A few folks have asked how to remove the factory installed thread protector from their M92 PAP pistols. Zastava does actually thread the pistols and it’s a 26mm diameter x 1.5mm pitch left hand thread (M27x1.5LH is the short cut way to write it) under that cover. These things were installed for importation, ruin the look of the pistol and, fortunately, are very easy to remove if you take your time.

Now I used a Dremel with a cut off wheel. You could just as easily use a hand file. For me, I used the thread cover to protect the threads and did not worry if it got scratched. Cut a little and try to turn the thread cover. It will turn clockwise to be removed once the weld is broken. Note, if you decide to use a Dremel and are new to them, practice with your cut off wheel on some scrap metal before doing your pistol. They can hop around unless you know how to hold and maneuver them.

Dremel rotary tool with EZ Lock cutting kit for Zastava M92 PAP thread cover removal — I prefer cordless Dremels with removable batteries so I can swap them at any time but any rotary tool will work. You’ll need at least an abrasive cutting disc to cut through the small spot weld.

Removing Zastava M92 PAP thread cover for cleaning or modification — I couldn’t take the photo and cut but you go slow with the cutting disc and only remove enough weld for the thread protector to freely turn.

Shane's cool plum AK rifle with red Soviet flag background — Here’s the remaining weld on the front block. Note, don’t toss your thread protector as you can use it to safeguard your threads as you grind down the remaining weld.

Next, I put the thread protector back on and used a stone wheel in the Dremel to clean up the remains of the weld on the gas block. Again, if you are new, practice first. The stone wheel may look simple but they can make a mess real fast if you lose control. I’ve been using Dremels since 1985 – trust me when I say you should practice first. Also, I like Dremels and have used them for years. They have tons of corded and cordless models plus there are other rotary tools on the market if you expect to have very limited use and want to save money.

Zastava M92 PAP thread cover removal with a buffing wheel — I used a small stone and light pressure to remove the rest of the weld. Putting the thread protector back on will keep you from damaging the threads. Grinding wheels like to hop around if you aren’t very careful.

Cleaning Zastava M92 PAP barrel threads with a cotton swab. — While the steel is shiny and clean, use your favorite cold blue to stain the steel. I like Brownell’s Oxpho-Blue liquid.

Steel wool pad used to remove Zastava M92 PAP thread cover — Burnish it with steel wool, repeat and apply oil.

I hope this helps you out!

Sniper / Precision Rifles

Video: H&K PSG-1: The Ultimate German Sniper Rifle by Forgotten Weapons

May 22, 2017 RoninsGrips

When the H&K Präzisionsschützengewehr (German for “precision shooting rifle”) PSG-1 came out almost 30 years ago, I thought it was the most amazing rifle I had ever seen. Chambered in 7.62×51 it was the West German’s response to a decided lack of effective sniper rifles in their police forces after the Munich attack at the 1972 Olympics. The PSG-1 was a true precision rifle. All PSG-1 rifles must be able to put 50 rounds of match ammo into a 3.14″ (80,,) circle at 300mm which makes it a true one MOA rifle. As cool as it was, there were problems. It was incredibly expensive ($10K when it came out), complex, one and only one scope option, and a reputation for being very finicky. I’ll probably never get to own one and for that matter I would rather buy other things with that much money but it is a fascinating piece of firearms history.

Ian at Forgotten Weapons, who is both very knowledgeable and a great presenter, teamed up with a James D Julia auctions to make this video. He provides a rich history of the rifle, an overview of features and then goes into a very detailed disassembly with commentary about each part. For example, he compares the PSG-1’s bolt to a plain G3-style bolt and highlights the differences.

The video is 20:36 long and totally worth it if you are a fan of the PSG-1:

Here are links to websites with additional info on the PSG1:

Buy a big Neiko 10048A set of quarter inch driver bits and not worry about having the right one when you encounter something weird

May 22, 2017 RoninsGrips

You know the quarter-inch bit really gives you amazing flexibility 4 installing or removing different types of screws, bolts and even using some tools such as Spade bits and step drills. With them you can overcome the problem of having the right type of screwdriver to install or remove specialty security screws or even things such as Torx and Allen heads.

For the most part when I am using Phillips bits I stick with name brands such as DeWalt, Irwin, Milwaukee and so forth. What I have found is that cheap bits aren’t always very rugged and round the tips over very quickly compared to name brand higher-quality bits.

For security/tamper-proof bits and specialty bits, I have this large set from Neiko. The below set has served me well so far when I hit the “oh man, do I have a bit for that” moments when working on cars, guns and electronics:

In case you are wondering, here is what Neiko reports about their 10048A bit set:

The 100-Piece Security Bits Set Security bits set contains many of the most common tamper proof type security bit sizes, including tri-wing bits, torx bits, spanner bits, and hex bits. Security bits set contains: 1 – wing nut driver. 1 – magnetic bit holder. 1 – socket bit holder. 1 – 1/4-Inch sq. x 1/4-Inch hex x 1-Inch extension. 1 – 1/4-Inch sq. x 1/4-Inch hex x 2-Inch extension. 3 – clutch bits (No. 1, 2 and 3). 3 – torque bits (No. 6, 8 and 10). 3 – spline bits (M-5, 6 and 8). 4 – tri-wing bits (No. 1, 2, 3 and 4). 4 – square recess bits (No. 0, 1, 2 and 3). 4 – spanner bits (No. 4, 6, 8 and 10). 6 – metric hex tamper proof bits (2, 2.5, 3, 4, 5 and 6). 6 – SAE hex tamper proof bits (5/64, 3/32, 7/64, 1/8, 9/64 and 5/32). 8 – Phillips bits (0, 1, 2{5} and 3). 8 – pozi drive bits (0, 1, 2{5} and 3). 9 – slotted bits (3, 4, 4.5, 5, 5.5, 6, 6.5, 7 and 8). 9 – metric hex bits (1.5, 2, 2.5, 3, 4, 5, 5.5, 6 and 8). 9 – torx bits (T-8, 10, 15, 20, 25, 27, 30, 35 and 40). 9 – torx tamper proof bits (T-8, 10, 15, 20, 25, 27, 30, 35 and 40). 10 – SAE hex bits (1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32 and 1/4). Set includes plastic storage / carry case.

Based on my experience, for the price it is cheap insurance and it has saved me more than once so you might want to consider a set.

Iraq, Military

Video: Rare Weapons of Saddam’s Iraq 1979 to 2003 by jmantime

May 21, 2017 RoninsGrips

I like jmantime’s videos – lots of photos, organized and set to music. He assemble this video around the weapons found in Iraq during Saddam Hussein’s reign between 1979 and 2003. The video ranges from Tariq handguns and Tabuk rifles all the way up through through tanks, the Babylon Gun, rocket launchers and so forth. This video is only 14:39 video and worth the time given all that he has assembled.

I mainly focus on firearms:

Tariq 1, Semi-automatic pistol, 7.65x17mm
Tariq II, Semi-automatic pistol, 9x19mm
Tabuk, Assault RIfle, 7.62x39mm [Their licensed version of the Yugo M70]
The Golden Tabuks they found in palaces
Tabuk, Designated Marksman Rifle (DMR), 7.62x39mm
Al-Kadesih, Semi-automatic Marksman Rifle, 7.62x54R [Their version of the Dragunov]
AI-Quds, Light Machine Gun, 7.62x39mm [Their licensed version of the Yugo M72B1]

From there it covers tanks, self-propelled guns and so forth. All in all, it’s a neat video with lots of photos that jmantime collected.

Irwin Lock-n-Load Quarter-inch bit extensions can save your bacon

May 21, 2017 RoninsGrips

Irwin make some very nice quarter-inch drive extensions in different lengths that you can use for extending your reach of everything from screwdriver bits, socket drivers and even step drills. I have even stacked the units for getting into really bizarre locations. I have use them for everything from reaching down inside butt stocks to loosen Frozen bolts, to truck firewalls, to holding Spade bits while drilling custom holes for recoil absorbing mercury cylinders, and so forth.

They are not very expensive and are definitely something I would recommend keeping in your toolbox for those times you have to reach something that is set way back.

Video: Chinese Type 56 AK-57 (Shooting and History) by Forgotten Weapons

This is a cool review of an actual North Vietnamese Army (NVA) Chinese Type 56 AK. It was a captured rifle and brought back to the US. Ian of Forgotten Weapons does one of his usual exemplary reviews of the rifle and discusses its history.

Blazer GB2001 micro torches are very handy

May 20, 2017 RoninsGrips

I work a lot with plastics, paracord and webbing. Thus, I need to melt ends, heat small tools/probes to poke holes and what have you. I use lighters for a while but the problem was they didn’t generate very much heat. They were good for searing the end of a paracord but not quickly. Sometimes they quit it heat tools up enough to poke clean holes in webbing.

As usual I did some digging around and came across the Blazer torch as you see in the above photo. This thing is fantastic. I have used it for probably at least two years with no trouble. I bought this in 2014 and after hundreds if not thousands of clicks, the little piezoelectric spark unit is still working just fine – as is everything else. It’s just plain reliable.

It is refilled vs standard butane cartridges. You can save a bundle by buying packages of them off of Amazon versus from the local drug store, grocery store or whatever. Surprisingly the torch does not use a ton of butane fuel at a time. I think it is because the jet is actually fairly small. You can adjust the intensity and the air:fuel ratio depending on what you’re working on. I bought a six-pack of the few will you see in the photo and I think I have only gone through one and a half cans in a couple of years.

The rubber base is removable if you don’t need it and in the next photo you can see a clear picture of the butane fill port.

So if you are looking for a very portable small torch this Blazer has worked great for me and I recommend it so I am listing it below for your reference.

Update: 7/23/2018: It still works great. No problems to report and am still using it regularly for rope and nylon.

Update 11/28/19: The seals went out last month and it will no longer store butane for more than a day or two. Based on reviews on Amazon, I am going to try out a Bernz-O-Matic ST2200T and see how it lasts. I bought the Blazer on 11/29/14 so it almost made it four years,
