Standard Power Buffer Spring. Equivalent spring
load to a brand-new Mil-Spec M4 Carbine Spring. This spring will perform
reliably in any properly configured and maintained 5.56 Carbine, if you wish to
maintain the performance of a "fresh" Mil-Spec load spring without
concern for replacement. This is the best choice for shooters and purists that
wish to maintain the performance of most factory supplied new Mil-Spec springs,
but do not wish to be concerned with frequent replacement of same or do not
have the time or inclination to seek enhanced performance options. Just consider
it as permanent new Mil-Spec Spring.
NOTE - FOR USE IN CARBINE / MILSPEC LENGTH BUFFER TUBES,
NOT FOR USE IN A5 LENGTH OR RIFLE LENGTH BUFFER TUBES
Sprinco AR-15 rifle buffer springs are made from high
quality Chrome Silicon wire stock which is used in a variety of applications
from Formula One to motor valve springs which can see up to 15,000,000
compression cycles in a single race. This makes it the perfect choice for a
rifle which will see far less cycles than that over its lifetime. For this
rifle buffer spring to retain its strength, Sprinco heat treats, shot peens,
and treats each spring with a proprietary formula that retains spring
efficiency for as long as you have your rifle.
