I phoned wildcat rifles yesterday afternoon regarding having my evolution back bush machined to 20mm I/D. They took my name and address and said that if I send the back bush to them, they would do the job for me, no problem. Well, I was surprised when the post arrived this morning. A new back bush, free of charge, machined to 20mm as I’d requested. What great customer service. I can only recommend them highly. I’ve been very pleased with the moderator itself as well, well designed and finished in my opinion. Also very good performance. Just thought they deserved a mention. Excellent ?.
