About: "For God so loved the world that he gave his one and only son, that who ever believes in him shall not parish but have eternal life." …
Here is my last version of my M4A1. My previous versions had a problem of the bullet not making out of the barrel due to parts being in the way. I also tried to incorporate a new kind of magazine into this. Now for the Pros and Cons:

Pros:
Looks good
Fires 45-50 ft
Easy to use
Attachments
Realistic
Flip sight

Cons:
Uses some broken parts
