Just got my FedEx package today. It's a high quality manufactures. Only one inch longer than my M3 stock shroud(700mm).
Whole kit only 8.6 oz with muzzle thread insert. The adjuster is 3.8 oz.
The kit comes with three different size muzzle thread inserts, .177/.22, .25 and .30 cal. These muzzle thread inserts can also put on M3 barrel shroud. It's a good news for M3 owner.
The barrel tuner have four o-rings inside the shroud cone. It is quite tight fit when insert barrel sleeve. The stock shroud only have two o-rings.
Some other details
