These Bolt Catch Roll Pins work flawlessly. I also like to keep a few of these pins in the spare parts box. It's nice to see Optics Planet offer this item for sale individually. This is especially useful if you happen to lose the pin from your Lower Parts Kit during assembly.

FIT: The M-LOK mounting interface on this handstop does NOT seem to be machined to spec. The handstop did NOT fit the M-LOK interface on my ALG Defense EMR V1 M-LOK handguard. The handstop could be attached to the handguard but it would not seat properly against the handguard within the M-LOK slots. I will make an attempt to fit the handstop by filing its mounting lugs.

FINISH: The finish on this handstop is somewhat rough. Perhaps this may provide a slightly more positive grip, but it's unlikely to match the smooth finish of most handguards. I would prefer a more traditional hard-anodized smooth finish.

DISCLAIMER: This "GUNTEC USA" item was labeled "MADE IN CHINA" on its package.

PRICE: I feel this handstop is overpriced for an item that is manufactured in China, out of specification, and poorly finished. I can't say that I would recommend this item to someone else.
