I received this as a gift. I read all of negative reviews on these & wondered what they were all about? So, of course I was a little worried when my wife happens to buy me one for Christmas to go with a new Aero slickside upper. It looked great! The machine work and anodizing looked great, and I wanted it to fit. So, before going through the trouble of winding the spring, I installed it on the rod by itself. Snapped shut perfectly and seemed to have the correct amount of tension when I snapped it open manually.

I installed the spring & now it will no longer snap shut? So I immediately know it's spring related. I take a look at the back and see the longer end has a slot milled in the back of the dust cover, but the short end of the spring is getting squeezed between the receiver & the dust cover. I simply bent a 90° angle into the short end of the spring, just low enough that it doesn't get squeezed between the receiver & the cover, and now it's perfect.

Timber Creek should remedy this by either milling a slot for both ends of the spring or bending the spring end like I did. But honestly, it took me longer to find my needle nose pliers than it did to diagnose & remedy the problem. I have a hard time deducting points when the issue was such a non-issue. Don't let a spring outsmart you. If you do, maybe don't tell the world about it?

In case you haven't noticed, your CMMG radial delayed blowback BCG used a cam pin with a round head. Just like this one. Noticing this when I first received my RDB bolt & barrel set, I immediately placed an order for one of these roller cam pins. My goal is to eventually run this thing supressed, so while building it I chose every part I could think of that might smooth out and quiet down the action as much as possible. I used this, a Geissele super 42 braided buffer spring, Kynshot RB5005 hydraulic buffer inside a PWS enhanced anti-tilt buffer tube. This is the smoothest cycling action of any AR I've ever laid my hands on. I can't say it's all due to the roller cam pin but a bearing rolling along the inside of the upper opposed to a pin just dragging along the inside of the upper would lead me to believe it's smoother cycling. I never used the stock cam pin, so I can't say. It's been in my grip from the start, just in case it ever fails. Close to 5,000 rounds through it and the roller is just as tight as the day I installed it. Nevertheless, I keep the stock cam pin in the grip for a backup.

It's so nice not having the pins hit the floor every time you remove the action from the stock. My only criticism would be that they should have dimpled the ends to keep your punch centered on the pins when driving them out. A lot of aftermarket AR takedown & trigger pins have been designed this way for years. Otherwise, all good!

Very nice fit and finish. Fits tightly to the trigger guard and is the perfect length to drop the mag without changing your grip. Anodizing is very well done and the price is better than most on the market. Perfect addition to my T/CR22.

Made In China. Just know that going in and treat it accordingly. Know that you'll probably want to replace the hardware at some point. Not only because it's metric & you don't want to carry 2 sets of allen keys in your range bag, but because they're also soft as butter. Replacement M-lok screws & nuts are readily available. Now, for under $15 I'm really impressed with this thing! The cantilever mount can be used on a handguard with limited space, or you can remove the clamp from the mount if you want the light tucked as close to the rail as possible. Little added bonus, you can add a 3-slot picatinny rail section to the cantilever mount if you want and run a separate component on that. It would start to become a little heavier at that point, but it can be done. Speaking of weight, it is heavier than I'd like but for mounting a backup light on a backup rifle it looks like it will do the job. If not, I'm only out $15.

Works great as a direct mount for a Scout style light or in conjunction with their V-block & rings for a regular weapon light. I've also mounted a Streamlight TLR-1 HL to it. Provides a comfortable place to rest your thumb, especially when used in conjunction with their AFG. Worked great with an A-2 sight, but if you have a pic-rail gas block and you're using folding sights be aware that you may run into some issues if those sights use a button to deploy or fold. The mount fits the light tight & that's great, but getting a finger between the light & the sight may be problematic. That was my only issue on one of my rifles so you may want to take that into consideration if you have something similar. Be sure to buy the correct side for your needs. If you're right handed and don't like a light in your sight picture, it's not too far of a stretch to activate the light over the top of the handguard.

Received this as a Christmas gift from my in-laws, great people, goes without saying. I explained to my wife that I would like a weapon light that I could swap across platforms and this is what they chose. I could not be happier! I know it's a bit large for the front of my Glock 19, but it will primarily be used on my AR platforms. I just like knowing that with the change of one bolt & adapter if will fit anything I choose mount it to. It will spend most of its time mounted to the bottom rail of my PCC just ahead of my Magpul AFG-2 where it can be easily manipulated. I really like the options of changing out the battery door and adding a tape switch if I choose to use it on another application. This light appears to be the most flexible on the market with options that you will not find with other models. The light itself appears to be very well constructed and throws a strong, focused beam. I have fitted it to everything I own with a rail and I like it more than a traditional flashlight in most of my applications. Especially where space is tight, such as a carbine-length handguard or a 9" rail, both of which I'm working with. I do not like the chrome ring around the bezel. I found an O-ring to remedy that.

Fits my Foxtrot Mike's handguard perfectly. Very grippy! I'll probably end up knocking down the high spots a bit with some fine sandpaper but I'll take that problem any day over something too slick. They lock down very tightly & I cannot see them going anywhere.

Tight fit under my Foxtrot Mike's handguard but man does it look great! I won't be using those front M-lok slots due to the tight fit but that's fine with me. I was a bit worried this would need bored out to pass a 9mm round but I read somewhere that it was big enough to handle the larger diameter round. The can part itself is just under 2.75" in case anyone's wondering. The machining and finish are very well done on this thing. The 1/2"×28 threads on my CMMG Guard barrel made it a little harder to find a muzzle device as most 9mm PCCs are 1/2"×36 but I'm very impressed with this piece!

Excellent fit & finish and very well built! Covers four M-lok slots perfectly giving me the most possible usable rail space on my 8.5" handguard. Enough to let me mount my Magpul AFG directly behind my Streamlight TLR-1. When no light is needed I have a QD sling mount out front without having to hang any extra junk on my rig.
