Great adaptor, love that is used Allen key for removal internal vs a wrench on the outside. If you can get the stock barrel nut free this is the one to replace it with!

I am very impressed with everything about this
adapter. I previously purchased another brand at twice the price but this one is better in every
way so it is the one I use. Could have saved some money if I would have got this one first.
