Product Details
If you've got an AR rifle and want to shoot something smaller and lighter, this barrel and bolt carrier group kit makes the switch easy. The 5-inch barrel in 5.7x28mm gives you a compact setup that's still accurate and fun to shoot, without the kick of a bigger caliber. Everything here fits standard AR rifles, so you're not rebuilding anything from scratch. It's a straightforward way to expand what your rifle can do.
