Nice finish on this barrel with a threaded square shoulder for a suppressor. You do need to transfer your locking block over from the original barrel.
Not very difficult and only requires a mallet and a
very small punch. I used a drill bit that fit perfectly
in the roll pin hole. Lockup is good and fit is perfect.

In the shooting world there are a number of choices for velocity/ES/SD recording. This Garmin unit is compact, intuitive and durable and has replaced my Chrony and Magnetospeed. I never bought Labradar because of price, complexity and
Issues with operation. I highly recommend the Garmin unit for getting more time behind the trigger and less time futzing with technology.
It even recorded the velocity of my pellet pistol when pistol mode was selected.

Garmin hit a home run with this product. Very easy to use and intuitive. Works so well it even picked up the fps on my pellet pistol at 467 fps. Automatic update upon receipt was quick and seamless. This unit does not require you to be a techie although a lot of us shooter are. This unit will replace two other chronographs. Highly recommend this product.

I just installed this on a Glock 40 and am very impressed with the features. The low profile takes a little getting used to but the sight is a good fit for the MOS model and is not obtrusive. I have previous experience with guide rod lasers and red dots. I like the green dot with the circle because the eye picks it up more easily and it can be very bright if you would like for daylight shooting.
This one is mounted with plate #5 but you have to remove the pins for it to sit flush. The one MOA dot does not obscure the aiming point for target shooting and the controls are easily adjustable.

This unit was very easy to install. Out of the package the unit was set at 3 lbs when installed.
I was able to easily adjust the unit with an Allen wrench to 1 lb 12 oz. Crisp let off with little creep.
This is the only aftermarket unit that fits in a Magpul Hunter stock or MDT LSS chassis without additional inletting.

As most of us know, the milspec triggers are gritty and have high pull rates. I have generally leaned toward single stage triggers of light pull weights but a while back decided to try the two stage in a couple of builds. The benefit that I see is you can take up tension on the trigger without release and then by increasing the pull a little more you discharge the weapon. These triggers fit well and are very smooth. My personal preference seems to be the flat unit but the curved one reviewed here works just as well. I have several of these now and they work quite well for improving the let off. Many hundreds of rounds have been run through this style of trigger without any malfunctions. By the way, they come with machined trigger pins that fit well, so no need to buy the antiwalk kit separately. This is one of the best upgrades you can do to maintain better groups with the modern sporting semisutomatic rifle!
