Can I fit this 6.8 SPC upper on any AR15 (platform) lower?
Juan C on Jun 17, 2019
BEST ANSWER: Yes, it will fit on a standar AR-15 Lower. You will need to use 6.8 magazines though.
Why the 1/11 twist rate? Is it more accurate for all 6.8 bullet weights for this caliber, than the standard 1/10?
Ray S on Jun 18, 2019
BEST ANSWER: The industry really started to move away from 1/10 to 1/11 due to the lower pressures, you can load your rounds hotter. Many 6.8 shooters are handloaders.
My first 6.8 was a 1/10. My new one is a 1/11.
will this upper ship tp the house or to the FFL ?
Fred P on Jun 19, 2019
BEST ANSWER: House . The only part that has to go to FFL is Lower Receiver part with the Serial Number.

Christopher F on Jul 11, 2019

Great product!
Another outstanding product from PSA, it turns your AR -15 into a legitimate deer and hog rifle. With an adjustable gas block to fine tune your choice of ammo into a soft recoiling , easy to stay on target when the pigs are on the run . Mine is sub MOA with easy to find federal 90 grain fusion ammo ( 2850 FPS ). The free float m-lock hand guard is a piece of art , very lightweight. I highly recommend this product , get one while there still in stock.
