  1. Do any pistol mag adapters for a standard lower work with a rdb upper? I would think it shouldn’t be too hard to make one that works, considering you’ve already got the geometry figured out for your proprietary lowers.

  2. Here's a question. Has everybody read this?
    We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.–That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, –That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

  3. My CMMG Banshee 22lr SBR…. It comes with a buffer and spring even if it is not needed for the 22LR. What setup is that designed for? Will it function with the 5.56 upper or 300 blackout upper with no change to the buffer weights? What weight do those short buffers come in? I do not see any options for different weight and they are shorter thank normal, about 2.25" long. Is that the same buffer as in the Banshee 300 gun be it 300BO or 5.56?

  4. You need 6.8 SPC. And my Banshee 300 in 7.62×39 is still on backorder after almost 9 months. I ordered it from The Silencer Shop. When I ask them I’m told “we’re waiting on the distributor to get them and have no idea when the order will be filled” and when I ask CMMG I’m told “we have no idea, you need to ask the Silencer Shop”. So I’m in the middle with an already paid for gun.

  5. Following up on the first question re: 9mm/5.56 using standard AR lower and conversion mags, would you consider developing/making conversion mags for 10mm/10mm mag from .224 valkyrie/6.8 SPC mags? They have the same parent case and you could play the same trick with the 10mm upper and .224/6.8 SPC upper on a standard AR lower.
