9mm 'Stinger Series' PDW Assembled Uppers

The 22Mods4All SA9 'Stinger PDW' Series Complete 9mm Upper Receiver is built from the ground up to provide outstanding reliability and accuracy with a host of top tier features. The SA9 'Stinger PDW' combines the popular performance and low cost of the 9mm round with the compact, high quality reliability of the short nitride barrel only the popular Bear Creek Arsenal can provide. Lastly, the slim-line Handguard, built by Daytona Tactical, is ultra-lightweight, free-floating with a monolithic top-rail. This handguard comes built from heavy-duty T6 aluminum and is compatible for your favorite accessories. All of our 9mm uppers use a blow-back gas system removing the need for traditional gas systems. The Anderson Manufacturing upper receiver for this 9mm upper is slick-sided unique to this pistol caliber. Bolt and Upper is fully cut and compatible with Last Round Bolt Hold Open (LRBHO) technology that allows for reliable bolt lock back when combined with a Glock magazine compatible lower.

There's a set of optional check boxes right under the description for adding a charging handle and BCG for $119 and or a magwell block adaptor for using standard lowers for $90.

What? Who wrote this description.... T6 aluminum, slick side upper unique to the pistol caliber... since when, and what 9mm upper doesn't use a blow back gas system? Why not skip the meaningless jargon and give me some actual info, like does the upper come with a bolt and charging handle?

I think you have a couple of things confused. Practically all affordable pistol caliber AR pattern rifles/pistol use direct blow back INSTEAD of a traditional AR gas system. (CMMG has a radial delayed blow back line, and SIG's MPX uses a fully closed and rotating bolt and piston gas system. Both of these options are a little spendy.)

Some pistol caliber uppers have a downsized ejection port since the 9mm/.40/.45/10mm have shorter cases than 5.56/.223. And many pistol caliber BCG don't have forward assist serrations, so a lot of pistol caliber uppers are "slick side" meaning they cannot accept a forward assist. (Personally, I prefer to forego the forward assist on all of my AR uppers regardless of caliber, but YMMV.)
