    5.45x39 SBR questions

    I was considering to cut down my 16in 5.45x 39 to 12.5. or buy a barrel. I was told that 5.45 x 39 SBR do not function well and terribly inaccurate. does any one have one. Thanks

    While I can't answer in relation to an AR platform I can tell you that a 12.5" 5.45x39 out of an AK platform is just as accurate as a 16" gun in my limited experience. I had one built years ago and have had no issues with either function or accuracy.

    Back when 5.45 was dirt cheap I could see the interest, but with prices the way they are now I don't see much reason for a 5.45 AR.

    Ballistic Advantage 10.5" barrel... zeroed at 50 yds can hold about a 2" group using Wolf. Should probably break out some better ammo 1 day just to see...

    Sorry, I responded to my own post. You're right, I haven't seen any 5.45's

    I spent years trying to get one of their bolts and a barrel. It’s like one day they stopped making them.

    This round is awesome in my SAR-2,
    But keyholes in my AR.

    When is the last time you bought a 5.45 barrel, let alone bolt from them?

    If I remember correctly true 5.45 barrels under 16 inches have a different twist rate
