PSA M4 UPGRADE! 37mm Launcher, Red Dot & More!

We took the Palmetto State Armory (PSA) M4 in Flat Dark Earth (FDE) and gave it a serious upgrade! From improved ergonomics to enhanced optics and a 37mm launcher, this build is a beast. Here’s what we added:

✅ Die Free Kung Fu Grip – For better control and comfort
✅ Feyachi 2nd A Red Dot + Magnifier – Faster target acquisition with magnification when needed
✅ Magpul SL Hand Guard – Lightweight, durable, and M-LOK compatible
✅ Ordnance Group 37mm Launcher – Because why not?

Let us know what you think in the comments and what upgrades you’d add!
