Description
One of the most common questions we receive is “What buffer weight should I get for my current setup to get a perfect ejection pattern?” While we can make recommendations based on our own experiences tuning guns, there are too many variables (barrel length, gas port size, buffer system, spring power, ammo) to be able to definitively say “x buffer weight is right for you.” In the past, customers have taken a stab in the dark on their buffer weight and had to come back for a lighter or heavier one after conducting test firing which can be frustrating and cost ineffective.
Buffer weights are changed by replacing one or more of the steel weights (~.65oz) inside of the buffer with a tungsten weight (~1.5oz). In the A5 buffer there are 4 weights and standard carbine buffers contain 3 weights.
A5 Buffer weights:
A5H0: 4 steel weights
A5H1: 3 steel weights, 1 tungsten weight
A5H2: 2 steel weights, 2 tungsten weights
A5H3: 1 steel weight, 3 tungsten weights
Tools required:
-1/8″ punch
-Mallet
To replace the a buffer weight:
- Using a 1/8″ punch and mallet, remove the buffer cap roll pin
- Remove the cap and weights inside of the buffer taking care not to lose the spring or rubber gaskets
- Replace the desired number of steel weights with tungsten weights
- Re-assemble the buffer weights and rubber gaskets ensuring that the weight with the spring is adjacent to where the buffer cap will be re-inserted
- Drive the buffer cap roll pin back in using the 1/8″ punch and mallet
