Is it worth doing this upgrade to semi fire Ar 15? This could cost $80 and I'm not sure it is worth the expense. The claim is that chrome silicon spring will last longer and perform best and the H1 tungsten buffer will slow the action and thereby aid in target acquistion and recoil reduction but I'm only going to be target shooting at slow rate constricted by range rules.
It is possible I'll upgrade the barrel to .308 so doing this might be a consideration anyway to reduce recoil.
If so, who has the best deal on spring and buffer? (There's actually a firm called Buffer Technologies?)
Thanks in advance
In target shooting spring life is not a big factor, but you can tune your spring for the best compromise between recoil and action reliability.
Many target shooters use weighted carriers or buffers in order to smooth out semi-fire action. The light carriers and buffers combined with a stiffer spring give better auto firing.
