Customer Ratings & Reviews
Magpul STR carbine stock is Excellent
The Magpul str Excellent stock. I've tried many different stocks over the years, and this one is definitely at the top of my list. Great features, locks uptight. Not to mention, it's great looking, too.
Magpul STR commercial stock is Great
I bought this Magpul str commercial stock about three months ago to replace CTR stock because I wanted a better cheek weld. It went on fairly easily and sat snug on my commercial buffer tube. The locking mechanism is great and secures the stock to the rifle as if it were a fixed stock. It is the most comfortable stock I have ever put on any of my AR builds! In my opinion, of course. Now one issue people commonly report is there are no springs, so the batteries wiggle around. An EASY solution to that is to put a foam earplug in the battery tube before you insert the batteries. This gives them a secure seat, and they do not wiggle nearly as much anymore. That's a what, $1 investment at most for the earplugs?? Overall great stock, and high quality as you would expect from any Magpul stock.
