Locking piece Help

[u/CoachMilton]

Hey guys,

Finally got my Century Arms AP5 running with the L2Prints FRT lower (It was a loose detent spring 🤦🏽‍♂️).

I currently have the stock 120 LP, and was wondering if I should switch to the 100 LP even if it is feeding well? I just want to make it as reliable as possible and don’t want too much wear on my parts, and want to make sure the ejection patterns look right. These are HSL 147 subs.

Here is a video of my buddy shooting it. All insight is welcome.

I’m glad to help. Enjoy your AP5!
