Gas Block Genie Gas Block Alignment Tool

Just spotted this on Brownells. Interesting, inexpensive and reusable tool for proper gas block alignment. Currently only available for .750 barrels but other sizes are coming.

Ever put together an AR build, only to find that your semi-auto cycling system just doesn’t cycle? Looks like that gas-block installation didn’t go as well as you thought it did. Avoid future frustration by adding the Two Two Three Innovations Gas Block Genie to your AR building kit.

Unlike other gas-block alignment tools on the market, the Two Two Three Innovations AR Gas Block Genie Gas Block Alignment Tool can be used again and again, as many times as you want, during your AR build. All it takes is three simple steps.

The type of gas block doesn’t even matter when using the Gas Block Genie. Whether you’re working with clamp-on designs, rail-block designs or micro-size options, the Gas Block Genie can handle it all!

Gas Block Genie Gas Block Alignment Tool Instructions

The Gas Block Genie quickly and easily allows you to perfectly align the AR-15 or AR-10 gas block hole with the gas port in your barrel every time.

  1.    Squeeze the Genie slightly to install into the forward face of the gas block so that the hole in the Genie is centered on the gas block hole. It may be easier to remove the rearmost set screw to do this. Part of the Genie should be sticking out the front side of the gas block
  2.    Use a very fine point marker or scribe to make a mark on the Genie where the forward edge of the gas block is. Make a small mark on the gas block at the slot in the Genie to indicate the top center of the gas block. It may be helpful to use a black marker on a stainless surface and a silver marker on a black surface.
  3.    Remove the Genie from the gas block and snap onto the barrel so that the hole in the Genie is centered around the gas port in the barrel.
  4.    Transfer the mark you made in step 2 to the barrel through the slot in the Genie.
  5.    Remove the Genie and slide the gas block onto the barrel.  As the Gas block approaches the barrel’s gas port you will see the line on the barrel and the mark on the front face of the gas block.  Simply align the two and you are finished!  A perfectly aligned gas block!

AR Ejection Cover Hinge Pin Clip Tool

AR-15 and AR .308 Ejection Cover Hinge Pin Clip Tool – There are a couple tricky areas when building an AR-10, 308 AR AR-15 etc. All are pretty easily tackled with special tools and patience. There is one part though rarely mentioned as being difficult but can give a builder fits (especially this guy with missing/short fingers). That part is the tiny c-clip on the ejection port door cover. It’s small and difficult to install with ease. Well the other day I was browsing Brownells gunsmithing tools section of their website when I happened across what they have labeled “AR Ejection Cover Hinge Pin Clip Tool“. It turns out this handy little gem of a tool is from a company called ROTOR CLIP. Rotor clip is a manufacturer of snap-rings, e-clips and yes the c-clip of the AR15 Ejection Cover Hinge Pin. Rotor Clip also manufacturers tools for installing and removing the previously mentioned fasteners.In this case the tool is a C-Clip Installation Tool manufacturers part number is A-300. I checked stock at industrial supply houses  as well as Amazon and Sears $46 was the going rate, Yikes. Brownells was half the cost plus I’m an edge member and have those shipping perks.

I think tonight I will go home and remove all the c-clips from my ejection port cover pins just to reinstall them just for fun.

308 AR Bolt Catch Screw | AR-10 Bolt Catch Pin Comparison

308 AR Bolt Catch Screw or Threaded Roll Pin

308 AR AR-10 Bolt Catch Pin – The bolt catch pin, one of the smallest parts on the AR 308, AR-10 and AR-15 platform weapons is a part that can stop an AR-10 308AR build dead in it’s tracks if you didn’t purchase the correct one or the correct LOWER PARTS KIT for your STRIPPED LOWER RECEIVER. Here’s why. The AR-15 platform  uses a roll pin and that’s taken for granted when shooters move up to the AR-10 and 308 AR platforms. Unfortunately this is where the topic gets muddy.

Armalite AR-10B Lower Parts Kit 10LRPK-T

Armalite AR-10 rifles use a traditional roll pin setup in the AR-10 lower receiver so their Lower Parts Kits obviously include the pin. If you use an AR-10 LPK on your non Armalite 308 AR you will need to order the threaded “Bolt Catch Screw” seen elsewhere on this page. I typically keep the Armalite LPK’s on hand as well as a few of the bolt catch screws.

Armalite AR-10 and AR-15 EL0220 Bolt Catch Roll Pin

The Armalite AR-10 utilizes this roll pin, Armalite part number EL0220 which is the same as their M-15/AR15 rifles. Alternatively DPMS LR-308 based weapon utilize a proprietary hybrid pin/screw (mentioned above).

DPMS AR 308 Bolt Catch Screw

The DPMS 308 Bolt Catch Screw is essentially set screw who’s threads have been removed from one end creating a hybrid screw type pin. Now unfortunately though not all DPMS LR-308 platform based LOWER RECEIVERS utilize the hybrid BOLT CATCH PIN. Some manufacturers utilize the roll pin method identical to the Armalite AR-10.

The process of installing the Bolt Catch Pin is probably one of the most difficult tasks for the inexperienced to perform. Not done properly it’s easy to damage the finish of your lower or worse, break something. Fortunately a little grease, a roll of masking tape and some special roll pin punch make it easy.  Visit our AR-10, 308 AR Roll Pin Tools Page

308AR AR15 AR-10 Roll Pin Tools

AR 308 AR-15 AR-10 Roll Pin Tools

308AR AR15 AR-10 Roll Pin Tools – One of my pet peeves from folks who assemble their own AR15 AR-10 308 AR rifles is the sloppy installation of the various roll pins the rifles require. In all fairness there are a few roll pins that present a challenge to the inexperienced and experienced alike. The BOLT CATCH ROLL PIN comes to mind as does the FORWARD ASSIST ROLL PIN. The BOLT CATCH ROLL PIN is positioned quite close to the body of the LOWER RECEIVER and requires a ROLL PIN PUNCH to have a flat side to properly install.

I have searched the internet shooting forums and websites as well polled user of my own forums for a better way to install roll pins. In that search I found some creative approaches but nothing that worked any better than my own approach of taping a ROLL PIN to a ROLL PIN PUNCH. Well that was then this is now. Brownells offers a ROLL PIN STARTER SET they refer to as ROLL PIN HOLDERS. The pins are available individually or as a set for just under $50. I opted for the set.

BROWNELLS 308 AR AR-15 AR-10  ROLL PIN HOLDER OPERATION

The roll pin holders are genius.  As seen in the image above the ROLL PIN HOLDERS are simply a punch that has a hollow tip the diameter of a given roll pin.  Place the ROLL PIN in the correct ROLL PIN PUNCH HOLDER and with a plastic faced or brass hammer carefully tap in the ROLL PIN.  To prevent damage to the the WEAPON stop hammering before the ROLL PIN HOLDER contacts the part that accepting the ROLL PIN. At that point switch to a regular ROLL PIN PUNCH, the type with a half round nose and finish driving the ROLL PIN flush.

NOTES ON ROLL PIN HOLDER USE

  1. Cover any part of your weapon with masking tape followed by duct tape in an area that could be damaged from ROLL PIN INSTALLATION. The masking tape serves as a great protector for your weapon. The underlying masking tape makes duct tape removal a simple process.
  2. Grease – I like to apply a small amount of grease in the ROLL PIN HOLE to help with proper installation. I also add a small amount of grease to the inside of the ROLL PIN HOLDER to help prevent the ROLL PIN from falling out and getting lost should I have a brain lapse.
  3. For finishing the BOLT CATCH ROLL PIN INSTALLATION I suggest the BOLT CATCH PIN PUNCH from Brownells. It is almost entirely flat on one side making installing the BOLT CATCH ROLL PIN the rest of the way a breeze.

Especially good on the tiny, tough-to-grab ones, or those in tight places. 1/16″ is notched to clear M16/AR-15 rear sight. 3.5mm excellent for holding the pin that retains the breech block on Sig handguns. Finish driving with roll pin punch. O/A in chart means “Overall”. Available individually or as a set of 5.
