看看视频 - Lantac 的 "可调节缓冲 (Adjustable Buffer System, ABS)
用此来调节 AR-Cycling - 要比可调节 Gas Block 方便易行.

Whereas other companies have tuned the AR’s direct impingement system through methods such as adjustable gas blocks, lightweight bolt carrier groups, and lightened buffers, Lantac’s ABS system doesn’t require any armorer-level work or swapping other parts. Adjusting the collar increases the compression on Lantac’s buffer spring at rest, which results in a few things:
First, it increases the pre-load and helps to increase lock time.
Second, it allows you to adjust the system until the buffer no longer hits the back of the receiver extension, eliminating that aspect of the perceived recoil impulse to the shooter.
The secondary recoil impulse of the bolt going back into battery does actually increase a bit, but Lantac says that the overall effect on reducing perceived recoil is quite substantial. Lantac also says their system is tolerant of different types of ammo. We look forward to being able to shake it out. For the time being, Lantac indicated that their ABS system would only be available in their complete rifle builds and not sold separately - (SUCKs!)
