Awesome set up. - Adams Arms Standard Picatinny Block Piston Kit

When you look at the cost of a complete BCG, adjustable gas block and gas tube, this is only slightly more expensive and worth absolutely every penny. I will be converting my other ARs over as soon as the cash is free. Also - look up their kits that come with a free handguard - it will save you money. I will be using these on all of my future builds, and the ease of adjusting the gas block for suppressed fire is astonishing. I wonder why anyone would go DI after using one of their systems!
