Don’t worry about the detent that flew away

Nice for backup, once you purchase this you will have another spring fly away! 🤪

Great value

Great selection of oops parts, for a build or in a range bag for on the fly repair. You dont want to wait to order something like this until you need it. Great buying experience, fast processing and quick delivery.

Excellent spare parts

Bought this to complete a partial lower and have some parts for future repairs...if you don't want to buy a bunch of single parts this will work well...

handy

This is handy to carry in your range bag. One never knows when you will need to make a repair.
