But y tho?
I wanted to screw around with a MP5 sized gun, but didn’t want to buy a real one, since its a toy (as are real MP5s in 2022). I already had everything but the rail, flash hider, and optic/mount laying around, so it made sense to slap this together. I’m digging the thicc handguard setup, and may try similar rail panels on some of my real guns.

Nice setup! I bought an SP5 just because I had to have a real HK MP5 clone. But I also bought a SIG MPX with an 8” barrel and it’s the bees knees.

One thing to note about this optic is that you need to use the included tool to zero it. The small screwdriver I usually use with tiny optics and 2-smoke carbs isn’t quite small enough.
