Searched You Tube and found a code from Son of Liberty.
Use SONofLIBERTY for 10% off. Thanks for the idea @HoMiE
Ive had 2 of these from early in this thread. Also had the same issue with not be able to load the full 41 rounds, and as suggested, gave smack to the bottom, and it worked, and was able to get the full 41 after that. Only have 1 match on them, but no issues so far.
