It's a decent bolt. A lot smaller than the stock one. The reason you get better airflow is due to the sticker that comes with the bolt from techt, with the stock bolt while shooting the air exit on the back of the bolt. With this the air goes to the front helping you with less air wasted. The bolt comes with total of 2set's of O rings. 1 set is on the bolt when you unbox the bolt, the 2nd set its inside the package. Remember to tune the hush bolt for excellent preformance. The sound signature is almost the same as the stock, maybe a bit lower.
1 bad thing with this is. If you get a paint inside the small holes on the bolt it's hard to clean it compared to the stockbolt. On the stock you can use a q tip, on this.... shoot it out.
Is it worth the money? For the small increase fps and less air wasted per shoot? Honestly no.

I put in the hush bolt and shot it side by side with my buddy's G6R with stock bolt. There was absolutely no noticeable noise difference.
