    ACR 50 Beowulf Conversion

    I've been trying to find someone to manufacture a conversion kit to make my ACR run 50 Beowulf. No luck thus far. Does anyone have a helpful tip, or can anyone point me in a good direction?

    There are definitely folks here that can do it. Biggest obstacle is someone has to custom make a one-off ACR gas block for the larger journal for the beowulf gas block. Think the diameter is .906".
    I'd love to see what someone comes up with.

    Bolt could be modified to work. Barrels are available. Gas block and op rod support block would need to be custom made.

    I think Nefarious Arms made their own gas blocks, and Templar Precision's .300blk gas block looks like their own design as well. I'm sure it can be done but for a one off kit IMHO the cost would probably not be worth it. I'd rather just grab a .450 BM conversion since it has better ballistics than either .458 SOCOM or .50 Beowulf.

    Hopefully now that BM is making a .450 factory ACR they will start selling the conversion kit soon.

    I’ve though about this for a long time. I will eventually do a 458

    I make my own gas blocks using Remingtons dimensions. I will be doing other variants outside of 300blk eventually soon. The lowers are my main goal once I clear this current side job up.

    With that being said I already have the design for a dedicated unsuppressed setup done. I just have to make them up. The barrel is already here as well. It’s not a Beowulf but I can change some stuff to do a similar setup.

    I think I've thrown my hat into the ring here on this issue before. Count me in on 50 Beowulf.
