Two Great Videos Explaining How Roller Delayed Blow Back Actions Work

I’m a fan of the Roller Delayed Blow Back firearms for a while and have had opportunities to own and shoot ones from HK, POF, and PTR. I knew the rollers were locking the bolt head in place but never really understood the details of the action. I’ve tracked down two great videos to help show you what is going on.

This is a PTR PDWR in .308 – basically a cut down HK-91 style pistol with a SB Tactical SOB Brace and a Vortex Optic.

Forgotten Weapons

In this short video, Ian @ Forgotten Weapons does a great job explaining just how this system works.

MouseGunner

This is one of MouseGunner’s cool x-ray renderings where he shows the MP5’s action at work. He’s done this for other weapons as well and watching the weapon operate really helps.


I hope this helps you out. Be sure to subscribe to both guys’ channels – Forgotten Weapons and MouseGunner.

Great Deals On Pistol Braces and Pistols With Braces At PSA

When the ATF reversed the ruling about braces and enabled folks to use them however they saw fit, the demand and supply of pistol braces went into orbit. I have carpal tunnel and a hereditary tremor so for me, using a brace is the only way I can wield a heavy pistol – such as one based on an AR, AK or MP5 type of action.

Examples of Braced Pistols

SB Tactical’s PDW brace is great on AR pistols
IWI Galil Ace in 7.62×51 with a SB Tactical SBA4 adjustable brace
PTR PDWR .308 pistol with a SB Tactical folding mechanism and SB Tactical SOB brace

Palmetto State Armory (PSA)

PSA has come a long way. I’ve used them as my go-to AR parts supplier for years and now they have great deals on parts, kits, receivers, and firearms. They also offer some great deals on braces – by themselves as parts, as part of a kit offering or even on firearms.

Tips on Finding Decent Gunsmithing Tools on eBay

One of the challenges when starting out working on guns is building your tool collection.  It’s hard to find cost effective tools so you wind up making do with stuff, creating tools ad hoc, etc.  Interestingly enough, this is where eBay just might help.  While I’m not happy with their anti-gun position, there are a lot of tools that pop up there – ranging from low-end Chinese stuff all the way to some beautiful vintage tools.

So, I want to show some example searches with 20 live feeds from each section:

Gunsmith and Gunsmithing Tools

The trick is in the searching.  For example, here are the top 20 matches for gunsmith tools or gunsmithing tools and you will probably see a mix:

[ebayfeedsforwordpress feed=”https://www.auctionrequest.com/arfeed.php?uid=inf5efd3d98495c&keyword=%28gunsmith+tools%2Cgunsmithing+tools%29&sortOrder=BestMatch&programid=1&campaignid=5338063879&toolid=10039&listingType1=All&feedType=rss&lgeo=1″ items=”20″]

Of course there are brands I will steer away from such as NCStar and others that I will look closer at such as Brownells, Lyman, Tipton, Weaver, etc.  I also read the ratings of the seller.  If a seller has a good rating and more than 30 sales, that’s a good sign.  Less than that and you are taking a gamble.

Vintage Gunsmith Tools

“Vintage” seems to be a popular term for “used”.  You tend to find a lot of unique stuff that was made by a gunsmith to fit a special need as well as high-quality tools that were made with care vs. mass produced.  Be careful though.  I’ll zoom into the photos as much as I can plus look at the seller’s description and the rating of the seller to try and decide if the tools are in good shape or beat to death.

Used Gunsmith Tools

“Used” is still a popular term and is worth checking also.  Bear in mind the cautions I gave under vintage.

Brownells Gunsmith Tools

Brownells has been around a long time — they were founded in 1939 and have always been known for their quality tools, parts and supplies to gunsmiths.  Because they have been around for so long, you tend to see a fair amount of Brownells stuff hit eBay by name so that is worth searching.  Still look at the photos closely and the seller’s rating to play it safe.  By the way, if you have never read their Gunsmith Kinks books – be sure to pick them up.

[ebayfeedsforwordpress feed=”https://www.auctionrequest.com/arfeed.php?uid=inf5efd3d98495c&keyword=%28Brownells+gunsmith%2Cbrownells+tools%29&sortOrder=BestMatch&programid=1&campaignid=5338063879&toolid=10039&listingType1=All&feedType=rss&lgeo=1″ items=”30″]

Antique Tools

What is “antique” really is up to the seller.  You’ll see stuff that ranges from a few years to over 50 years old.

[ebayfeedsforwordpress feed=”https://www.auctionrequest.com/arfeed.php?uid=inf5efd3d98495c&keyword=antique+gunsmith+-%28ratchet%2Cair%29&sortOrder=BestMatch&programid=1&campaignid=5338063879&toolid=10039&listingType1=All&feedType=rss&lgeo=1″ items=”20″]

I hope this helps you out!  There is a ton of stuff out there if you experiment with the search terms some.

Switched to Super Lube Multi-Purpose Synthetic Grease For All of My Firearms

I’m always searching for better lubricants.  Many of the so-called specialty weapons lubes are just marketing hype with some bulk lubricant poured into their container.  In terms of greases, I’ve used quite a few over the years including wheel bearing grease and Tetra Gun Grease.  I wanted to find something effective, non-toxic and less expensive.

A name popped up when surfing – Super Lube.  To be honest, the first few times I totally dismissed the name because it sounds like some overly-hyped wonder lube that is sold in infomercials.  However, the name did keep popping up so I actually started reading up on it.

Super Lube products are made by Synco Chemical Corporation of Bohemia, NU, that was founded in 1980.  Their specialization is in the space of synthetic food grade lubricants and hold a number of patents.

There are a number of interesting characteristics about their grease that should be noted:

  1. It is designed to disperse very finely ground micron-sized PTFE (Polytetrafluoroethylene) which is a non-stick coating and lubricant.  You probably know it by the brand name of Teflon.  The approach they developed is one of their patents.
  2. It does not contain silicone
  3. It will work in a wide range of temperatures from -45 to +450 Farenheit
  4. It’s thickness is NLGI class 2, which means it’s about the same as vaseline or peanut butter.
  5. It’s non-toxic and food safe – here is the MSDS/SDS
  6. It will not melt or separate
  7. It will not dry out or get gummy
  8. It is waterproof
  9. It does not stain and is odorless – for you folks who do concealed carry or shoot a lot in uniform, you might want to take note of that.

Their website has a ton of information on Super Lube and also on lubrication in general if you want to spend some time reading.

I bought a 14.1oz tub of the Super Lube Multi-Purpose grease off Amazon for a whopping $11.50 and Prime shipping.  Very affordable to say the least.

To apply it, I use either a chip brush that I store in a zip loc bag to keep from getting dirty (as shown in the featured photo above) or a small flux / resin brush that I also keep in a baggy.

So, for the last few months I have been testing it.  When I cleaned one of my rifles or pistols, I would replace whatever I had been using as grease with the Super Lube Multi-Purpose grease.

I go by the old saying that if it rotates, oil it.  If it slides, grease it.  That is my rule of thumb so it goes on AK rails, bolt carriers, where the trigger hook grabs the hammer, etc.

It works great!  The weapons feel well lubricated after cleaning and they function great.  When I take them apart again for cleaning, the Super Lube shows no sign of breaking down, drying out, becoming gummy, etc.

If you are looking for an excellent affordable grease, check out Super Lube.  I’m definitely very happy with it.
