Solid and well made.
Purchased one to replace a Black Rain adjustable and there's a night and day difference. There is actually space between the gas block and the shoulder on the barrel. The clicks on the detent are firm, just a little bit gritty, but overall, really good. The shape on the front is angled slightly forward instead of flat like the back, so be aware if you have a standard gas pin block to hold it while you put in the roll pin it won't fit. I used a 1911 gunsmith block to hold it for the roll pin. Overall very nice, especially for the price, I'll be ordering a couple more to have for backup to replace some of my others as needed.
