About this stock
Sprinco Usa M4 Carbine Cs Reduced Power Spring Kits is a stock for AR-15.
Check what the stock attaches to. On an AR that means mil-spec versus commercial buffer tube; on a bolt gun it means the exact action, and whether the barrel channel matches your barrel contour.
California note: on a featureless rifle an adjustable stock is pinned in one position; on a fixed-magazine (MagLock or CompMag) rifle it stays adjustable. See the California Rifle Compliance Guide.
Manufacturer details
Reduced Power Buffer Spring. Sprinco collaborated with two prominent commercial ammunition manufacturers and two prominent gunsmiths to arrive at the design for the Yellow spring. It’s approximately 20% lighter than the White spring, and was the consensus choice out of 4 different evaluation samples provided to all parties. They all added in their final evaluations that if a particular gun needed a lighter spring, that the gas port should be enlarged for overall reliability. The Yellow spring is also appropriate for with low power SRTA training or SIMS Rounds for training operations.
