Quarter Circle 10 issues?

[Rudras]

Just got my QC10 BCG in the mail. Slapped it in my upper and noticed some scratching noises. Pulled the BCG out to inspect and noted that the cotter pin protruding somewhat outside the bcg body. There were scratch marks on the top of the pin. Then upon even closer inspection. Noticed the "gas key" was not staked. Not sure if this slipped through quality control, Should i contact QC10?

 

 

Thanks for your input!

Staking on the Gas key shouldn't be an issue since it doesn't take in gas exhaust like a normal bcg. 9mm is a blowback and doesn't require the extra help to move the bcg. As far as the pin you can email them for a new one or just simply shave the tip with a file until is doesn't make contact with your bcg.

Even if you fix it yourself (that's what I would do) I'd let QC-10 know so they can look into it and make sure its a rarity and not the new norm.

The gas key is staked in the side not top. They don’t seem to shake them very tight as I had one come loose also and had it staked from the top.
