  1. Must Have for the M249

    Posted by Alexande on 7th Mar 2017

    If you have a M249 then you need this brass catcher. It works great with my M249S. No longer do you have to chase down m27 links after shooting. The installation kit makes drilling the handguard a breeze and relatively stress free. Highly recommended.

  2. New Product

    Posted by Unknown on 4th Nov 2016

    I got the opportunity to be one of the first with to own this product. The quality is first rate and the design is very solid. TBR isn't the lowest cost brass catcher out there, but I'm willing to pay for quality if there is a difference. I've tried other alternatives and there is nothing like TBR. I love the way the M249 system is set up. It's every bit as solid as my m16 system I bought. I have lots of full auto firearms and it's a challenge to make these brass catchers work 100% reliably with FA firearms, but TBR has done it and done it very well. Also customer service is top notch.
    I recommend their products to all my friends and customers.

  3. More Tactical Brass Quality

    Posted by Craig on 3rd Nov 2016

    I already have SCAR 17 and M-16 brass catchers so I had high expectations of the M249 product. Didn't let me down, good engineering, quality construction and the measuring template for the older non-all-rail forend was great (even when I put it on the wrong side...can't stupid proof everything). Is it expensive? Well, look what it goes on...Quality isn't expensive, cheap is.
