SLR15 Rifle Specs - Gas Ring
We use a one piece gas ring for SLR15 Rifle Levels 2 and 3. Level 1 SLR15 Rifles use a three piece gas ring.
The one piece gas ring makes the unlocking of the bolt more reliable during cycling operation.
It helps the gas bleed through the gas ring more consistent with no leakage in theory, thus again making cycling more reliable.
