Shop AR-15 Parts for Sale

While we specialize in Glock parts like Glock back plates and Glock base plates, there’s no way we couldn’t give the AR-15 some love, too. Like Glocks, they’re incredibly customizable — but unlike Glocks, they were designed to be completely modular. Whatever you need your gun to be — handgun, SBR, hunting rifle — the AR-15 can be.

That’s why we designed our Cujo Muzzle Device in collaboration with OP1 Industries. This 3-in-1 device does the job of a flash hider, muzzle rise compensator, and recoil compensator all at once. Machined out of corrosion-resistant 4140 tool steel and adding an additional 1.575” of length, this AR-15 muzzle device is designed to be durable and improve projectile velocity. All in all, the Cujo is our AR-15 part for sale that turns your AR-15 into not just a gun but a formidable weapon.

MILSPIN is a Veteran-founded company that manufactures gun accessories from a workshop in Columbus, Ohio, using CNC-milling machines. We were sick of seeing cheap, low-quality parts flooding the American market from overseas, so we decided to take matters into our own hands and make parts ourselves.

In addition to our AR-15 parts for sale, our bread and butter is our wide selection of Glock parts. But if you aren’t looking for Glock mag extensions or 3D back plates, we also have an entire collection of EDC tools and brass knuckles for sale.

Frequently Asked Questions

Is an AR-15 worth it?

The AR-15 was designed to be a high-performance, reliable, modular firearm. But it’s become more than just a gun; it’s a platform. You can make the gun anything you want it to be. For its customizability alone, the AR-15 is worth buying.
Is the AR-15 bad for home defense?

Quite the opposite! If you buy the right AR-15 parts for sale, you can make an AR-15 that is perfect for close-quarters house combat. Consider an SBR or AR-15 pistol for this purpose.
Which AR-15 muzzle devices reduce recoil?

Muzzle brakes have the most impact on recoil reduction, reducing recoil and muzzle rise by up to 50%. Recoil compensators do similar. Something like our Cujo Muzzle Device combines flash hiders, muzzle rise compensators, and recoil compensators into one firearm, ensuring maximum accuracy.
