK416. It took trial and error but I had the time to do it so I did it

 

I just looked at this guys ad on egun - eGun

He says it functions super. However, that is with less than 200 rounds thru it.

For a non-duty firearm to take to the range to enjoy, it looks nice and is all OEM minus the optic, BUIS and muzzle brake.
