It feels better than my standart spring
Purchased along with BCM H buffer and works great.
Full BCM spring, buffer, stock, & tube setup is slick and silent. Noticeably quieter.
worked perfectly
Great quality
Quality spring. Definitely buying again.
All I can say is if you have a BCM buffer tube installed and use this buffer spring there will be no "spring noise" when hitting the bolt release.
All you could ask for in a 5 dollar spring
Needed shorter stiffer spring and this one worked perfectly. happy with purchase
