The long stroke design is used in AK series (47, 74, 103) and AR series rifles. Long sttoke is the most popular type of rifles due to its efficient design and lesser moving parts. It is obvious that most guns share similaity as the technology ia not too complex and hence almost everyone who designs a gun will design in certain fixed manner.
Making a gun is not a big accomplishment. I was just replying to your absurd comment.
Wow, AR series are "NOT" longstroke piston driven guns but DI guns, in other words it has no piston, , AR conversions to piston are short stroke pisons like the G36, HK416 series, and then there are roller delayed actions too in prolific platforms like G3's. In fact you couldn't be more wrong that long stroke has lesser moving parts, because direct impingement literally have no piston in them.
Lastly making as gun is not a big big accomplishment, sure you are absolutely right, I have put together ar15 and ar10 in my garage, but designing a gun from scratch can be challenging, given that OFB's bootleg designs miserably fail at trails and the fact they have never really designed one single rifle system in thier 218 years of existence should make it a big "accomplishment" for OFB.
Anyone with a shred of common sense will tell you that Insas is a copy of the AK platform, and that too not done well. Because there is another rifle based on the Ak platform, but developed correctly: i.e. galil, and today IA is going to look at galil as contender to replace Insas on their Israeli junket, what a travesty.
