I did some looking for info on Piston Driven 300 BLK Uppers & I'm not finding anything that makes me want to go that route! A lot of people are saying that it has problems cycling!!
Any thoughts on that? This would be my first Short Barreled AR, First venture with 300 BLK & also first venture with Piston Systems, so any insight would be appreciated!
