These sights look really good on and off the rifle. They are well designed, with easy manipulation and adjustments for elevation, without the need for a front sight tool. There is an Alan bolt to secure the elevation and lock it in, or you can leave that loose. In that case, just spin the wheel on each to make your adjustments based on distance and windage. They are manual flip ups, no springs, which I prefer. Great value at this price.

I keep a few of these around, in my range bag, in my EDC bag, and in a pouch on my battle belt. You never want to have your rifle go down while in use, from a broken spring or fly-away detent, and these replacement parts along with trigger springs and a spare bolt are sure to keep you up and gunning. Also handy for new builds, especially when you're building a mutt, custom down to the pivot pins and adjustable gas block.

Huge window, easy to zero, and to put fast, accurate shots down range. Very nice red dot, and the glass is crystal clear. Just wish it came with a cover.

This pack had potential, but the harness system sucks. The buckles are cheap Chinese garbage rather than faster and look and feel like they will break easily. The shoulder straps are way too short, designed for a kindergarten child, and end at the front of your shoulders even when you ratchet the straps all the way. Then it leaves the waist strap wrapped around your chest, way above your belly button. To get the waist strap down to your waist, you have to loosen the shoulder straps so much they barely cover the top of your shoulders. And I'm an average 6' and 175 lbs, not a huge guy. I removed the waist strap and the sternum strap (since that was literally chocking me and situated at the neckline. I will likely cut the shoulder harness off and have to reattach it properly. The shoulder harness does have shoulder tension adjusters at the top of your shoulders, but the designers apparently had no clue the attachment point has to be several inches above where the shoulder straps are secured, in order to allow the tension straps to have ANY effect at all. The pack is great and made of very sturdy cordura with heavy waterproofing rubber treatment on the back side, but the harness makes the pack almost worthless. And the camo or whatever they call it isn't nearly as good as the picks, more a yellow brown base and it reflects sunlight, so likely shines in NV.

This receiver is beautifully machined outside, with clean lines and a great design. Unfortunately, the inside isn't machined and milled properly, or the nitride coating was slapped on super thick, as not a single bolt carrier group will fit inside it. Halfway in they jam. I have heard the same about NBS uppers that look exactly like this one (probably just rebranded but the same OEM). This is a one star or lower item, as it will NOT FUNCTION. Didn't find out for months as I didn't get around to building right away. Stay away from ASC products! Defective!

I think most of the people who purchased an MPX have this Next Level Armament ambi charging handle on them, especially those who got Gen 1 models that came with an old school T handle. I know there are two other manufacturers who make some nice ones, but this is really the cream of the crop. Even when Sig put ambi handles on the Gen 2 MPX, the handle had very small levers and feels almost fragile.

This NLA piece is robust and solid in your grasp, and the levers give you a significantly greater purchase area, which makes for quick, positive charging. This will be especially important should you ever have a malfunction where a casing is trapped in the action after it did not properly eject. These wing-like levers give you the ability to really rip on it without losing your grip. The texture likewise increases grip and improves functionality. The fact that the steel pins anchor the levers at the rear of the device rather than the front also increase leverage. It is a smart design.

Note: So far, I have NEVER had any kind of malfunction with my Sig Sauer MPX. But, if it should ever happen, especially when time is of the essence, I want a solid, reliable tool that gives me the ability to quickly clear it and continue firing the weapon. The Next Level Armament charging handle is that tool.

With all that said, it also looks “wicked cool”.

I purchased the Battle Arms Development enhanced mag release for 2 reasons: 1) it’s B.A.D. so I know it’s high quality, and 2) it matches the other Smith and Wesson Red parts I had made for a fully customized Pistol Caliber Carbine (PCC) that I built a while back. I had a Seekins Precision bolt catch and Ambi Safety custom painted, concentrating only on those controls when I built this rig, but when I saw this on special I decided to finish off the various switches and levers.

If you don’t have other controls, switches, levers, etc, painted, the red mag release is still a nice touch, making it pop. But when they all match it is even better. The tactile feel of this mag release is nice, with no rough edges, and four distinct ridges running vertically to provide positive grip. The button seems to have been dipped, as the red comes just around the inside edges but doesn’t go down into the threads. Nicely done. Too bad Optics Planet doesn’t allow pictures, as you’d surely see how nice it looks with the other components.

The Sightmark T-3 provides some nice bang for your bucks. It’s pretty sleek looking while it does its job perfectly. The glass is crystal clear, the 3x magnification is there when you need it, and a simple flip to the side returns you to the red dot or other optic you employ for close contact. The magnifier locks securely in both positions- it will not wander off from where it’s set. Also appears to be tough, taking bangs and jolts without issue. The adjustments to center on your other optic are key, and missing from the cheaper magnifiers. All said, I don’t see any need to drop $300 or more on a magnifier, unless it’s Uncle Sam (and thus the taxpayers) picking up the bill because you’re going into harms way for the good of the ole US of A.

The only Con I can think of is it doesn’t have a rubber exoskelleton, or even caps. I have kept the rifle in a sock in a safe when not in use though, so it hasn’t been an issue. In the field, I’d want at least some kind of protection for the lenses when I wasn’t expecting any trouble, or for transport.
