Yes it's a non-shouldered barrel and was run with a barrel nut. Appx 4-4.5 lbs. I ran less than 40 rounds down the barrel so the velocity I had is really insignificant. But I ran both and H4350 and RL26 about 20 rounds each. RL-26, 48 grains, 2992 fps, H4350 was in the 2850 area. This is a standard light Palma barrel.
