Note: We sell standard buffers. If you are interested in the Spikes Tactical ST (T1, T2, T3) type buffers we recommend Brownells. See Brownells Spikes Tactical Buffers.
This standard weight carbine buffer is designed for ARs using a carbine length buffer tube. This is the lightest of the available buffers and is standard equipment on most AR-15 carbines.
Weight: 2.9 oz
This Heavy buffer, also known as an H or H1 buffer, is approximately 0.8 oz heavier than the standard carbine buffer. This extra weight helps to smooth the function of the AR15 by slightly delaying the unlocking of the action allowing pressure in the chamber to decrease, resulting in easier, more consistent and reliable case extraction.
The extra weight also causes the bolt to move forward with more authority, stripping and feeding the next round from the magazine into the chamber more reliably. This can be especially helpful if the rifle is dirty or under lubricated.
Weight: 3.7 oz
This H2 buffer is approximately 0.8 oz heavier than a heavy(H) carbine buffer and 1.6 oz heavier than a standard carbine buffer.
H2 buffer weight: 4.5 oz
This H3 buffer is approximately 0.9 oz heavier than an H2 buffer and 2.5 oz heavier than a standard carbine buffer.
H3 Buffer Weight: 5.4 oz
