I don't see the attraction of putting one of these uppers on an AR lower. The big thing here is no need for a buffer tube. You can have a folder. AR lowers use buffer tubes. I guess you could screw in some plug with a Pic rail on it to attach a folder, but why go out of your way to go Rube Goldberg? |

I think those goofy rear side fins are somehow related to the upper being significantly wider than a normal AR upper?

Yeah, I think you might be right. Maybe they (or someone) can come up with a cleaner end cap for the upper that’d mate up to a lower like the Brownell’s 180. https://www.AR15.Com/media/mediaFiles/53338/515522F7-4D9E-4956-A412-DFAAE73CC04E_jpe-1252194.JPG View Quote ![]() |

Quoted: And to expand on this, the majority of the AR aftermarket would only be beneficial to the lower even if they had made their own proprietary lower that could utilize AR parts. Rails/handguards? Monolithic upper, no need. Adjustable gas block? Already have one. Barrel? Sounds like it won't be easily user serviceable like an AR so probably no drop in barrels. Charging handle? Different from an AR so will require its own aftermarket. Bolt and recoil system? Probably going to be unique to this system. So now that pretty much leaves all the stuff you can do with a lower like stocks/braces, grips, triggers, etc. It's far easier and more logical to just use a pic rail adapter for an AR than design and tool for a proprietary lower that either has all of it's own stuff or that would work with all of the AR stuff.

Different view with receiver open at 0:50 ![]() eta: at 2:35 he makes it sound like the adapter fins are mostly cosmetic Random thoughts: 1.) Looking at the tail of the bolt carrier, it didn’t look rdias compatible as-is, but I’m not gonna give up on that one yet. 2.) I’m with the designer on the left side charging. I’d rather have his upper with just left side charge (just my choice). The geometry looked slick with hitting the bolt hold open while retracting. 3.) I’ve never been much of a piston fan, but this gun is really drawing me in for some reason. If the Wolf steel cased 300blk shows up cheap and plentiful, I might have to even buy my first 300. I’ve resisted all these years (being a Grendel guy instead), but this just looks too slick to pass up if it ends up being a decent product. Quoted:

It's a long stroke ACR, or an XCR with a Stoner bolt instead of the AK system, or a Faxon arak-21. They took the front of the B&T apc and switched the locations of the vents and mlok slots.
That price point is going to hurt the competition, which doesn't bother me at all. That guy has my dream job. |

Not sure how the JAKL upper is configured internally, but the increased height is obvious from the above photos/videos. |

he also mentioned in one of those videos that they are currently at 5lbs 10oz-6lbs right now, but he hopes to be able to knock a few oz off in the final version. Also the barrels are not swappable, etc. More or less designed to be permanently installed.
And they intend to do a 9mm blowback version that uses a lower that takes scorpion mags. That would be cool, too. |

Aside from thew "wings", it's pretty similar in concept to the MCX adapter plate: https://www.sigsauer.com/store/media/catalog/product/cache/1/image/1800x/040ec09b1e35df139433887a97daa66f/2/4/2401191-r-2_1.jpg https://op1.0ps.us/365-240-ffffff/opplanet-sig-sauer-mcx-stock-adapter-kit-2401191-r-main.jpg View Quote View All Quotes View All Quotes Quoted:

The unswappable barrel kind of concerns me. I probably won't ever shoot it out but still... that's weird.

Quoted:
It strengthens the weakest point of the lower by passing any off-axis side-side force to the upper rather than the most delicate part of the aluminum lower. That is a very smart and forward-thinking feature. View Quote He made a comment about it "being the new thousand-yard gun." Tightening the movement between all axis between the upper and lower may be part of their attempt to put some truth in that statement. Regardless, that non-reciprocating forward mounted side charger pretty much sells me on that upper. |

Unless the upper's primary structure is actually polymer (which it isn't to my knowledge) the barrel will be swappable.

He said not designed to be swappable. He said you'll break the screws trying to get them out due to the way they are installed and the thread locker they use. Obviously you can "get them out", swap the barrel/remove for barrel work, etc and then get new screws (maybe from PSA directly?) But it won't be a straightforward job that guys can do at the kitchen table or in their garage like most guns of this type (mcx, scar, AR, etc).

This thing is shaping up to be what the. ACR should have been. I'm both happy and disappointed.

I wish the uppers were going to be released first so I could slap it on my SBR lower, but I suppose buying a whole gun is ok at that price. Another lower certainly isn't going to be a bad thing to have around. I've only got 12.....

Wonder how you'd ever get an acr stock on an AR lower. That would be sick on this thing.

Looks like there will finally be a true budget monolithic extruded aluminum rifle ala CZ Bren, SCAR, ACR, XCR, APC, and the HK433. This seems to be the future of fighting rifles post Di AR15s.

AFAIK, you probably could do this route but it appears PSA is creating their own AR-15 buffer tube thread to 1913 rail adapter for the JACKL so that the "lines" of the firearm don't look all jacked up.

I’d really like to use a Shockwave (Gen 2) Blade that can fold.
Any recommendations on an inexpensive (yet decent quality) folding stock adapter? |
