For sale I have an AR-15 that is almost entirely built from JP components. If you are not familiar with JP, please see jprifles.com. JP is one of the very best AR rifle builders today.
The upper was purchased complete from JP. It has an 18 stainless barrel with JPs proprietary brake installed and perfectly blended to the barrel (it is difficult to see a seam). The handguard is one of JPs proprietary round handguards. The bolt and bolt carrier group is the JP Full Mass Operating System.
The lower frame is a Mega Arms Gator. If you are not familiar with Mega, they are the same company that makes the top tier Zev Glock clones. My son gave me the lower as a gift, otherwise I would have purchased a full JP rifle. The trigger components are JP. The lower utilizes JPs excellent Silent Captured Spring system. The stock is Magpul and the grip is UTG.
I see no visible wear on the rifle. I have shot approximately 500 rounds through the rifle, primarily for prairie dog hunting.
