Great springs - great price

These wee exceptional in quality. They fit right. gave the right amount of force on the pins and best of all, they came very quickly in the mail. I will probably order more of these for my other AR's as replacements.

Detent spring

Springs are a tad short

Mr. Dave
They work better than disposable lighter springs!

Somehow I lost my spring and accidentally grabbed a lighter spring. It worked, but was a bit weak. I figured I should order the real thing, because even stretching the lighter spring didn't yield satisfactory results. These new ones work perfectly.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
