I am running this in a 7" barrel pistol build, it went in well (just make sure it doesn't get caught on the mag catch during install) and comes out relatively easily. Magazines fit snugly but are smooth to engage and remove. However I would recommend avoiding the ProMag steel magazines, they required sanding due to the gritty coating on the magazine and failed to feed properly for the first 4 rounds every time. Swapped over to MetalForm magazines, and have not had a single issue since.

I used this trigger in a competition rifle. The is zero travel, the instant you put pressure on the trigger, it fires, and reset is instantaneous as well. The 3.5lb pull is perfect for my preferences, giving just enough resistance to feel safe and provide a crisp, clean break. It also looks fantastic both in and out of the gun. I would strongly recommend this trigger for any number of purposes, but especially for any serious target or competition shooter.

I used this safety on a 9mm AR pistol build. I found it to be faster to engage and disengage the safety than the traditional selector switch, especially as a left-handed shooter. The was a nice tactile feel and audible click as you move it from safe to fire and back again, and the red ring lets you see clearly if the safety is engaged or not. I chose the stainless version and it looks great on the gun, a nice accent point above the silver trigger face of my trigger. I liked it enough that I used some stainless accent parts elsewhere too just to give the gun some character. And as for the most important part, the safety performance, with the safety engaged it feels every bit as solid as a selector switch, with no chance of accidental trigger pull.

I used the 10.5" barrel in a 9mm AR pistol build. Of note, because of the design of the chamber, this is similar in length to a 9.5" barrel, the chamber is considered part of the barrel length which adds that inch to the measurements, but not to the length of your gun. I used the Faxon 9mm Bolt Carrier Group with this on a colt-smg 9mm setup. With a very rudimentary bore-sighting the night before, this barrel drilled shot after shot, rapidly, into an inch grouping at 75 feet (the max distance possible at the range I was at) using flip up iron sights. I was sure I would have to fine tune my sights, but it was dead on to the laser bore-sight. Ran a variety of ammo through it from match grade to hollow point, to finally some basic Winchester white box ammo, all if it went right into the center of the target. Feeding was smooth as well. Extremely happy with the performance of this barrel.

I used this bolt carrier group in a 9.5" barrel AR pistol build with a Faxon 9mm SAAMI barrel, it ran flawlessly and cycled quickly and smoothly. This was Colt-SMG 9mm build rather than a Glock magazine build, however this will work for Glock magazine 9mm builds as well. I used a 9mm carbine buffer with a JP Enterprises .308 buffer spring, recoil was negligible allowing for extremely rapid repeated shots, all placed within an inch at 75 feet (the max distance possible at the range I was at) using flip up iron sights. I'm a left-hand shooter and even without a 9mm ejection port dust cover, casings did not hit me, they were ejected straight to the side. Very happy with this bolt carrier group.

I mounted this on a flat top AR-15 with the DI Optical Raven Red Dot Sight. It lined up perfectly and had great clarity. Rapid target acquisition was easy. It also cleared my folded back-up sights with no problem when in position. The mount is a bit difficult to swing out when not mounted on the gun, but once mounted it works quickly and easily with just a firm tug backwards followed by rotation to the desired position. Build quality is excellent, you can tell it's well made the second you open the box and get your hands on it. Very solid and held in place with no problems throughout a few hundred rounds at the range. I was very satisfied overall with the performance.

I mounted this on a flat top AR-15 with the DI Optical 3x Magnifier. Clarity was good, no glare from the lights that were right above and in front of me at the range, and I could acquire the target quickly every time. Works perfectly with the magnifier as well, they align exactly, making longer range shooting a snap. Brightness adjustment offered plenty of options for any lighting environment (including a couple settings for night vision that I wasn't able to test). Build quality is excellent, you can tell it's well made the moment you open the box. Held zero throughout a non-stop full day at the range with no problems, every shot was dead on. The built in rubber caps are nice as the tabs above them hold them up out of the way like a flip-up cap (although you'll want to flip the rear one up before moving the magnifier into place). This is a great all-around red dot sight, especially combined with the magnifier.
