STD30 BSA Standard .177 Mainspring

BSA Standard .177 Mainspring

For Guns Over 40"

This is a replacement mainspring for the BSA flat section wire pairs that we used to have made.Unfortunately the wire is just too hard to obtain now so we have developed this alternative in round section wire which actually works better than the originals!

This spare fits the following models:

Standard Pattern .177s

Lincoln Jeffries .177s
