One of the ALG sling swivels I bought lost two of its ball detents. On the Brownell's product page there is a review by someone claiming the sling swivel arrived missing a ball detent. My question, is this common among all qd swivels, or just the ALG aluminum ones? I was going to pick up some Grovtec QDs, but if this is something I constantly have to worry about, I'll just grab some U loops or something.
GrovTec stuff is near perfect. I have 6 sets, recessed plunger, in use and great lockup, finish and I don't worry if it will stay locked in. Buy some. Solid product!
