    Standalone barrel that's 4150 or better, HPT and MPI?

    In writing something up for my site, I was struck by the relatively small number of barrels available that are 100% HPT/MPI yet are also available as a standalone part without the upper at least.

    LMT is the obvious first stop in quality barrels, but they only sell them as part of a complete upper these days. Same goes for Noveske.

    Either way, if you deduct the cost of a CMT upper, the barrel alone would be about $385 ($485 complete upper - $100 CMT upper price = $385 barrel).

    CMMG barrels are $250-$300 and they say they are MPI (although I think they're only batch) and no mention of HPT.

    Sabre Defence barrels, while a good quality barrel, are batch HPT/MPI.

    And we all know that BM, RRA, etc. only batch test, if at all, their barrels.

    So is there any option for a standalone barrel that is HPT and MPI?

    MSTN sells LMT barrels they are $300 ea 10.5", 14.5" and 16".

    I bought 10.5" and 14.5" few days ago. I guess they use the LMT uppers for their builds.

    Wow, $300 for an LMT barrel? Does that come with FSB, nut, delta ring, and spring?

    Strangely, that would make an LMT complete upper less barrel $185?

    The barrels came with FSB and barrel nut. I bought them as spare barrels for my 10.5 and 14.5" LMT uppers. I like to stock up on parts.

    I was trying to do the same thing Rob buy quality chrome lined barrel but I didn't want to spend the $$ for LMT uppers since I already had few of them so this was the best route to take.

    I think the LMT upper receivers sell in the neighborhood of $150 the remaining $35 would cover the gas tube, delta ring and spring.

    Let's first talk about how many barrel makers are making barrels that follow the .Gov spec (MIL-B-11595E). Here is the short list:

    Sabre Defense
    BCM
    LMT
    Colt
    Noveske N4


    Companies that use vanilla 4150:

    BM
    CD
    ADS
    DD

    Of the companies use the mil-spec 4150, only the following ones HPT/MPI every barrel:

    BCM
    LMT
    Colt
    Noveske N4

    Now of these, which ones will sell stripped barrels? There is only one:

    BCM

    Just as an FYI, $300 for an LMT barrel (with a FSB) is not a good deal. MSTN is basically getting what he paid for the ENTIRE LMT upper by just sell the barrel and then turning around and making another $100-$200 off the upper.

    Check with Denny but I think his Operator barrels meet all of your specifications. Supply though sometimes is an issue.

    The OPERATOR is a Dennys Guns/GTS exclusive.

    THIS PACKAGE INCLUDES THE BARREL AND GAS TUBE AND DELTA RING ASSEMBLY

    The barrel is a 16.1 INCH Mid Length gas. The blanks are Rockcreek(Mike Rock). The barrel steel is 4150 Chrome Vanadium, full auto rated.

    These barrels are fully chrome lined, bore and chamber by US Chrome, who does Colt and most other top line tier one manufacturers barrels

    1:7 twist.

    MP tested.

    Proprietary profile, mid weight with a slight taper from chamber to the gas block.

    Weight of barrel: 2.5 Lbs approx.

    M4 barrel extensions.

    F front sight, pinned.

    5.56 NATO chamber.

    Barrels will be parked under the front sight base.

    Threaded 1/2X28(standard M16 thread) A2 flash hider included.

    Standard barrel nut will be installed. Delta assembly will not be included as many of you will be using rail systems and I dont want to add $$$ for parts you might not use. They are available as an option. Same with the Middy gas tube.

    Call and ask Denny.

    I emailed Mike Rock and he replied he just supplied Denny with blanks, and Denny does the rest. He's not sure if Denny HPT's them and/or if every barrel is tested or just batch tested.

    Don't call though unless you've got some spare time on your hands. Denny's a talker......
