Not stout enough - Armaspec AR9 Gen4 Stealth Recoil Spring

I think the product will work for some setups. It was not stout enough for my PCC 9. It cycles quick and is pretty snappy, but it does not reduce the recoil as much as my H5 buffer and Sprinco Orange buffer spring. It’s not that difficult to install with the retainer pin kept in if you want to try it out and are unsure if it will be better than your current buffer setup. It’s worth a try, it is a neat product.
