Im building a 50beowulf and i was wondering where to find the plus 10% buffer springs ive heard about and how much they will cost? thanks and how much a difference doesnt it make, basically will it damage anything using a regular spring? thanks a lot

Bill Alexander advised me that the Beowulf was designed using mil-spec recoil springs ("standard power"), or specifically, mil-spec 17-7 passivated stainless steel. He also stated on the Alexander Arms FAQ page LINK that chrome silicon springs function to specification. The firearm will function properly with either spring just mentioned. He did advise that some benefits can be had for perceived recoil with heavier buffers (H and H2) for those who have a carbine-length buffer tube on their Beowulf. Here's another link for you to check out Beowulf.com

Wolff Gun Springs for the +10% spring. It makes some difference, but not all that much by itself. When used in conjunction with a heavier buffer or rate reducer such as MGI's, it helps tremendously.
