This is a complete kit in 308. The upper will come assembled. It will include the pictured upper, with nitride bolt carrier group, charging handle, and a 308 lower build kit. The lower parts kit has a standard bolt catch roll pin, which will work with most 308 receivers. If you have a billet lower, you may need an extended magazine button for full function. To finish this kit, you will need a dpms style lower, or 80% lower.
