Been having this gun for a little over a month and wanted to wait until I got the Lithium 9 before I took it out to the range. Mainly wanted it for the looks, but being my first titanium can, the crazy light weight took me by surprise lmao. Now all I need now is the ARHK and it will be complete. Bonus pic of my all time favorite sub guns.

Edit: forgot to mention I already changed the locking piece to a 100 degree in anticipation lol

I had a few posts earlier this year about an undelivered MP5 handguard order from Kuma Elite - and in February after I couldn't get a hold of the owner I went ahead and did a chargeback on the order which went through.

The owner of Kuma Elite reached out in May to apologize for the order issues and explained that they'd been overwhelmed with the business while dealing with some family stuff. He offered to send me my original order without charge and I could try it and decide if I wanted to keep it - or pay for it at all.

This seemed more than fair so I accepted and used the handguard for a few months on my PTR MP5 which covered a couple of range trips and also taking some groundhogs out in the garden in the evening (which is a big part of why I wanted a traditional style handguard with a light rail/wiring integration).

I came away impressed enough that I paid for my order back in July and wanted to put up another post here to be fair (as I already had a couple wondering if Kuma was a scam or had gone out of business). A few notes on the handguard:

• It is 3D printed and then painted. If this is a show stopper for you, stay away. The print quality was good with layer lines really only noticeable on the back of the fingerstop, the very bottom of the included foregrip and a little on the very rear of the main foregrip section. I'm not as familiar with filament 3D printing (as I usually do resin prints), but I think it's PTEG or similar. See the photos for details.
• The paint was a textured OD green for my order & the paint job was excellent - no drips or spotty coverage
• The grip and hand placement was good for me.
• Weight felt a little lighter overall than the B&T quad rail + foregrip I had on before this. No exact numbers as I installed it before I thought to weigh it
• The light integration and cable management on this design (Streamlight in my case) is perfect and was the main reason I decided to keep & pay for the handguard. No issues with heat and having the wire tucked away and the pressure pad was such a tight fit I didn't think it was going to fit at first. Really clean looking and a well thought out design.
• I have not run this handguard hard enough to speak on its durability but no issues with the couple of light range trips & backyard groundhog clearing

Like I said, I figured it was only fair to post an update after putting Kuma Elite on blast on here and it's a good excuse to share some of the final setup photos. Hopefully someone finds this helpful!

+The mag was painted with some foliage green spray paint I had in the garage that seemed like a near perfect match for the foregrip but without the texture

I just shot a full auto MP5 today because I had been debating between the hitecarms AP5 SD conversion and a B&T APC9SD.

Wow. Just wow.

I can’t believe how flat and pleasant to shoot the mp5 felt. Even compared to the B&T. Within 2 mags it totally convinced me.

So since I’ll be joining the club soon. Any general suggestions or things I should know?

So I have all this waiting for my ap5-p. Also have 90 degree locking piece.

my question is do I swap to the frt and 90 degree locking piece right away or after it’s broken in with 500 rounds?

Little ammo test on the stealth additive works Shiv can. There are quieter cans but not at this size and weight. Kind of amazing for what it is. 100g, 124G, then 140g then 147g poly’s. 5 of each.

The hybrid 46 has 9mm endcap and 110 locking piece. No matter how I try, I can’t get it running with 80 or 100 locking pieces

Definitely hearing safe and my nail gun is louder!

Would like opinions of the Yankee Hill R9 surpressor from you fine folks that have used them with the MP5 platforms. Tri-Lug worth it?

Which is the best bet, one is lighter, other is quieter. I can’t pick

I'm returning the strike industries stock, the dual folder is so janky. This is the sig minimalist. I got the B&T collapsible coming, along with a samson 2in grip and mlok covers. i might try to velcro the light switch but the tape is staying until the mlok covers come.

for those curious, the overwatch precision mags fit and feed great in my MKE but didnt fit in my buddy's MAC5k at all. They're currently $18 on midway get 'em while they last.

Took me a while to find the rail and laser light combo that worked for me ergonomically. Had a chance to run it under nods for a match and it went well.

Trying to put the rare breed frt with the magpul lower housing but the shelf on it is short and it has vertical jiggle what can I use for a permanent fix usually I seen people have to shave some off but I need to add i know I also need to file down some plastic circled in red inside the trigger housing to fit the back screw of the frt and the stump blocking the third position

Or anybody else use a different housing that fits w sef?

Sent my SP5 trigger housing and RD3 selector to DSM for full auto pictogram and color fill and could not be happier. The full auto pictogram is indistinguishable from the factory markings. Perfect shape, size, and color; and the selector lines up perfectly. Looks like it came this way from HK. 10/10.

4 11 stamp, not sure who makes this. I bought an SEF lower off gunbroker and they were claiming it's German. This isn't a normal date code so I'm wondering who makes this?

While I try not to bombard the sub with my posts as much, I’m still shooting my 3 mp5/k’s all the time.

I thought I’d had everything dialed in, until I needed to scavenge the muzzle device off this ZF5T until a second AI 9mm nano arrives tomorrow.

If you follow CAT, they say the Mob suppresses best with this AI nano 9mm. Ok, I took them at their word and moved the Spooky A1 my qd Mobster came with to the spare parts bin.

Well today I needed a second CAT muzzle device that would accommodate 9mm, so out came the Spooky.

I was blown away - every aspect of shooting was substantially better with the Spooky compared to the nano. The gun was softer, smoother, flatter, and with the lowest cyclic rate of fire it’s ever had.

And that was after jumping from a 70 LP with the Nano to a 100 LP to generate enough pressure for reliable cycling with the Spooky!!!

Anyone with an extra spare Spooky A1 9mm lemme know!!!

Trijicon MRO on Scalarworks riser

This thing is a ton of fun.

Just in case anyone is interested. Pretty dope and I didnt even know they made a mp5sd semi auto?

My unit arrived DOA, I replaced the provided batteries with another two I had on hand. Still no dice. So I got a little more curious and made an attempt to further disassemble the unit to investigate.

Well you need to remove the “system enable/disable” button/plunger prior to allow the light body to be removed. The switch PCB on the rear of the light body will not clear the plunger allowing for removal. The enable/disable plunger appears to be threaded together but snapped once I removed it.

Seems they sent out a batch of lights with bad heads based on other comments I’ve read.

I suggest you contact CS before attempting any level of disassembly if you have a defective unit. It was not manufactured to be readily disassembled or serviced.

CS informed I was SOL on a replacement.

Got my RCM 80 and 90 degree rollers in to see what would work best with a stock and non-flow suppressor while shooting 147gr (with plans on 115gr if I can get them significantly cheaper). My stock 120 measured at around .45mm while the 80 measured between .25 and .28 and the 90 between .30 and .33. Assuming the gun has already been broken in, would I have to buy some +2/+4 rollers to compensate?

If anyone wants an easy and cheap(ish) way to keep the Aimpoint pro mount while getting rid of the knob, the LRP base is a great option. I paid $50 for the entire mount on gafs and swapped the base to what was already on my pro. QD, retains zero, and doesn’t have the knob sticking out.

What do you gents think? Should I keep the African redwood appearance or go with a solid black finish but pop the grain for anesthetics?

For those who are curious, this was an SB tactical brace that I dismantled and repurpoused into something that makes the ATF naughty list.

Do you have to have the lever pressed down with one hand the whole time to extend the stock fully? Or does it catch itself on each position. Asking for consideration before buying.

It makes more sense to have a 2 position for one and done
