I got an email this morning from Guy Tal over at MagLULA announcing their newest Israeli-made product, the 30-round AR15 / M4 universal heavy-duty Range BenchLoader. It appears to be a polymer cost-reduced version of their existing AR15 / M16 / M4 BenchLoader. Given that this new version has a MSRP of $165 (versus $430 street for the older one), I think it has much more of a chance at succeeding in the market. You can see how it works in this video.
Personally, I’ve always been a little skeptical of the need for this product for individuals – I find that the stripLULA works wonderfully if you get your stripper clip infrastructure in place ahead of time. I would have a lot more use for a cost-reduced variant for AK and/or Galil mags, since neither of those can use stripper clips effectively. (And where is the AK-74 stripLULA?)
