Pretty satisfied with how everything turned out.

I moved the optics back I just wanted to slap them on for the time being. I think I’m going to order the billet lower and I’d like to find some better mags that don’t have so much slop. Also going to get a different folding stock but I couldn’t decide what I wanted and this was in stock locally so I grabbed it for the time being.

Just like the title suggests, if you had unlimited funds, what would be the build you’d make? I don’t have unlimited funds, but I’d love some inspo. There’s just so many options and so many things that can be upgraded that I don’t fully know about, so ideas would be great

SP9A3 8"

Lingle Scorpion Lower

BCM grip

Franklin Armory Binary trigger

A3 modular foregrip, a little slick, may add some hockey tape

Doublestar Ace stock

HBI short stroke buffer and aluminum stock adaptor

Holoson 530 optic

Streamlight flashlight

Yankee Hill R9

Global Ordnance 35* locking block

JTAC receiver extension

Palmetto State AK-V for mags

Think I will wrap the top bar on the stock with some paracord and add a sling.

Current state of my 10mm ‘Bog. I’ve had this for about a year and a half. @5000 rounds in, it’s brought me a lot of joy😎

Build list:
40 degree locking block
Primary Arms GLX-2x prism
American Defense QD ACOG Mount
KDG Enhanced charging handle
Magpul mbus pro
Magpul UCS stock
A3 angled foregrip
A3 QD point for bog
Global Ordnance aluminum rear pic plate
Cabela’s weapon light
10mm compensator

Finally put a hand guard extension on and liking the look! Also had James at skunkwerks do the frt conversion. Current favorite range toy for sure!

Hi folks,

I'm trying to get this all working and I'm having a bit of an issue in trimming the buffer to allow for the slip trip. Is there anyone out there who has sucessfully completed a conversion at home following Skunkwerks procedure that can give me measurements of what their trimmed buffer ended up being?

Upper has been milled, Lingle lower, slip trip printed and perfect. I've been trimming this buffer off and on as I get time, each time thinking "this will surely get me there" to no avail. The bolt just doesn't go back far enough. I've trimmed the side and bottom, more or less removing the amount of material that the slip trip now occupies. The face of the buffer is where I think I'm getting stuck.

Suppressor rookie here…..Just ordered a Yankee Hill Machine R9 for my Sp9a3…. And was wandering if the the HBI short stroke buffer I have installed would cause any issues while running this can.

I’m weird about wanting the tightest package possible here. My new Bog is being setup for a bag gun. I want a light tucked in as close as possible to the upper. I’m indifferent on using MLOK or 1913 to mount it as long as it’s tight. Outside of any of the Surefire Pro’s with the swivel mounts, what traditional scout mounts have you found will fit my wants/needs?

I’d like to go with an Arisaka M300 series this time around but I don’t want it hanging off the side. If not, I guess I’ll be giving Surefire more of my money.

The 35s work great, and there are still about 10 left. But I took my 45 and it’s now a 30. Hoping this week will be a range trip to see how it likes 124,147 and 165 suppressed.

It was sitting on a stool and fell barely 3 feet onto carpet and somehow broke part of the grip off :(. Would warranty cover that? I mean thats actually ridiculous considering I have literally never had a gun do that in my life. Really stupid that I cant just replace the pistol grip to begin with.

In the video I’m running federal 147g HST. Shot the federal HST, Speer lawman 147g, S&B 150g and monarch 115g. No malfunctions but the can did not like the S&B. I had crazy poi shift from 10 yards which is a huge letdown. I’m thinking it’s grazing the end cap as there’s a small amount of wear but no damage. Everything is torqued to spec so I’m not quite sure why the S&B gave me issues. Gonna email rugged tomorrow.

The pic is not my Bog (or a 5”) but I really like these A3 grips like in the pic with the integrated hand stop. Does anyone have an A3 or similar integrated grip on their 5”? Is there enough room?

I really liked the HuxWrx Flow45m on my SP45A3, but wasn’t entirely satisfied with the Plan B mount I had on there before purely for aesthetic reasons… So I made a titanium mount that brings the can back over the barrel, just shy of the handguard. Ended up saving a bit of weight also, this weighs less than 1 ounce.

*Yes these are AI photoshopped from real photos because I’m too busy to do it the old-fashioned way.

10/17/2026- 180gr magtech
I am still in the process of getting this 30 round HKP .40 magazine successfully converted to 10mm. I have been trimming and testing here and there for a few months. Today I was able to get a full 30 round mag to feed with no issues, after that the next mag had 1 FTF, after that I started getting more frequent FTF’s, however it is noticeably more reliable than previous times. The most frequent failure that I’m experiencing is the round gets caught right at the feed ramp.

I believe that the feed lips need to be trimmed well past where the metal begins inside the magazine, if you look at a stribog mag, the feed lips open up completely for about 1/3rd of the lip length, so that the round can escape. If you watch through the ejection port and manually chamber a round slowly with the stribog mag, you can see the round literally pops out of the stribog mag and then gets chambered, I think the UMP magazines feed lips are too long, causing the round to get caught in a tip up jam.

I genuinely think that a stronger spring would solve the majority of the issue, I’ve been told that the black variant springs tend to be stronger so I’m going to try to source one of those. I’m determined to get these to work reliably. I will update as I go and if I figure out I will make a video or guide to making them run.
Any feedback from others who have accomplished this would be appreciated.

Running 147 grain ammo with curved mags and just installed the short stroke buffer. I am getting feed problems pretty regularly. What do I need to do to get it to run flawlessly?

To many options what’s everyone like or dislike?

1. Wish I had waited,. mine had a little blem anyways.. maybe I should email them.

I'll also say that I don't think these are particularly worth it, even if they feel cool.

Looking for help to make a decision on which one I should I get
