I will clear this myth up again, the lacquer is not the reason you get stuck casings, the steel case does not seal as tight as brass does in the chamber which allows carbon to get around in the chamber where the casing goes into battery. So when you shoot a lot, the carbon causes the cases to stick in the chamber that can cause a number of issues when it trys to extract the casing. The reason they switched to a polymer coated round was to help the round to not corrode, as well aiding in extracting for a sticky chamber. Also a lot of people who use their ammo in their AR, good chance are their AR does NOT have a true 5.56 chamber as per mil spec. Many non mil spec rifles have .223 SAAMI Chamber. A very small few will use a 5.56 chamber. The barrel should be marked, usually in front of the front site base somewhere. If the chamber is .223 then there is your issue, as Wolf is 5.56 cased. If your going to buy a AR this is another good reason to go with a 100% mil spec rifle to begin with, reliability issues are more common with really cheap AR's. Also cheap ARs have a lot of issues with being over or under gassed because of their poor quality control which will make problems with wolf more pronounced. I have put well over 13,000 rounds of wolf through my LMT MRP Piston AR and I have not had a single issue with wolf. It also will not break a extractor because it is steel cased, the ammo is a very soft steel compared to a harden steel extractor. Even if it did, the cost savings of the cheaper ammo to train with over a 20 dollar part speaks for itself. The people that have claimed the ammo broke their extractors were again not mil spec rifles and did not have the proper 5.56 chamber. There are pros and cons with going with a cheaper AR but in my opine of owning both types it is not worth the headache to go with a non mil spec rifle.
