416 10.5 upper on Colt M16 Lower

I haven't run a 416 upper on my M16, but I have talked to a couple guys who have and they seem to work just fine. I've run a couple LWRC uppers and a Adams Arms upper so I've got a little experience with piston uppers on the M16 platform if you have any questions that relate to that.

The bottom line for me is that i wouldn't hesitate to run a 416 upper on my '16 if they didn't cost 5K. For that kind of cash I could buy an upper, suppressor and a lot of ammo.

That is certainly a lot for the upper.
I was under the impression that they were about $3500.

You might get lucky. One just sold for about that amount, but the auction wasn't even up for 20 hours. You're looking at $4000-$4500 pending condition.....if/when one comes available.

416's run like a dream....never had a jam yet and I dont even clean the rifle alot....watch sturm, gunbroker, subguns and HK pro if you want one. they do pop up for reasonable prices from time to time

I have a HK 416 upper on one of M16s and it runs great. The rate of fire is slightly slower, but I actually like it. I use a YHM suppressor on it to tame the sound and flash from the short barrel since I primarily hunt hogs with it. I have probably shot 2000 rounds thru it and have never cleaned the piston assembly, it’s on my to do list.

They are expensive!

They sure are an expensive upper but well worth it. From what I have seen as long as you change the buffer spring and buffer on your M16 you are good to go!!

I have run my HK 416 10.4'' upper on my factory Colt M16A1 lower with the stock colt buffer and spring without any problems. Runs like a champ, no jams, no failure to feed, fire.

Thank you all for your replies.

Hey bro. I just bought a 14.5 416 upper from a guy on gunbroker for $2500 shipped. It was at about 90% with minor scuff marks mainly on the rail. It was a steal I think. Not as nice as my 10.5, but really good for someone with a RR M16. Pm if you want me to e-mail him. Not sure if he has anymore, but worth a try.

$2500 really, that is a steal.
Lucky you

is the 416 all that much better than a LWRC?

I've had the privilege of running the 416 against Colts and LWRC and the 416 performed the best. It's just built like a tank.

Marine0303 would you please elaborate on why you like the 416 better than an LWRC.

Of course, this is just my humble opinion, but through a week of shooting, the 416 experienced no issues, where the Colt, SCAR-L and LWRC did. Beyond numerous daily drills, we also chose not to perform any cleaning of the weapons. Obviously, we expected the Colts to develop stoppages, but the LWRCs and SCAR-L did as well. The 416s kept running. Accuracy on all were about equal, but even in the 10.4 inch barrel, and in full auto, the 416 felt like the easiest to shoot.
This was not an official or scientific test. We simply handed out several models of each gun to our guys, ran them through drills, observed and then asked for their feedback. In the end, when asked which weapon they would want to take on the next deployment, the majority (including me) chose the 416.

Thank you for the explanation, I am assuming that the LWRC was a 10.5 in barrel ?

Some were the 14.7 inch barrels and a few were the PSD model with the 8.5 inch barrels. Not trying to take anything away from the LWRC, just explaining what the result was from a week of hard shooting. I doubt you are going to put your gun through that kind of work load and lack of maintenance, so the LWRC should be suitable. You are on an HK forum though, so expect members to be leaning in that direction, if not drunk on the kool aid.

You are absolutely right, I will never put any of my weapons to that kind of test.
I am very happy with my MR556 and the 416 is on my list of must haves.

Just one of those lucky breaks, but chance favors the prepared mind. Keep searching constantly, and you will eventually come across a deal.
