    10.5" Mad Dog Weapons System 300 Blackout AR bbl

    9" Primary Arms AR hand guard



    PM


    $75 for barrel, includes AR Performance muzzle comp/flash hider

    $75 for hand guard, includes Midwest Industries key mod covers



    Bbl marked "300 AAC BLACKOUT (8)". Uses pistol length gas tube. .750" diameter at gas block position. 5/8x24 threaded. 1 in 8" twist will be fine for bullets 220gr and lower. If you will be shooting pointed 240gr bullets, a 1 in 7 twist would be more appropriate. Marks in bbl finish from sliding the gas block in place. Previous owner said fired max of 200 rounds; examination of the bore shows no sign of wear. Gaging the throat showed the rifling read as-new. Will need a washer in order to index the comp/flash hider in place.

    9" key mod hand guard marked PA. Was told it was made as a special run by Seekins for PA. Includes the bbl nut and screws and shims for indexing to the upper receiver. Shim set not shown in photo. Inside diameter is 1.88" so the typical 1.5"-1.56" diameter 30 cal suppressor would fit inside if used with a short enough bbl for those that like some of the suppressor inside the hand guard. Couple of tiny marks on the edge from use.


    I bought the above bbl and hand guard in a smoking deal for $150 shipped from a guy changing calibers in his SBR. Figured (hoped) someone local could use them if I didn't. I'm selling them for what they cost me (but I am keeping the gas block for a new upper that just started coming together this afternoon). Also, I just got an email from Max, the COO of Primary Arms. When PA had the hand guards made and for sale, the price was $160. Any questions, just ask. More pics, just ask.

    Time to bump in case someone is looking to build a short bbl 300 Blackout upper.

    A weekly bump. Perfect for someone building an AR Blackout pistol or SBR upper.

    Weekly bump. Maybe I was wrong and nobody wants either of these parts...let's see.
