This design was inspired by the Gemtech Halo which utilizes the BFA grooves on A2 flash hiders for a mounting point. The STGW 57 has an integral non-removable flash hider which negates threading to keep the original appearance. Mounting was done by using two very tight fitting split rings to hold everything in tension and straight, the collar tightens the suppressor body down over the flash hider. The "flow through" function does work but I don't know how effective it truly is since I don't have another non-flow through can to compare it with; the gas pattern on the interior of the body and the cap plus a "low" amount of gas in the action compared to what I was expecting makes me happy with it. The end cap uses an angle grinder wrench for removal. All threads are left handed. The biggest detractor is weight. I originally intended for it to be made from T5 titanium but the cost of bar stock was way too high to justify for an experiment. Core, mount, and cap are 4140, tube is DOM. Finished in manganese phosphate. It could be quieter, but overall I'm happy with it.

Went for an older design on this one. Key takeaways are it is somewhat difficult to form baffles from scratch and stainless screen mesh is a pain to work it. I started forming the baffles from square sheet originally which was a poor choice resulting in tearing/shearing. Moving to circles helped a lot along with starting the draw with a large ball bearing then the male half of the die. Fusion welded and sealed.

This project was very easy and is essentially the same process as a PPS-43. Through drill the bolt, add a firing pin, put in the FCG, and it's done. The recoil spring system needed to be moved around a little to accommodate the hammer's swing, but nothing to invasive. Since I can't find a definitive ruling on which half is ATF determined to be the actual receiver, this uses a denial bar on each half in the same location to prevent FA parts from fitting.

It's kinda underwhelming but still cool to look at. The prototype pictured here is very ugly and slapdash but works well. Someday soon I'll throw a coat of black paint on it.

This project was relatively straightforward and was started primarily as a series of "What If's" that lined up well.

With the sunsetting of the 2005 dual use barrel import ban, I started to look for some stranger things to build that would've been "impossible" without the original barrel. The LMG-25 is a perfect example of this. The barrels are manufactured to incredibly tight tolerances in order to make the toggle lock action work, and they are a very heavy fluted profile to help dissipate heat during firing. When sourcing the kit I had a chance to inspect it in person prior to demill and came to the immediate conclusion that the addition of a Luger P08 style semi auto sear would be the right path to make this into a permanent semi auto closed bolt conversion. As shown in the photos, the bolts are nearly identical save for the "master link" on the LMG-25 bolt. Imagine a P08 was scaled up 250%, the action was rotated 90°, and chambered in 7.5x55 Swiss - That is essentially the LMG-25 at its core.

The reweld for this was challenging to say the least. Several internal geometries made the use of a jig possible, but it had to be 100% consumable and milled out of position after welding was completed. When converting to permanent closed bolt SA, the original open bolt sear needed to be removed entirely and it's opening welded shut. So now, instead of using a dual sear system as it was designed originally, one for open bolt and one for the firing pin, this uses a semi firing pin sear only now.

This kit also came with a full selection of accessories including the sustained fire monopod, AA sights, spare parts wallet, cleaning kit, both slings, spare barrel, bipod, and 4x magazines in the original leather carrying pouch. This is an incredibly accurate rifle even with off the shelf 174 gr ball. The recoil impulse is very pleasant due to the weight and buffer spring. After being rust blued, it looks very nice and is a real head turner at the range. I'm looking forward to building more of these in the future.

Overall I'm very impressed with the Lee. I've used their products a lot over the past 10 years but I heard hit or miss things about the 6000. It is an absolute dream to run compared to the Piggyback with a very low learning curve straight out of the box. All of the indexing issues I found during dry running as recommended by the manual were due to the primer seater, all indexing issues during use were due to the shell plate being loose. The auto drum is a little weird compared to the RCBS but works well once dialed in and lubricated with graphite. The best part of the 6000 vs piggyback is the priming system; it actually works without relying on 5 different adjustment points and is very intuitively designed. Being able to hot swap out primer trays is a huge bonus as well. The case feeder is nice too but I wish it had a tube "topper" like the bullet feed tubes. 200 rounds of 7.65 Para took about 1.5 hours from unboxing to the last round.

If you're still using an old progressive like the Piggyback, I highly recommend upgrading to the 6000. Obviously there's higher end presses and automated ones as well but the 6000 fits great for someone upgrading from an old/outdated progressive and wants the most bang for their buck on a budget.

12 GA 3" chamber, ejector. 13" bbl, 28" OAL.

I had some not so subtle feedback on my first design so I developed "Rev 2". The main complaint was light striking, so I made a much heavier hammer with an improved mainspring and tungsten firing pin. It is SAO and still chambered .22 LR and Short.

​

Already attached : Sling and fully adjustable bipod

Magazine carrier : 4x 32 round mags in an over-the-neck carrier which buttons into the Swiss combat blouse

Dust Cover : Simple piece of spring steel that's inserted into the magazine well when not in use

AA Spider Sight : The post rotates onto the rear sight leaf while the spider clamps on about 2/3 down the barrel shroud; meant to be used in conjunction with the tripod in AA configuration

Sustained Fire monopod : Capable of both rapid and fine adjust, can be utilized at either hard point on the stock

Spare Barrel Carrier : Contains the "B" numbered barrel and a barracks style cleaning rod

Spare Parts Wallet : Very complete set consisting of an ejector, toggle master link, toggle pivot pin, two firing pins, two sear/ejector flat springs, action screws, magazine release and trigger spring, disconnector (a complete one at that), oil bottle, and flat spring removal/mag loader tool/screw driver

Cleaning kit : Stiff nylon brush, brass jag, oil bottle, and a three piece string actuated cleaning rod.

These accessories were really thought out and even though it may seem like a ton of stuff, the Swiss defense doctrine of essentially running to the mountains to create a war of attrition made it make sense. All of these spares and tools would keep the gunnery team in business as long as they had ammo making it a really formidable set up compared to it's peers of the time which usually required armorer or depot level repair.

New tires/tubes, light bulbs, and a general once over was all it needed. Runs surprisingly well even though it feels like it's going to shake itself apart at top speed. First Italian bike for me, I've only had Tomos mopeds in the past.
