Launch a detent? Snap a spring? Don’t get mad, just fix it with this AR-15 Lost Parts Kit!

Alright, so y’all seem to like the FU-BAG. Like a lot. Which probably means there’s a lot of little springs, detents, and pins lying around in dark corners around America. But we’ve heard you asking for more. More ways to get you out of that hole after you’ve F***ed Up – Building A Gun.

Here’s our answer. To better fit the rage we’ve all felt as springs bend, cotter pins break, or when guns just plain stop working right, we’ve come up with a new kit for all those lost and wear parts your gun needs. The MOTHERFU-Bag contains a big mix of upper and lower parts for the AR-15 that commonly get lost, break, wear out, or just plain bend too far out of whack to use again.

As always, remember to wear your eye protection whenever you’re dealing with parts under spring tension. Trying to fix an AR with no depth perception isn’t the easiest thing in the world.
