You guys have probably covered this, but I just found this section and am looking for info on the kit. Spare me on the NFA discussion I am aware of the rules. Just wanna know if anyone has it and how they like/dislike it.

I cant give you any direct experince on the Roni kit. But i do have one of the Fab defense KPOS kits for my SBR Glock. I picked it because it was a smaller package and had a folding stock which is cool.
I am currently waiting for the new Hera Arms Triarii kit to be available This kit looks to have potentional because it in a true drop in kit. It also takes AR15 stocks so many options there. It is much larger than the KPOS kit but no modifications to the pistol are required. I know my KPOS kit you have to replace the rear plate on the glock with the provided one that holds the charging handle. I think the CAA Roni is the same way.

No, unless something changed, the RONI has a CH unit that simply slips over the rear of the slide/rear sight before the pistol is placed in the shell –– literally installs in seconds.

I handled it extensively (fondled/droooled/etc.) at the NRA Annual Meeting and Exhibits last year in Charlotte and had a prolonged discussion with the designer. I was very impressed... enough so that I will be SBRing one of my Glocks specifically for this.

I got to play with a tan version for a good while and talk to the owner, and I was very impressed. Everything looks and feels better in your hands than it appears in the pictures. It was solid and light, seems like a very fun toy and potentially a practical go-to home defense gun. The safety was the only thing hokey about it... More of a gimmick than anything if you ask me. I'd probably find myself swapping the VFG out, too, but the one included works. I will probably build a suppressed one someday, but it's pretty low on my "want" list right now.

Lgunsmoker, Do you have any pictures of your glock sbr? Also where did you put the engraving on your gun?

Thanks guys. I handled one at the January Dallas Gun show. Course it had a blue gun in it, but I think I got the idea. It seems pretty cool. Just trying to figure the cost effectiveness compared to other SBRs. I like the idea and it seemed solid to me.

I too would like to know where to engrave the Glock. I'm assuming on the slide.

There will soon be a version of the KPOS that has a charging handle that snaps over the slide, instead of into a replacement backplate. This is not because it is better - the backplate system is better - it can remain on the pistol once installed. You just leave it installed whether it is placed in the KPOS or in your holster. The pistols iron sights can still be used in the KPOS as a result. Of course, the SIG versions do not use a replacement end plate. The reason we are doing this is for those that have drop-in auto sears that also replace the back plate.

The RONI can't use the same charging handle system because it is patented.

Bikeman, the KPOS was in development for a LONG time before it was released, due to issues with this type of system, both practical and functional, that needed to be solved. As a result, I know a good bit about both the KPOS and the other pistol-to-PDW conversions. I can give you some specific information by email or IM if you like. Keep in mind that unlike similar systems, the KPOS was designed for serious users, so if you are just getting something for fun, some of these issues may not really matter too much.

The Glock must be engraved on the frame. Here is an example:

Duh, it would be the receiver wouldn't it?

FWIW I have handled both long enough to become somehwat familiar with them.

Roni
Pros: Installs very quickly, has a few inches of LOP adjustment, and a place to carry an extra mag. Also, the fact that it comes with a safety device is definitely a plus. Its ugly as hell, but its simple and it works. Very lightweight.

Cons: Feels like it might break with heavy use. It is a polymer system, so obviously it will have less rigidity than a metal receiver.


KPOS
Pros: Very solid platform. Folding stock makes it a very compact package. KPOS has a much more solid grip on the pistol, making for a more consistent and repeatable zero. If looks are a factor to you, KPOS also is more aesthetically pleasing IMO.

Cons: Takes a slight bit longer to install. No safety mechanism.


If I got to pick one, I would say that overall I prefer the KPOS. It feels much more solid, and personally I prefer the way it is set up to the RONI.

Hope this helps

You must have been using one of the few early ones that shipped without the FGG-S-KPOS Forward Grip Safety Mechanism. It now is included with every KPOS (without an increase in price), and no longer needs to be purchased separately. Do you have a KPOS currently? If so, we need to get a FGG-S-KPOS grip to you.

You can see it in the photo in my previous post about engraving NFA markings.

Will it be possible to add the new snap on charging handle to the one I currently have?
I like the charging handle I have, it is very solid. I don't even mind(and kind of like) using the charging handlle without the KPOS kit. My issue was that I had an Advantage Arms 22lr conversion that I used often, so it was a pain to have to switch the back plate every time I switch slides. I always intended to get a second charging handle kit so I had a second back plate but I never got around to it. Also, the advantage arms slide does take the back plate and charging handle but has a little of slope in it once installed (The Advantage Arms backplate is not made to same specs as the Glock backplate but close). This doesn't affect the function one bit, but it does bugs me a little.
Is it possible to get just an extra backplate?

I too engraved mine on the frame. I will get pictures taken and posted in the next few days. I use my KPOS with a Glock 35 SBR and a micro Red dot sight. Since I have a Glock 35 I first had to take the front barrel shroud part off because of my longer slide. Then I realized I could just notch the shroud sightly so my longer slide worked(this notched out area is on the shroud on the inside and not even visible, ). So now I can use it with or without the shroud as I choose. I even use it from time to time without the barrel shroud installed to make for an even shorter package.

Also for everyones information, the two side rails are removable if you also remove the barrel shroud(part of the screws that hold on the side rails also hold on the shroud) Without the side rails the package is even more smooth and streamlined. I actually only keep the right side rail on mine to mount my flashlght and leave the left one off because I like the smooth side.
I know, I know, show me!! I will get pictures up this week!!

I got my KPOS kit came with the standard folding forward grip WITHOUT the safety. How can I get one with the safety mechanism?

Those with the KPOS:
Please explain the claims of additional stability. It seems the RONI and KPOS both attach to the tactical rail, and then have some piece that accesses the slide to allow the gun to be charged. What's the additional stability of the KPOS?

The KPOS attaches firmly to the full length of the pistol's rail, and then to the rear of the frame. Other designs either attach only to the front rail, or just have a space that the pistol sits inside.

Remember that on Glocks especially, the frames flex when fired. (This is why certain types of foregrips have slipped off of Glock 18s, resulting in the shooters' hands being shot.) The KPOS is designed to specifically deal with this issue. The KPOS is very accurate. There are a couple reliability issues that other systems have that are also solved with the KPOS. This is why it was released later than the others - a lot of time was spent working out these issues.

The KPOS and the RONI were designed for very different purposes, so again, this may not be an issue for someone who just wants something that looks cool. The KPOS was designed mainly for private executive security and also for deep-cover military or LE work, so the emphasis is on compact concealability, simplicity, total reliability, and accuracy. It is designed to work better than weapons like Micro Uzis in this role.

Other systems were designed to simply turn a Glock into a carbine, with lots of cool features like collapsing stocks, cheek pieces, mag holders, ability to use AR stocks, etc. This is all fine, but for the specific end users the KPOS was designed for, a short M4 or MP5 is a much better choice than a bulky system like that.

So the two systems were built for totally different markets - the KPOS for very specific security and military/LE users, and the RONI for the civilian market. Both put a stock and rails on a pistol, but if you need a compact, reliable system, the KPOS is the way to go. If all you need to do is turn your Glock into an AR for something different on the range, any of the systems will work.

I will send you an email. We do not list the KPOS version for sale by itself because it comes with every kit, but we can work it out. Also the extra Glock charging handle.

Oh, and the Advantage Arms kit functions fine with the extra weight of the charging handle? This was something I was trying to find an answer to.

Yes, the advantage arms kit functioned fine with the KPOS and with just the charging handle installed. I shot it quite a bit with my Gemtech Outback without an issue too. The slot where the backplate fits in the Advantage Arms slide is slightly differently shaped than a standard Glock so the KPOS charging handle fits and locks up nicely but has a little wiggle to it(the Advantage Arms kit backplate has square top corners, not rounded like a Glock or the KPOS charging handle backplate, so the rounded backplate can rotate a little when installed). Once in the KPOS the charging handle can wiggle slightly up or down but it didn't affect function.

I am going to get one of the Tactical Solution TSG-22 Kits which are Steel and will have a 15rd clip. Once I get my hand on one of these I will let you know how it works with the KPOS.
Edited, just found out the TSG-22 kit has a solid non-removable back to the slide, no removable backplate, so it wont work with the charging handle. Oh, well, the Advantage Arms kit does run well.
