New P Series Micro Block Piston System from Adams Arms
Adams Arms announced the company is now selling its new P Series Micro Block piston systems for AR style rifles and pistols. These kits are designed to replace the typical direct impingement system common to the AR platform with a short stroke piston.
Adams Arms has been selling piston kits and rifles for a while now, so this is not its first offering. That means the company has a fair amount of experience with these kinds of systems. Here are a few of the features associated with the new kits.
The kits use a P Series Micro Block to siphon gasses from the barrel. The block is 40% lighter than the previous XLP block. The block direct gasses toward the drive rod which in turns operates the patented one piece bolt carrier.
According to the company, the parts have a LifeCoat finish that is corrosive resistant. All of the parts are backed by a lifetime warranty and are made in the United States.
The block can be purchased alone for $138.59. However, I suspect most people will buy the block as part of a full kit. Adams Arms offers kits in four different lengths: rifle, mid, carbine and pistol. All of the sizes are sold for the same price: $274.99.

Im an advocate for superlative arms piston kit.
Bonus: when ordering from their site le/mil get 20% disc when it ships
40% of the weight of a gas block isn't the weight savings I really yearn for. Also, it appears to be at the expense of adjustment. Good for them for coming out with the option, though.
I bought an Osprey kit a few years back and have been entirely unable to get it to fit under any handguards I buy for it. They have a (hopelessly small) list of compatible models but none that I like. So I was looking at getting a Superlative Arms setup since Bill Alexander's business policies never endeared me to his products. After over a month of no response on a question sent through multiple methods to Superlative, which seems to be addressed to a fly-by-night style rental garage location, I'm pretty sure I will actually be going with an Adams Arms piston setup, because of all the available piston kits out right now (the three I've mentioned), this line has been out the longest.
