Zhur,Zhurdan said:The AR system is gas operated, the PS90 is blowback.
The reason shortening an AR causes some issues, is because the timing on the gas operation is different than with longer barrels. Since there is no gas tube or timing issues concerning the blowback and ejection process on the PS90, there shouldn't be any difference. At least I hope not, because I've got about 2-3 more weeks until I get my paperwork back to SBR my PS90.
lol, no no no. Here is what you do.Zhurdan said:haha... nice. Once I slap the Gemtech on it, they'll think I'm crazy and call the police, so I'll have the range all to myself! MUAHAHAHAAAA.
:-D :-D :-D i've only shot ss195 out of my SBR'd PS90. however it was during a slow period at the range so i experienced no such problems. :? :?Zhur,
I have found a SERIOUS problem with the SBR of the PS-90 when I completed mine. I wished I knew you were going SBR and I would have warned you beforehand. The problem seems to transcend ALL types of ammo, even reloads and dummy training rounds. You become a serious distraction for other shooters at the range. The jealousy and covetousness are almost unbearable.
Keep in mind that the 5.7x28 round was meant for a P90 10.3" barrel, not the 16" civilian legal length. The rifle and the pistol were both designed around the cartridge, not the other way around. So actually, although you may have a little more range and FPS out of the longer civilian legal barrel, you will get more of the intended performance of the 5.7x28 round (theoretically) out of a SBR.I was wondering if there where any reliability/feeding issues with a PS-90 SBR using the available civilian ammo. Do either SS197 or 195 have any know issues being feed / ejecting from a SBR?
