Mrgunsngear visits Battle Filed Las Vegas "weapons durability and failure points"

[Dhena81]

Good to know I have 2 of the most combat proven weapons on the market.

The MR556 was the least durable AR type weapon along with Eotech's being the least reliable 1x optic.

Also make sure if you shoot your 16s with that Gen 2 Pmag your bolt catch clears the rear of the magazine. Otherwise your bolt will end up striking the bolt catch every time it cycles. Gen 2 Pmags are designed for a standard AR lower.

"I am issued a HK 416D, own a MR556, and have the Titan upper."

Your agency hiring?

"The Titan handguard rail takes a mallet to get off. The rail slots are out of spec. The gas block is canted. The rail height on the upper is taller than the HK so you can't use aftermarket rails without the rails being mismatched in height. I haven't shot it as much as BFV, so I can't question the durability of it. But it is no where close to the build quality of the 416 or MR556."

Never said the titan was on the level of hk fit and finish (hell, nothing except hk is), I've read about the above issues and shyed away from these uppers when the gen1s got blown out, but what these extreme uses of these guns has demonstrated is that build quality and fit and finish play little to no role in a guns basic function: Making bullets fly in a straight line where you point it.

It's narrowing the gap between the nebulous "tiers" in guns we've adhered to over the years.

We have unbiased and objective case studies showing there's essentially no difference between a RIA 1911 and a kimber, between a PSA fn upper and a Gucci noveski, or a mr556 and a knockoff.

I'd buy a HK416 in a heartbeat if they actually sold them.

I started reading the main thread and it seems that they'd rather not comment or have never tested a LWRC or a PWS piston AR.

Just a heads up to some of you piston AR guys. Personally I don't see the point over DI.

The MR556 is pretty accurate out the box with its heavy barrel and it works, so no biggie. The EoTech and the magnifier great as well. EoTech customer support is awesome, as they didn't charge me for any kind of work I needed on my XPS-3.


I don't use that pmag, I have plenty of STANAG mags I use. Thanks for the info, had no idea.

Very few semi auto HK416 complete rifles made it into Civilian hands. I also believe some had to be registered as pistol lowers, in order to get them. HKpro forum has way detailed info and better explanation than my poor attempt. There is a specific HK416/417 forum on HKpro. If you can see the pics from that link, page 38 there is a guy in the USA with a HK416D SF marked complete rifle, and page 39 there is a Canadian gentleman with a complete HK416 no D or SF marking. I've heard the completes have gone anywhere form $10k to $20k, not for the faint of heart. I think there is even one guy from CA that has a complete 416, pretty cool!!

HK416 uppers can be had, but they come at a steep premium. I've seen a few for sale here on CG, but mostly on HKPro and gunbroker. They can run anywhere between $3k to $5,500, depending on condition. I've evern heard stories of guys with AI OTB (over the beach) or newer uppers fetching $5,500+ Supply of these uppers are drying up, but can be found.

Some guys buy 416 uppers and put them on MR556 lowers, but honestly you could just put it on a regular AR15 lower. I believe the newer HK416A5 lowers look more like the traditional milspec lower.

I remember reading that if you are running PMags in a Scar 16, it should be the E-Mags

Nah, BFV's problem with the MR556 was that they converted it to full auto and burnt out the barrel in 10,000 rounds. Which isn't horribly surprising since the barrel was setup for accuracy and wasn't chromed.

https://www.ar15.com/forums/t_3_118/677135_High_round_count_AR_M4_s__over_100_000_rounds__and_how_they_have_handled_on_our_range.html

We no longer use ANY piston conversions or factory pistons guns with the exception of the HK-416 "knock-off" TDI upper. I purchased a FACTORY brand-new MR556 and it started keyholing after only 10,000 rounds. I was SO pissed because I spent all that money on the gun and it couldn't last 10,000 rounds. I had barrels from before we even opened the range with 1,000's of rounds on them from J&T Distributing (chrome-lined) that didn't keyhole well into the 80,000-100,000 range. I don't know who makes or made the J&T barrels but I was so pissed that actually wasted the money on a MR556 and that's all I got from it. I purchased two of the 14.5" TDI knock-offs approximately 6-8 weeks ago and they have been on the line daily with ZERO issues. I only purchased them because people will come in specifically request the "416" and even they've never handled a weapon their entire lives, they KNOW that the top half isn't the "416 like in COD/MW".

The MR556 was intended for Joe Shooter, not for 25 round full auto mag dumps at a high volume range. BFV cares that rounds don't keyhole at 15 yards, Joe Shooter is more concerned about decent groups at 100 yards.



Start at 3:40. It's about a minute or two of discussion.

I wouldn't go as far as to say that. Their primary goal is to have guns that dump rounds downrange and don't keyhole within that relatively short distance. They're not concerned with accuracy as long as the upper keeps on firing

Id love to know how the HK USP stack up against the Glock 17s.

No, I've had SCARs for years, the E-mags required modification same as the Gen 2 Pmags.

Very few people know this, but you really shouldn't run Gen 2 Pmags at all. Because even after you make the mods, the Gen 2 Pmags present the bolt a different geometry than GI mags. They still work but the tip of the bullet may be deformed in the process.

Gen 3 Pmags are GTG, but the aluminum or steel GI mags work best. With that said, I've been very happy with the newest 10 round Lancer Mags.
