Gents, I got an issue, I ordered a forward assist assembly and tried installing it and the roll pin just slid through. I know the roll pin should be .625 long by .093 in diameter. Has anyone heard of a different sizes for the F/A roll pin? Or I might have an over sized hole on my upper? I'll try to go to the hardware store and just buy the next few sizes up. I looked at my Vltor uppers and they are a different size, but a different style all together. I have nothing to compare it to. I'm hoping they just put the wrong roll pin in the kit. It came from AR Depot and they have been shady lately. I don't want to run around looking or some oddball size. Let me know if anyone has felt this pain!
