The MAC-11 short stroke buffer tuning pack is designed for MAC-11 blowback platforms. It includes five add-on buffers made from 95A TPU, which install in front of the stock buffer to reduce rearward bolt travel. This speeds up the cycling process and reduces the impact at the rear of the gun.
By adding thickness in front of the stock buffer, the bolt stops sooner, which can improve timing and reduce wear. However, incorrect thickness can cause ejection failures or other issues, so start with the thinnest buffer and test thoroughly before stepping up.

Product details
The MAC-11 Short Stroke Buffer Tuning Pack includes five add-on buffers in varying thicknesses: 5mm, 8mm, 12mm, 15mm, and 20mm. These buffers are designed to install in front of the factory buffer, not as replacements. Adding thickness reduces bolt travel, which can speed up cycling and reduce rear impact. However, incorrect thickness can cause ejection failures or out-of-battery detonations, especially when used with forced reset triggers.
- Material: High-quality 95A TPU
- Footprint: 23mm x 25mm for all sizes
- Installation: Place in front of the existing buffer
- Warning: Start with the thinnest buffer and confirm full ejection and reset before stepping up
