JP Custom Buffer Springs and Silent Captured Springs
The "spoon over a cheese grater" sound emitted by modern sporting rifles whenever they’re charged or fired has always been one of the AR platform’s ugly blemishes and one we’ve worked ardently to eliminate. After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, we opted to design and produce our own action springs with a perfect centerless-ground and precision-polished outside diameter. These JP Custom Buffer Springs are an inexpensive way to see exactly why we have a reputation for having the quietest, smoothest rifles on the market.
Our pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the patented Silent Captured Spring in 2012. Maintaining all the benefits of our polished buffer springs and proprietary LMOS™ buffer, this combination buffer-spring assembly eliminates the friction of standard buffer components resulting in outstanding smoothness and sound abatement. What’s more, the spring is removable from the assembly for custom tuning, and both the AR-15 and AR-10 versions of the JP Silent Captured Springs are functional in rifle- and carbine-length operating systems.
