I want reliable, accurate guns. That being said, I don’t see the need for the ‘space’ guns anymore. I shoot mostly Multi-Gun and 3 Gun games with a stock XCR. It was an MOA gun right out of the box. I decided to join my provincial rifle association to get some trigger time at longer ranges (USPSA Nat. have LaRue’s!) so I had to get a ‘service’ rifle. I bought a STAG and it shoots sub MOA out of the box. What limits me from shooting all possibles is me & the dang wind, not the rifle. It is just a service rifle, no free float tube no special parts, (I did install a match trigger but don’t notice any difference in group sizes). I think all the top end .223/5.56 rifles are capable of this level of accuracy now out of the box. My new standard issue STAG will out shoot my old Mossberg small bore rifle at the 50m mound; now that is saying something about the modern AR’s.
I’d buy a ‘space gun’ if it had an advantage but I don’t see the need. 10 years ago, yes, nowadays, no. 10 years ago you couldn’t get a reliable .45 either without spending lots on custom stuff; that is far from the truth today. It has been my experience that modern guns are more capable the vast majority of the people using them.
