Adams Arms Piston Review
Shooters have been involved in lively and often raucous debate about the smoothness of piston guns as compared to the traditional direct impingement. However, they have no difference of opinion that piston guns are way ahead of direct impingement guns in terms of cleanness of shots. So, the main issue of debate between superiority of piston guns over direct impingement guns is about smoothness of the latter when compared with the former.
Many experts have compared these two assemblies from both tactical as well as competition aspects using units manufactured by Adams Arms and are not yet quite sure about what should be the final judgment. However, most of them feel smoothness is an issue that has been well tackled by Adams Arms.
Generally, experts have compared AR-15 accessories, that is, Adams Arms piston uppers in both short lengths and medium lengths and are unanimous that they run almost as smoothly as direct impingement systems. They were already near unanimous that they run cleaner over the direct impingement types. So, these new AR-15 Accessories helped shooters a lot to revise their opinion about this system and it is no mean feat considering the amount of apprehension shooters had before they could lay their hands on this AR-15 accessory.
Shooters have used thousands of rounds of ammunition through Adams Arms piton uppers and generally do not have anything much to complain about except, of course, in some stray cases, when after pumping 6,000 rounds of ammunition through Adams Arms mid-length piston, the firing pin became unusable. However, that cannot be linked with the quality of Adams Arms Accessories in any way.
There are also not any noticeable abnormal wear and tear such as tilted carrier or worn out buffer tube as one would except in any other run of the mill accessory. Further, in a welcome relief to shooters, these Adams Arms uppers do not need any regular cleaning and can be used without any tension whatsoever till at least 6,000 rounds are fired.
