Been researching piston uppers for years and by far the best ive found is the arak21. Came within a week of ordering. Fits any mil spec ar lower. The adjustable gas block makes this a perfect system for suppressors. The long strong piston also reduces the recoil in comparison to di.

Out of the box, the quality of this upper is exceptional. The milling, finish, design, and function are top shelf. I own many piston uppers and I consider this upper to be the all-around best. I hope my range fire experience is as positive as the unboxing.The only negative comment I have is with the packing of the upper. The Faxon box was twice the length of the upper, with no internal packing material. The upper was wrapped in a plastic bag and was free to slide freely back and forth from end to end during shipping. This caused the barrel assembly to be pushed back into the monolithic upper receiver by approximately an eighth of an inch. Thankfully, I was able to use a wood shim and mallet to knock the barrel back into proper position. This also caused the plastic bore safety to be jammed into the bore of the barrel needing plyers to remove it. Upon inspection, thankfully, the upper and barrel were not damaged. I also noticed the muzzle brake was not timed very well and is slightly off center.OP should have noticed the movement of the unsecured upper in the Faxon box when they packed it in the OP shipping box.

A part of me wants to give this 4 stars. Only because it is advertised as having the ability to quickly change barrels. However finding the shorter or 300 BO is not available anywhere currently. That and the "sand" tone doesn't really match the FDE. That being said the long stroke gas system is amazingly simple and very easy to access. You can open the gas system up completely. The muzzle brake is very nice. Reduced recoil and closing the gas made it very easy to make a very tight group.
