Thanks for posting. I want a middy and to my understanding, the CQB MRP is the ONLY middy LMT makes. Since LMT is on my short list of ARs to look at, naturally, this is the model I gravitate towards when looking at LMTs. I'm glad to see that the author reports good MOA from the LMT. I spoke with a dealer a few days ago that told me that LMTs are battle rifles but have horrible accuracy. He said an LMT dealer promised a customer of his a certain MOA w/LMT and after hundreds of rounds, the customer couldn't achieve the results he was promised. He then told me that this same customer returned the LMTs for a refund and then bought a Noveske from him. Supposedly, the customer achieves outstanding results and has since then bought multiple Noveskes from him.

I'll have to go back and read the article about traditional and direct impingement systems.

The LMT MRP comes in two lengths, CQB and Rifle, both of which will accept the 16" mid length barrel. Keep in mind, these barrels are heavier than standard profile though. There's also a new lightweight chassis available, but I have no experience with it. I had a 12" piston MRP a while back.

Huldra Arms - Ultimate Gas Piston Rifles

Huldra's accessory page took me to Tapco and UTG. That bothers me. Any rifle manufacturer using these types of components says that they're target market are not professionals.

Here's a review I did of the Huldra Arms system.

I can say for sure that Dave from Huldra really knows his stuff.

I have no reason to doubt that they build a decent rifle or that they know what they're doing. But, the fact that they offer those types of accessories bothers me and makes me question who they're marketing to.

Also, there are a couple piston rifles/uppers that are basically the go-to for a fighting piston AR that I don't see changing until there's a TDP for piston rifles.

Another thing.. A lot of Huldra's claims aren't going over so well on m4carbine. they claim that DI is a thing of the past and their system is superior. When question, they do no HPT/MPI testing on their barrels or bolts and they couldn't even answer what grade of steel they use in their bolts, though they said stainless. Why they wouldn't use Carpenter 158 is beside me. My only guess is cost savings as their choice is not superior.

They made claims about how a DI M4 will fail early without cleaning or lube, but that has been proven wrong so many times. There are countless tests out there by well respected people in the industry running DI rifles beyond 8 basic ammo loads without cleaning and in some cases, without adding lube.

It seems like a lot of what they say is not based on fact, but pure marketing. They made claims about abusive tests, but when asked about the tests they failed to answer with specifics. I've never once seen any of this from BCM, Daniel Defense, FN, Colt with their new piston M4 or HK with their piston line.

It goes on and on, so I'll just link to it. Right now, they remind me of Spikes, but in the piston world. When people may put their lives on the line with one of these rifles, there is absolutely zero room for exaggerated claims or false testing.

If I were to buy another piston AR, I'd go with the 416 (not the MR556 version) which I have some time on or another LMT MRP. My 8" LWRC has been fine, but the company has changed hands and gone through too many changes for me to trust them right now. I wouldn't turn one down at the right price though.

I have no experience with the Sig, but have some time on the PWS 7.5" rifles in 5.56 and 7.62x39. Surprisingly soft shooting and very reliable, which was also surprising. One day we put about 880 rounds through the 5.56 on a full auto lower and not one failure. I have no experience with their other rifles.

I'm not trying to bash Huldra here… I'm just pointing out what I've seen so anyone reading this can see what's out there. The link to m4carbine contains a number of posts from Huldra Arms answering questions.

One note: The article only reviewed the Ruger SR556CLA. That rifle does indeed have the flash hider machined right onto the end of the barrel. The standard Ruger SR556FB model has a threaded barrel and the flash hider is removable and interchangeable with many other products. the FB model also comes with a quad rail system instead of just top and bottom rails. (It is just little bit heavier though). My FB model stays amazingly clean after a day of shooting.

Let me give you a perfect example of what Jon is talking about. Take a look at Rainer Arm's and you will see the difference in the types of products and brands they carry. They are local up here and have made quite a name for themselves in quality AR's.
