Awesome product! - OpticsPlanet Exclusive Spearhead Model S 19 inch .410 Bore, AR-15 Complete Upper Receiver

I always loved unique and versatile firearms. This upper definitely fits this category. within a few seconds, if you have an AR15, disconnect the 2 pins, replace the AR15 upper with this one, and you're all set! no need to buy or build a different lower. if you're on a budget, this product will save you the need for a lower. Already have a favorite lower setup with an awesome trigger/stock/grip that you love? use them with this upper! own an AR15 and need to switch it up to a small game hunting/pest control? 10 seconds and you are ready, with a .410 cal to do the job. the product works great. the build quality is good. had no issues with or jams so far. The product is great!
