I upgraded my Remington 700 Police in .308 win with this chassis. The fit and finish is top notch. I used the Magpul PRS stock and this chassis isn’t made for that stock. No problem I just drilled and taped one hole through the chassis buffer tube end and the buffer tube and secured the buffer tube so it doesn’t rotate. Did the same on top of the PRS stock with two screws so the stock doesn’t rotate around the buffer tube. The finished rifle looks sharp.

The design biases the first port to do the lion share of redirecting the expanding gas and therefore pushes extreme side blast and concussion to either sides. It greatly reduces recoil and great to be used when you are all by yourself but not so great to your neighbor shooting lanes at the range. If you shoot mainly on the bench at gun range there are other more "polite" brakes. I used it on my AR-10 and my rifle felt like a AR-15. Highly recommended.

I live in California and to comply with California gun law I choose to lock the magazine so I can keep all other features. To reload my rifle I have to disassemble the upper and load cartridges into the fixed magazine from the top. The extended takedown pin helps disassembling the upper from the lower much easier and quicker. I only installed the extended takedown pin and keep the standard pivot pin.

This is a great scope for CQB and medium range application. It compares very well in term of clarity and brightness to my Leupold 8.5-25x50 scope, Vortex HST 8-24x50 scope, and Sightron 8-32x56 scope. The 1x power is very so slightly more than 1x but still allows both eyes open view without eye strain. All stock photos and description from Bushnell website and Opticsplanet said the turrets adjustment is 1/2 MOA per click but in fact, the adjustment is 0.1 mil per click for both elevation and windage. Also, there are three small opposing set screws to hold the turrets in place and to reset them back to zero after sighting in. That again is not the same as in the photo shown as one screw on top of the turrets. Perhaps the scope I received, on 6/15/18, was the latest version. The turrets turn easily but not too loose that they get bumped off easily. Very generous and forgiving light cone (apparent field of view) your eye needs not be at one specfic distance from the eyepiece to see the entire view. The BDC reticle is easy to use. I always wanted to have a 1x scope for close range but my astigmatism wouldn't let me see any red dot as a well-defined dot even the $500-$800 red dot scope. The crosshair of the BDC reticle gives a good horizontal reference so I won't rotate my rifle out of horizontal and for that, a crosshair still beats a red dot in my book. I really think this is an excellent 1-4x scope especially for under $200.

There are things I like and dislike about this red dot sight. I like the tethered caps for windage and elevation adjustment. I like the motion sensing auto-on feature so it is ready when I pick up the rifle. I like the battery is housed in an easy access tray. I like the fine 2-MOA dot. I like it is very lightweight. I dislike the mounting screws for the battery tray, they were too thin and one of them couldn't be secured because the screw hole was already stripped. Not that big of a deal I just put a little blue loctite to hold the screw in place. I don't like the flip up scope covers, I never like any flip up scope covers on any of my scopes. Over all the Holosun HS406A is a fantastic scope, easy to use, easy to adjust, and hopefully, I don't have to use their lifetime warranty.
