BCHunter, the lower they used for 25 rounds of succesful test fire was their standard Carbine Mil Spec Lower, should be identical to what I have as M and P 15 lower.
I did ask about what Mags they used and they said it was standard 30 round pmag used for 223/556 and they loaded 10 rounds of Hornady 123 grain black in it. I found that interesting that they did not use a mag designed for 6.5 grendel round like elander.
My upper is currently with a gunsmith trying to figure out buffer spring weights. If he cannot figure it out then I think I m going to ask PSA to drill the gas port to make larger like some folks have mentioned in the message board here.
