Product Details
This is a Glock 34 Gen 3 slide that's ready for a red dot sight if you decide to add one down the road. It comes assembled with all the internals you need, plus a cover plate and standard sights, so you're getting everything in one box. The MOS system (that's Modular Optics System, just a fancy name for "optics-ready") gives you flexibility without any pressure to use it right away. Great if you're building a gun piece by piece or upgrading what you already have.
