I picked up the V1 MARS FRT for my AK and overall I’ve had a pretty interesting experience with it. The biggest thing to keep in mind is that AKs can have a lot of variation between different manufacturers and receivers, so this isn't really a universal drop in part. Mine required some attention to get everything working properly, and I think thats just part of the deal with aftermarket AK parts like this. Once I had it installed, I was pretty happy with how it performed and it definitely gives the rifle a different feel than the factory trigger.

I wouldn’t say the V1 is perfect, and compared to some newer designs it does feel like an earlier generation product, but I still think its a pretty cool option for someone who likes experimenting with their AK. Just go into it knowing that different AKs can have different tolerances and the experience may not be exactly the same from one rifle to another. My experience has been pretty good overall, and I’m glad I gave it a try, even if it took a little more work than I originally expected

I chose the LE Latch Omni-Buster because my plate carrier and sling kept hanging up on the latches of my previous charging handle. This version has narrower, lower-profile paddles on each side, and I could tell right away that the snagging problem was gone once I started moving around my gear. Installation was still a straightforward, tool-free swap into my mil-spec upper, and the internal gas-fighting design — the raised shelf at the rear, the keyway notch, and the vent ports — matches what's in the standard Omni-Buster, so I got the same reduction in gas hitting my face when shooting suppressed or from my weak-side shoulder.

Construction quality held up just as well: the anodized 7075 aluminum shows no wear after regular use. Despite the trimmed-down latches, I was still able to work the bolt one-handed from either side without any hassle. Pricing landed around $70–80, matching the standard model, so the LE-style latches didn't cost me a premium.

The compromise is in the grip — the smaller paddles don't offer quite the same leverage as the bigger latches on the regular version, so running it bare-handed feels a touch less positive. Gas isn't fully eliminated either, just significantly reduced. Given how I typically use my rifle, though, this was the better fit for me.

I picked up the Breek Omni-Buster mainly because I run a can on my AR-15 and was tired of catching hot gas in the face every time I cycled the bolt, especially shooting off my support shoulder. It dropped right into my mil-spec upper with no tools, and I noticed the difference almost immediately — noticeably less blowback than my old handle, whether I was shooting suppressed or switching sides. Since it's built ambidextrous, I got that same consistent performance from either shoulder, which I wasn't expecting.

Build quality feels solid: hard-anodized 7075 aluminum, grippy latches I can run with gloves on, and it's held up well so far. At the roughly $70–80 I paid, it felt like a steal compared to other gas-blocking handles I'd looked at.

If I only ever shot right-handed, I might've leaned toward Breek's non-ambi Sledgehammer instead, and my unit's listed weight didn't quite match what I found online. It also doesn't kill gas exposure completely — just cuts it way down. Still, for what I paid, I'm happy with it.

Got out to the range to try the standard (non-ambi) Atrius Development Group forced reset selector in a pretty basic setup and figured I’d share what happened.

Rifle was a Smith & Wesson M&P15 running a Rise Armament RA-240 trigger with an H3 buffer.

Going into it I wasn’t sure if I’d end up needing to start swapping parts around or tuning things to get everything happy together, but that never happened. Loaded mags and just started shooting.

The biggest thing that stood out was how uneventful the whole session was—which honestly is exactly what you want. The rifle stayed consistent the whole time and never gave me a reason to stop and mess with it. No chasing problems, no adjustments between strings, no “maybe this next mag will tell the real story.”

By the end of the range session I had put 6 full magazines through it and realized I hadn’t had a single issue the entire time. For this particular combination, the M&P15 + RA-240 + H3 buffer seemed to work together really well. Once I got into the rhythm, it just stayed there and kept running.

I know every rifle can behave differently and results can depend on the exact parts used, but if anyone is curious about this setup specifically, my experience was straightforward: install it, take it out, and shoot it.

Final tally for the day: six magazines downrange and nothing to complain about.

As many builders in this space know, there’s nothing “plug-and-play” ready about a super safety selector. This Atrius was no exception.

While Atrius includes a "Lever Blocker" designed to cap cam travel and prevent over-rotation under the hammer, achieving flawless timing requires precise geometry. A major pain point for users centers around the mechanical tolerance between the lever cam and the rear of the trigger shoe.

Because of slight manufacturing variances across different lower receivers and trigger manufacturing batches, users frequently encounter binding. If the cam lever cannot pass freely behind the trigger group, the selector will lock up, or worse, the reset mechanism will shear under the force of the bolt carrier group cycling. Resolving this typically requires tedious tuning—either meticulously shaving material off the lever cam or carefully profiling the back of the trigger shoe.

My personal experience with the G-Lever perfectly mirrors these struggles. I paired the safety with a Geissele SSA trigger, expecting a relatively smooth installation given the "G-Lever" branding. Instead, I ran into severe binding mid-cycle. No Semi-Auto function, no Super Safe function. It was a one-shot wonder of an HK416 build.

To get the system to cycle without locking up, I had to take a Dremel and heavily modify the back end of the trigger shoe. I had to steadily grind away a significant profile of metal from the rear lower half of the shoe to create enough clearance for
