So if I have a 16" .450 AR upper that is functioning properly and ejecting at about 4 o'clock with a standard carbine and buffer spring....Is there a combination of buffer (H3?) and extra power spring that is likely to cycle a standard supersonic round without an adjustable gas block through a suppressor?
I can't seem to find the answer. My buddy is trying to accomplish this on his .308 and got me thinking if someone here has done it on a .450. I assumed I would need adjustable gas. However quickly switching back and forth is not that important to me.
Thanks
