Super tight tolerance on alignment lugs and hardware. Beware that everything is held together with tiny screws. Nothing in most optics setups need more than 25in lbs torque, esp. Smaller srcews. Use blue threadlocker and a torque wrench. This is an expensive setup to He-man and ruin.

I used this while putting two builds together. One budget friendly (stag10 overstock sale rx set, larue tactical barrel, and ballistic advantage nib bcg, geissele rifle length super42 buffer spring and standard carbine length 3.5oz buffer in a bcm a5 buffer tube, +small parts and furniture. Came in just under $800) for my brother. And my nemo arms build ( nemo xo10 rx set, 16" nemo barrel, and this buffer/ bcg set. $3500). Both guns spec basically the same except the nemo buffer kit and my go to buffer and spring set up. I was much more impressed by my brothers build, recoil, reliability, weight, and speed were all better on the $800 gun. Recently converted my nemo build to my goto buffer system with a lantac bcg and now it feels like a $3500 ar10. This kit also showed up missing the ejector assembly. Nemo did respond immediately and overnight the parts. I love nemo, i don't care for this system in the 308. I've shot a nemo odim 300wm with this system and it's great. That's where it belongs and was developed for.

Works very well, just larger than I was expecting. As gar as function goes, I like it more than my surefire m640 and it comes with a good tape switch.

Button is so stiff its nearly impossible to operate. Waste of time and money. I just opted for the momentary tape switch it works fine.

This thing is huge and heavy. Takes up as much space and weighs as much as the light itself. $200 paperweight. Doesn't even properly attach. Just slips over the rail

I should've got the single dot model. I liked the idea of a bdc red dot but the bdc and horseshoe reticles flood the tube with red light rendering the optice completely useless. The chevron is so small ot might as well just be a dot. And the bdc dots are so close together that they just form a line. For now I'm just using the chevron only reticle as a dot until I can replace it with a romeo red dot.

Heard a lot of negative reviews on this peoduct but it was inexpensive enough that I thought I'd give it a shot. Mine functions perfectly and I haven't had one issue other than the ammo I want to use wont fit. On an ar10 platform you could run whatever you want, but this thing is a blast and a true multi-tool. Birds to squirrels and deer with slugs. Great for home defense as well. And my 70 yr old mother loves it.

For a $200 gas block the fit and finish isn't there for me. Functions as well as a $60 adjustable gas block. I found it more gimmick than an actual upgrade for a weapon you'd trust your life to. The "piston" that was installed at the factory froze up after the first day of real use. I had it on a suppressed 14.5" 5.56 and put about 200 rounds through it that day. After the first few mags I noticed it gassing a bit more so I tried to turn it down another click and couldn't get it to move. Took it apart that night ( pain in the butt on a gun with a rockset muzzle brake, thankfully I hadn't pinned and welded it yet.) and the piston was completely stuck. Took a blowtorch and wd40 to get it out.

It's a metal straw. It works as one might believe a metal straw should work.

Got this hoping for a primo addition to a very expensive build. Looks cool and has alot of gas mitigating features. When i tried to install it it wouldn't go inside the receiver. Upon closer inspection I found the guide lugs on the side of the stem were to tall. I tried it in a couple other receivers with the same results. I literally threw it in the trash then dug it out a couple hours layer to try to file the top of the lugs down and wasnable to make it work. After finishing the machining work for breek, it now fits and works as advertised.
