Ordered to replace on a custom build 45 raptor upper. Prior pin had either broke, or come out due to the higher pressure of this round. Guntec fit very firmly, and so far has held up great. It's a plus that it is cerakoted for durability. Product shipped quickly and on time

Pin fit perfect. Fit into BCG like a glove. Always like these pins better than the cotter pins. Easy to use and better quality than most. Seem solid and good steel. I have used this pin in several BCGs and it fits in all types.

Works much better than the stock retainer. Very easy to remove and place back in compared to anything about the stock one.

Used for a recent Ar10 build and works great! Quality value for the price couldn't ask for me!

Great pin, recessed pin, stronger than the original cotter pin. Bought 2 more for other BCG's
BCA –
These are better quality than a standard pin, but at nearly 10 bucks they are overpriced.
