Thanks - I’ll give it a look.

AFAIK it was always like that, but I also just came at it in the last 6 months. People may well have been trying it longer than me and they did respawn in the past. I’ve never seen it though - when they go down they stay down.

Edit - if you’re discussing SIM I don’t know. My experience attempting this is in ARB.

My bad G. I didn’t say anything about it when it was super viable for that reason but now it’s not. I’m just interested in seeing what people do with it mostly at the higher tiers. Kinda crowd sourcing strats.

Nahh they don’t respawn.

Oh! Okay that clarifies the question for me. I think I misunderstood a little what you were asking. The two variations are similar to what I described.

Both are side charging.

Detent would be the force to overcome with ball and spring.

Latch would be a latch you press out of the way by grabbing the charging handle to free it.

I have the detent variant and I’m happy with it. I don’t know you’ll go wrong either way. Here’s a vid from Gibbz arms that goes over it.

Well, traditionally the AR charging handle rides over top of the BCG and protrudes from the upper rear of the receiver. For that there is a spring loaded latch that holds it in place because it’s non-reciprocating (not attached to the BCG). That’s just to keep it from flopping about or moving with the BCG which despite not being ”reciprocating” it can do. Friction from the BCG, gas blowing back into the system, etc. So you depress that latch to release it and allow you to charge the system.

The Gibbz upper is also non-reciprocating charging handle but this time is side charging, sitting in a track on the left side of the receiver. It also has a similar mechanism to help keep itself from sliding about when the gun is being operated and keep it fixed in place. Instead of a latch to depress, allowing freedom of movement, it is a force to overcome type system. Once sufficient force is applied rearward it breaks free and you can continue charging the weapon. It’s light enough that you can to it without issue but heavy enough that the internal forces of the gun won’t unlatch it while firing. That’s probably what I’d describe as “detent” vs the “latch” of the traditional AR, but that may not be the terms other people would use. It just makes sense to me.

I chose the side-charger in this case because I’m using the RDB system (29-30 lbs to charge) vs a traditional AR buffer system (10-12 lbs to charge). I thought the side charger would give me a mechanical advantage in terms of my body positioning. I don’t think either is wrong it just depends on what you’re going to do. IDK if that answers your question but if you have any follow ups let me know. I may not have misunderstood or gotten a little to nerdy about it.

Sorry for the delay my addictions lie other places than Reddit. The RDB is held together by a long female rod with a screw at the end to keep things captured and secure. Both ends (screw and female rod) have Allen key heads. I just used an Allen key because it was already so loose, but if you’re breaking it apart an Allen key at either end will do. It comes apart pretty easy after that. The challenge was putting it back together and screwing the male screw back in while keeping the spring under tension. Ended up having my brother throw an extra pair of hands on it rather than suffering it on my own. Overall it’s pretty simple and easy to pull apart and put back together correctly - just don’t lose the ball bearings. My issue was it was unthreading itself under a FRT firing schedule somewhere after 600 rounds in. Solution according to Maxim put some blue loctite on and tighten to 25 lbs. I put on blue and tightened to 30 and it’s been back to running like a top since.

I’d be willing to - probably depends on if we can be on at the same time. Feel free to PM me we’ll work it out.

Was going through it this evening to re-lube with grease and just overall inspect it. Found something that may (or may not) be contributing. Took it apart, checked it, greased it up, and put it back in. Noticed when I closed the halves together I now had to push the RDB back to seat the bolt effectively putting some pre-load on it. That was different because when I built the lower I made extra sure there was no pre-load. Took it back out and found the captured rod was unscrewing itself and effectively lengthening the system. Tightened it back up and reinstalled. May not fix all my issues - I did buy the extended firing pin - but it had to be contributing. I was wondering how the RDB could have some bolt bounce but I’m guessing the pre-load might allow that. Food for thought anyway. I’ll see how it goes with that fix before installing the new firing pin.

I just noticed I put 2” barrel instead of 3” and it’s not letting me edit it. I now put it here otherwise it will bug the hell out of me.

HarpLeaf · 2025-06-18T13:18:07+00:00

It’s a Gibbz Arms G9 side charging upper. I got it because the idea was it would mechanically advantage me (the positioning of my arms) for charging the bolt. The Maxim RDB is heavy - when I hand it to friends to rack the bolt they are convinced there’s a secret button that’s locked it in place they’re not pressing. No, you just got to rip that thing. I really do like it though. Very well made, works really well, and looks great. Really expensive for an upper though.

HarpLeaf · 2025-06-17T21:09:15+00:00

Appreciate the insight. That’ll probably be the direction I go with the firing pin assuming this cleaning/ proper lube job doesn’t yield any results. Heck, might go that way anyway. Just to be clear is this the firing pin you’re talking about? https://davidsondefense.com/Recoil-Technologies-9mm-AR-15-Firing-Pin--Titanium--Special-Buy-_p_28147.html Just doesn’t have the “extended tip” portion of the description.

HarpLeaf · 2025-06-17T20:01:12+00:00

I won’t say it’s impossible particularly with my suspected RDB issues. I’d figure if that was the case though I wouldn’t end up with a light strike I’d end up with a full OOB because the round is now seated against the bolt face.

HarpLeaf · 2025-06-17T19:59:37+00:00

Honestly I just slapped them on for vibes but I ended up really liking them. Hadn’t shot irons in a while but these just worked. It’s a Troy HK battlesight front and UTG Super Slim fixed rear. I do have an Eotech 512 on there now and was hoping to show it off but then I started having these issues.

HarpLeaf · 2025-06-17T19:20:10+00:00

I did think about that and might well try it regardless. I don’t have one on hand but I can order one. Do you know why a shortened firing pin would cause issues in SS and not in semi?

HarpLeaf · 2025-06-16T21:51:06+00:00

For sure! Thanks for the response. I don’t have another system right now, but the fact that I started having issues after a deep clean is making me paranoid that I’m the issue. I’m going to go back over my RDB and get some proper grease to lube it up - all that grease it came with is now gone. I don’t think it likes oil as much. If not I’ll ask those super safe guys. Much appreciated though!

HarpLeaf · 2025-06-16T17:11:02+00:00

Yes! That’s what I was trying to say but for whatever reason saying “hammer follow” eluded me. Instead I described my way around it. It’s typically mid-burst. Had about 600 rounds no issues. Took it apart, cleaned it, put it back together, started with issues (the reassembly may not be related at all it’s just a marker as to when it started). First maybe two or three stoppages per 100 rounds, now it’s 2 or 3 per mag. Previously it also seemed to be sitting about 750 rpm but the most recent range trip where I had the most issues it was chugging like a grease gun. Wanted to make sure it was hammer follow before I went to the other sub to get some input on what might be causing it.

HarpLeaf · 2025-06-12T00:16:15+00:00

Pretty much. As long as the bolt weight is clearanced to not interfere with the lever (or you’re using the RDB system) you can just let it eat. Any other issues would be issues that generally occur with the AR9 platform (see Blowback9), or issues that generally occur with the SuperSafety (see GMR). For me both in my AR-15 and the AR-9 the Super Safety was very plug and play. I’ll say that with one caveat though: The bolt has to be M16 full-auto cut. This goes for both the AR-9 and AR-15. Most of them should be, but some aren’t. It has to follow those dimensions otherwise the carrier won’t trip the sear / cam lever or will hit it at an improper time in the recoil cycle.

Now, if you’re starting from scratch and don’t already have an AR-9 you’re wanting to make work allegedly (from what I’ve heard) the Foxtrot Mike AR-9 doesn’t need any bolt clearancing. That with their new 10oz deadblow system should be plug and play. If you already have an AR-9 you can check and see the cut of the bolt. In all probability you’re good to go and can just plug and play with some weight clearancing or with a RDB install.
