I do not have one presently, but I did have one and it did work. Now, I'm as big a fan of Hesse as anyone else here, meaning not a fan at all. But, converse with him about it and you will get a list of obscenities, including about how dumb a person would be to buy one. He does not mince words, which can be a good thing, but he also can be combative and belligerent towards potential customers. And, tell me, just how does having a Hesse receiver affect attaching a muzzle device????? Evidently it did.
In any case, you will note that I have been fair with my description of him. He can be crotchety but he knows his stuff. That, my friend, is being far kinder to him than he can often be towards others.
