Its been a long time, but im back

Ive just bought an Edgun Leshiy in .177, going to be using it for pest control. (250mm barrel)

Wanted to make it quieter..

Seen Custom Carbon Designs insert, but from what ive read people aren't raving about it... Saying "Save your money"


But for what...

For such a popular upcoming rifle, there doesnt seem to be much out there instock and for sale.

Wanted to keep the barrel profile (off centre hole!)

Advice and help needed.
Many thabks
