Stoner 63 has constant recoil. This is where Jim Sullivan got his inspiration to make the Ultimax 100. Jim Sullivan was also involved with the design of the Stoner 63, since it was derived from the Stoner 62 7.62 NATO weapon system, just like Sullivan scaled down the AR10 to make the AR15 with Robert Fremont at ArmaLite Inc.
The original assault rifle has constant recoil as well. It's one of the most overlooked operating systems in firearms design. We're still in a stagnant era of firearms design, basically plateaued from the late 1950's and early 1960's. This seems to be a common theme across all disciplines. Every half century, a genius innovator comes along and takes the collective work before them, and synthesizes it into something greater than the sum of the parts.
Browning was that way, Schmeisser & Walther certainly advanced design and production efficiency, and Stoner took firearms design and manufacturing into the aerospace-grade materials arena, with some other unique designs for the operating system, multi-lug bolt, DI gas, bakelite & carbon fiber furniture, aircraft aluminum receivers, etc.
Jim Sullivan argues that the AR15 still has residual issues that he has been addressing for a while, to include buffering it to reduce the cyclic rate for FA guns, extending the gas key, elongating the cam pin path (LMT has done this with the enhanced carrier), increasing bolt lug thickness & length, increasing the barrel extension teeth length, installing a hammer-effect in the carrier, etc.
