New Products For 2015 From DSA: Infantry Automatic Rifle And More

DSC007272

DS Arms, the Illinois-based company known for their high-quality FALs, had a few AR-15-centered products to show off this year at the SHOT Show. First, they had the second version of their AR-15 armorer’s tomohawk, the Z-Hawk:

Beyond that, they were showing off their new Bufferloc AR-15 modification, an inexpensive drop-in system for preventing carrier tilt and adding more mass to the moving parts group:

As an aesthetic option to go with Magpul’s new MOE line of handguards, DSA also had featured its new delta-ring design:

Most interestingly, though, they also had two IARs, a 16″ prototype and a 11″ developmental model:

The IARs both featured aluminum heat sinks: Machined on the prototype and cast on the 11″ carbine:

DSA is targeting the international market with this rifle.

    I think quite a few manufacturers have already beat them to the IAR concept.

    Basically this is nothing but a short stroke piston m4….which many companies ha ve done already, although the Marine Corps have adopted it.

    • It is DI, I am pretty sure. Also, the M27 does not have a separate heat sink, though the Colt IAR does.

  • Ergo

    i really wish they had released that buffer loc a few years ago when i was interested in pistons.

    I’m quite sure that heat sink is effective (think of the construction of an aluminium
    household radiator),
    but how do they solve the problem of the heat expansion of the barrel?
    Well, I guess it can’t be that significant, since gas blocks are also attached in the same manner.

    Probably impractical but I don’t care I am going to say it anyway.

    It would be cool if they made a 5.56 FAL or worked a contract with IMBEL of Brazil to bring them in. 922r would be easy to accomplish especially when parts are already out there for the FAL and AR mags are all U.S. made anyway.
