    20" Barrels

    What's going on with all the 20" barrels, they all seem to be drying up.

    While I prefer to use a BCM 20 inch barrel with 1 /7 twist, F marked front sight base and M4 feed ramps, their barrels have been sold out for some time. CMMG seems to no longer have them on their web site and Bushmaster's 20" government profile barrel with no 1/7 twist + no M4 feed ramps + no F marked front sight base = I'm not buying it for my A4 build.

    What's going on here?

    Nobody buys them, so they aren't a high priority on anybody's list.

    Check PSA's website. They make a 20'' Upper with an FN barrel.

    Thanks, well I found what seem's to be their brand in the link below, I wonder how good the quality is, but looks like that's all that one can choose from that's close to spec, other then BCM.

    I've been looking for a proper govt. profiles 20" barrel/upper with RIFLE feed ramps for some time now, but no one seems to make them.

    Weird. I've never seen them without rifle feed ramps.

    Where have you found Mil Spec barrels with M4 ramps?

    IIRC some guys here were using, if not considering this brand for A1 and A2 builds.

    I have no personal experience with them but Ive read theyre ok.
    Here's an old thread on them.

    Might be worth emailing them for the complete specs.
    ETA: I clicked the photo and they appear to have M4 feedramps. I dont know if the photo is accurate though.

    Got one of these barrels a few months back and I love it. Half inch groups at 100 yards.

    Midway has AR Stoner 20 inch govt. profile chrome lined 1x7 twist 5.56 barrels in stock here:

    http://www.midwayusa.com/product/154...me-lined-matte

    I believe the AR Stoner barrels are manufactured by ER Shaw for Midway. The barrels seem to get pretty good user feedback reviews. I have a 20 inch HB in 6x45. Seems pretty good so far but with under 200 rounds through it Im still breaking in the barrel. The specs on their AR barrels look pretty good.

    Wow. Real FNMI surplus barrels were a piece of cake to pick up on the surplus sites not too long ago.
