Blitzkrieg Components SPRINCO AR10 Carbine Buffer Spring

After extensive testing and evaluation, we have sourced the highest quality buffer springs from Sprinco USA that are properly matched in strength for 9mm applications. They have the strength, consistent performance and long service life that is needed. Stronger springs hold the 9mm bolt in battery properly and reduce reaward bolt velocity which is important for safety, reduced recoil and service life of triggers. The spring is a critical component of the 9mm blow-back system and you need the highest quality and the proper strength for optimal performance. Our Sprinco USA Springs are made from certified Chrome Silicon wire stock to ISO 9001:2008 quality standards to withstand extreme heat and high cyclic rate. This ensures consistency in performance through high round counts. They are precision wound, heat treated, stress relieved and shot peened for extremely long service life and then moly plated for improved corrosion and wear resistance. For the longest lasting buffer spring, these are the way to go. For 9mm AR-15s, we recommend this spring for our 9mm Hydraulic Buffer with barrel lengths of 7 – 16″ and with our 9mm AKTIVE Buffer with barrel lengths of 10″ – 16″. If you plan on running hotter loads or suppressed with the Hydraulic buffer with the longer barrel lengths, then you should move up to the Sprinco AR-10 rifle spring to better handle the stronger bolt push. This is also a great spring for any AR-10 .308 type carbine with a collapsible stock. Expected service life in excess of 30,000 rounds.
