So I seen the unf adapter found on Edgun west. Gave it a shot and I am happy with it. The install did require some modification to the stock baffle. Just a simple drilling of 2 small holes in order to fasten the adapter to it. This is a step that care needs to be taken in order to ensure that everything lines up correctly. There are also 3 set screws on the cap that retains the baffle. This was a nice addition that prevented any slight rotational movement if not locked in place. I toped it off with a Tatsu. The results are quite good. At least to my ears anyway. I never wanted to add the extra length to my Leshiy but always thought that a unf option would be nice. I have it set up in .177 currently shooting the JSB 13.43 grain monsters at 842fps. Have been very happy with the setup so far. I still think this is one of the best bush/truck/beaters out there. Its the simplicity of it that makes it so reliable and durable. This has been the only mod/upgrade I have done to it.
