    Which 6mm for 18" barrel?

    I like the new 6mm Max the best in an AR15 platform.

    Where is 6arc going?

    I believe the future of the 6mm ARC would really take off if and when the U.S. military would ever adopt it across all branches of our armed forces and just not special op units. From CQB SBR's to 1,000+ yds along range rifles, the 6mm ARC checks a lot of boxes, in an AR15 sized and weight rifle...

    New tech and advancements are here. Whats the new best AR15 cartridge?

    Geissele should have their 6mm ARC rifles out in the next 1-2 months. They are using a barrel extension and mags that are specifically made for the 6mm ARC cartridge. It will be interesting to see how the new 6mm ARC shakes out in the AR15 platform in the next 1-2 years. www.gunsandammo.com ›...

    New tech and advancements are here. Whats the new best AR15 cartridge?

    The best overall cartridge for civilians, police or military ? For a new military cartridge out of 12.5" barrels to 20" barrels, for CQB out to around 1000 yds, **maybe** the new 6mm ARC. It checks a lot of boxes.

    New tech and advancements are here. Whats the new best AR15 cartridge?

    6mm ARC vs 5.56 / .223 0-300-500 yds (12.5" inch -18-20" barrels) = 5.56/ .223 (30rd mags) = Okay 0- 600 - 800 yds+ ? ( 12.5" inch - 18-20" barrels) = 6mm ARC (25 rd mags) - Better penetration through barriers ? = *Overall* better ?? How does barrel life compare between the two ?

    Advice on QD mount for Vortex Razor 1-10

    Personally, I would get a Reptilia Corp ( they will be also coming out with 1.700" and 1.930" height mounts in around 6 months), Badger Ordnance, Geissele, Spuhr, Nightforce Unimount or Scalarworks mount and run a 12:00 or offset closed emitter red dot or run offset iron sights. You could use...

    Ballistic advantage 18 inch fluted SPR barrel

    IMHO, getting a good Ballistic Advantage barrel (one that really shoots good) is just too hit or miss *for me* to mess with.

    1 in 9 twist 20 inch Hbar and 77 gr bullets.

    IMHO and in barrel makers opinions, 77gr or above = 1 in 7 or 1 in 7.7 twist is best and 1 in 8 twist depending on the barrel length can be good to very good.

    Geissele GFR 6 ARC or Cobalt Kinetics SPR Elite in 6mm ARC

    Two unique features of the Geissele rifle are, it uses a reinforced upper receiver and also a 6mm ARC specific barrel extension for better feeding with no bullet tip damage. Their mags are also designed and tweaked for the 6mm ARC cartridge.

    New 6mm Advanced Rifle Cartridge

    I received my Geissele 6mm ARC 15 and 25rd mags today from Brownells. They fit perfectly in both my AR15 lowers. Mag release worked fine, the bolt locked back on them and the bolt release worked fine. I have nothing to compare them to, but the fit and finish looked fine. The follower worked very...

    Is 14.5 too short for a DMR?

    Out past 450-500yds I will take a 6mm ARC AR with a 18" medium profile barrel and variable optic to match. IMHO, the 6mm ARC checks the most boxes, barrel life at around 52,000 psi being just one of them. I really think it is the future and time will tell.

    New 6mm Advanced Rifle Cartridge

    Just got off the phone with a guy at Geissele. He told me that they designed the 6mm ARC mags to their specs and are currently manufacturing their own mags (6mm ARC specific mag bodies and followers) **in house** right now. He also said, *at this time* they have have no plans to offer just 6mm...
