    LWRC 10.5, or LMT 10.5 upper?

    I have recently been blessed with the opportunity to buy a 10.5" upper. From those with experience, which one would you pick? LWRC 10.5 or LMT 10.5 DI? I am currently running a H3 buffer and Wolff Extra Power Spring in my 14.5 SBR. Thanks for the input.

    I have a 10.5 LMT with the Fa bcg, h buffer,and factory spring. I have shot .223 rem,pmc bronze, and fed xm193 with no issues what so ever.

    I have had great luck with my LWRC. I know a lot of folks hate on them, but they build a nice rifle.

    That said, I'd be tempted to go with the MRP. You can get the 10.5 in barrel like you said, or swap it out for the 12.5 piston, or even go with a 9mm barrel some guys are selling.

    You'll win either way IMO, but I think the LMT would be a more versatile choice.

    My old no-name DI would have some issues after some FA suppressed fire.

    I love my 10.5 LWRC - runs like a top. had issues a couple years ago with the equivalent of the gas tube coming loose and bending under the piston(wasnt staked) - LWRC took care of me. Looking to eventually retrofit with the new one piece carrier.

    Honestly this rocks with FA and suppressed - Mine normally wears a AAC M4-2000 - and a true RDIAS. This is really where a piston shines IMHO.

    I'll admit that I've never been a big fan of LWRC because of their history but I fondled one of their SBR guns at Virginia Arms and I was impressed by what I saw. Of course I didn't get to fire it but it certainly looked nice.

    I'd say you couldn't go wrong with either. I saw go with the LMT for cost but if you plan on running a suppressor then get the LWRC.

    I've own/owned the following

    LWRC M6A1 10.5" upper
    LMT MK18-ish 10.5" upper
    LMT MRP 12.5" piston upper

    If I had to choose one, it would be the MRP. Why?

    MRP gives you a true monolithic upper
    MRP has can be direct gas AND piston

    The MRP gives up nothing to LWRC and the MK18. If the MRP is not an option, because you just dont want it, I think I would go with the LWRC because SBR suppressed weapons are great with pistons.

    I have an early 10.5 inch LMT that I've run almost exclusively on fullauto with a conservative guestimate of about 5k rounds. Much of this has been suppressed. The only failures I've experienced are several failures to feed, which occurred after about 300 rounds of suppressed fullauto fire. The action was absolutely filthy, had not been re-lubed and the bolt carrier was just dragging through all this filth. Applying some lube immediately solved the problem. In my estimation, these FTFs were due to loss of bolt velocity on the return stroke due to bolt carrier drag in the setting of excessive fouling/debris within the upper receiver and on the bolt group. When shooting unsuppressed, I have never had a failure in this upper.

    I have a Noveske N4 hammer forged 10.5 inch upper that I have yet to shoot. It is waiting for me to install a Daniel Defense Mk18 RIS-2 rail.

    Just out of curiosity, have you considered buying a BCM upper with hammer forged barrel? This would be my preference at this point, however I have no experience with their short barrels. Knowing BCM, I would venture to say that they work as advertised. They also offer uppers with 11.5 and 12.5 inch, as well as in lightweight configuration.

    I have an LMT 10.5" that has been 100% reliable, the most rounds through it were a couple of thousand with out cleaning and about 1,500 at a Magpul Dynamics class without adding more than 3 drops of oil to the BCG.

    It is very accurate and has turned out true sub MOA groups at 100 yards.

    If I was buying another shorty I would buy another LMT or a Bravo Company.

    Thank you to all who chimed in on this. I was able to get a brand new M6A2 upper for under $1200. I couldn't be happier with it. With the H3 buffer and Wolff Extra Power buffer spring, it lobs brass out to about 3' away at 3 o'clock. The recoil is minimal with this setup, including the BattleComp. Thanks again to everybody's advice.
