Functional but fragile

I like these enough to have 4, but I wouldn't count on them. It works really well for reloads, esp under night vision. That said I've broke 2, one was dropped on my driveway gravel, the other was broken while reloading. Hrf replaced them both for free but at ~$60 each that's a hard sell unless you've already set you're rifle up with essentials.

Easy reloads just like ur mom

Is pretty good

Only got it out for one range day at the time of writing but thus far I do like it. The added practicality was the driving factor for the purchase but it does look pretty bitchen too. I did file the top inside slightly just to try and make it smooth from the RCM to my AR lower but only to satisfy my smooth as glass brain. It’s attached to my SOLGW AR and I used both Pmags and OK E2s. No issue or complaints.
Also, shipping was stupid fast.

Solid upgrade

Easy install, great fit on Colt lower. Noticeable increase in reload efficiency. Buy with confidence.

Top 5 Upgrade

This tough-made, easy to install magwell makes for seem-less mag changes. Shave time off of your drills with this aftermarket upgrade, which almost instantly made the top 5 on my list of AR upgrades.
