In this post I will show how I go about Installing an AR-15 Single Point Sling Mount.  This is an easy project that a new AR-15 owner can complete with little experience.

I think it is an easy thing to add to the gun, and even if you don’t always use a single point sling you can keep it without adding a lot of clutter and weight.

Personally I prefer a 2 point sling based upon my marksmanship training in the Marines, but many people prefer the one point sling.

To do this modification you don’t need much in the way of tools, but you will need a buffer tube wrench which is a specialty tool tool made for an AR-15.

Installing an AR-15 Single Point Sling Mount

  • First remove the stock.  In the one I have there is a long screw that holds it in place, others have a nut around the buffer tube.
  • As you remove the stock beware that there is a long skinny spring that holds the detent pin for your rear take-down.
    • Don’t let that spring shoot out or get kinked up.
  • Unscrew the buffer tube,
  • Next add your AR-15 Single Point Sling Mount it goes between the lower and the buffer tube.
  • Screw your buffer tube back in.  Take care to ensure you do not cross thread the fine aluminum threads.
  • As you must take care that the spring that holds the detent pin is pressed in straight and it does not get kinked.
  • Tighten the buffer tube hand tight.
  • Screw on the castle nut snug using the buffer tube wrench.

Why a Single Point Sling?

To conclude,  I don’t think a single point sling is appropriate for all occasion.  Most times I thing a two point sling is better.  However they work well when you are working around vehicles.  It allows you to drop the gun and go “hands on” without losing your gun.  However, a single point sling it is worthless for carrying a gun long term while hiking.  Finally, it does not support the rifle while shooting like a 2 point sling can.

Installing a YHM Spectre Two Piece AR-15 Gas Block

Two part gas blocks are not needed in the majority of instances, they are more complicated and a little more expensive than the standard gas blocks.

However, sometimes they serve a purpose.  Today I need to install a YHM Spectre Two Piece AR-15 Gas Block because I plan on permanently attaching a large flash hider to a barrel and I will not be able to slide the gas block off if I ever need to change barrels.

By welding on a flash suppressor the gas block cannot slide off, this means i cannot change or repair my gas system.

This is really the only reason I can see for a block like this.

It needs an Allen key and roll pins to install.  You also need a vise and a vise block to support the upper as the gas tube is pinned into the gas block.

The only difference between installing this two piece AR-15 gas block and a regular one piece gas block is that it does not slide on, it fits over the barrel and the four Allen keys are tightened to clamp the block to the barrel.

When tightening the Allen keys be sure to tighten them like you would with a tire.  Alternate the bolts and don’t got 1,2,3,4.

How to Install Elfman Tactical Anti-Rotation Pins in an AR-15 Lower

Anti-Rotation Pins are normally not a necessary modification to an AR-15 lower, but their are some exceptions.  What the pins do is prevent the hammer and trigger pins in the AR-15 (or M-16) from rotating.  A steel pin in an aluminum receiver can rotate and elongate the holes.  This causes malfunctions and the destruction of a lower.

Normally the design of the pins prevents this, and a new lower doesn’t cost much more than the pins.  However, many people that own registered pre-1986 lowers for fully automatic AR pattern rifles add them because their lowers are irreplaceable.  If their lowers pins elongate they lost a machine gun.

I add one on my polymer lower because the hammer pins on mine wallowed out after less than a magazine worth of rounds.

One thing about installing the Elfman Tactical Anti-Rotation Pins in a freedom15 polymer AR-15 Lower, there is a strengthening rib molded on the lower that you will need to chisel off in order to install the anti-rotation pin.  It was not hard to do, but took a sharp chisel and permanently altered the lower.

I used to link directly to the item on Amazon so you could purchase it easily, but they have, in their infinite liberalism decided to remove firearm parts as they find them – they did this with tannerite also.

How to Replace an AR-15 Gas Block

I wanted to add a free float rail to my AR-15, but my A2 Style front sight was in the way.  I had to remove it and replace it with a a low profile AR-15 gas block.

This was not complicated, but it did take some effort.  Proper tools of good quality make this process much easier.

The recommended tools are:

  • Cupped Punch
  • Good Punch set
  • Hammer
  • AR-15 Gunsmiths block
  • Vise
  • AR-15 Upper Receiver block
  • AR-15 Barrel Wrench

Here is the basic process.

  • Remove hand-guards and upper receiver
  • Unscrew the flash hider and crush washer if present
  • Remove the tapered pins holding the front sight/gas block
  • Remove the pin holding the gas tube to the front sight/gas block
  • Pull gas block off end of the barrel – a block of wood may help is the gun suggest the block move.
  • Put the gas tube into the gas block, align it so the large roll pin hole lines up with the roll pin hole in the block.  Also you must make sure that the gas hole in the tube lines up with the gas hole in the block.
  • Slide the new gas block onto the barrel, be sure to line up the large gas hole in the block with the smaller gas hole in the barrel.  If the holes do not line up the gun will not work as a semi-auto
  • Tighten the set screws to tighten the gas block into the barrel

AR 15 Solvent Collectors

I am going to give you my opinion and tell you some common thoughts on the idea on solvent collectors but remember I am not a lawyer, am not familiar with the state laws of your state, and am not responsible for you getting arrested for breaking the law.

At gun-shows across the country, and all on the internet people sell adapters that screw to the barrel of your firearm on one end and on the other it is threaded to some device designed to trap cleanign solvent.

I have most commonly seen such solvent collector adapters for oil filters, soda bottles, and maglites.

I have also seen people adapt oil filters, soda bottles, and maglites into DIY firearm noise suppressors.

One of these uses is legal, the other probably is not.

Now I have, in the past owned one of these solvent traps, but the temptation of trying it with a oil filter was great and so I parted ways with it.

Because, unless you have the proper federal paperwork and tax stamp showing you have paid your money it is a federal crime to have an adaptor, a gun, and a collector with a hole though it.  The BATFE considers this to be an unregistered suppressor.

Now, you can make a legal suppressor if you first pay money and fill out the proper forms.  I really want to do a video of a maglite suppressor build.  I don’t because the BATFE has ruled that once the suppressor is built the entire device is a single non-repairable unit if a non-manufacturer builds one.  Meaning when I shoot out the freeze plugs that make up the baffles I am out the $200 tax stamp.

What makes this so irritating is that I have a friend that is a licensed manufacturer, and if he makes the same thing he can repair his (or mine if I bought it from him).

I don’t revolt against the law, but the confusing and nonsensical regulations that are not law but are enforced as law is the main reason I am 100% in support of dissolving the BATFE.
