Piston vs. DI: Is the Adams Arms AR-15 Upgrade Worth It? (Archive)

In this comprehensive double-feature review, we take a deep dive into two popular products for AR-15 builders. First, we'll look at a classic-style AR pistol built on a Palmetto State Armory (PSA) 10.5" Cold Hammer Forged (CHF) kit. Then, we'll review the Adams Arms P-Series Piston Retrofit Kit that was installed on it.
Is upgrading from Direct Impingement (DI) to a short-stroke gas piston system worth the money? We break down how the piston system works, its pros (durability, cleaner operation) and cons (proprietary parts), and whether it's the right choice for your AR-15 build.
