I use them with my elite enkore.
They were reasonable priced and seem to pretty durable. Missed the target a couple times trying to sight in at 80 and landed into a fence post and it held up quite well. I built em with a 50g Hit insert.
That being said once these ones are gone I think I'm going to transition over to Sirius Apollos. For the price and the included componentry I really think they're a great value.
