Thanks for joining the discussion. With respect, that's not a spec list. It's an accessory list. What can you tell us about your bolt carrier group, barrel chambering, gas system length, gas port size, gas block material, gas block attachment method, etc? How does the rail / barrel nut interface work? And finally, in a world dominated by keymod & mlok, why did you choose to use a proprietary attachment system on the rail?The weight with a Roger's Superstock is 6.43 lbs.
Here is a link to the page and a spec sheet for the Prestige Series:
