Gas Block Genie – Install An AR-15 Gas Block The Easy Way!
Just spotted this on Brownells. Interesting, inexpensive and reusable tool for proper gas block alignment. Proper gas block alignment is on of those tasks on an AR-15 that on the surface looks simple and theoretically is but the devil is in the details. The first mistake novices make is to butt the gas block against the shoulder, this is wrong. The gas block is required to allow space for a handguard delta ring. Installing the gas block up against the shoulder on the barrel will result in a partially obstructed gas block and an AR-15 that may not cycle properly. The next area of concern is having the gas block level and perfectly aligned with the gas port. If the gas block is canted slightly the gas port will be obstructed and this too will result in an AR-15 that will not cycle properly. Fortunately the Gas Block Genie is here to make getting your AR 15 gas block properly aligned a simple task.
The gas block genie is currently only available for .750 barrels but other barrel diameters are coming soon.
Gas Block Genie
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.
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.
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
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.
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.
Transfer the mark you made in step 2 to the barrel through the slot in the Genie.
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!

A reader at 308AR.com provided us with a heads up of the AR15 Turned Parts Set available here. The made in USA AR15 Turned Parts Set is essentially an AR-15 Lower Parts Kit minus a trigger kit, pistol grip and bolt catch. This is great because AR15 builders and shooters often do not use these parts that are included in traditional lower parts kits.
The cost of the AR15 Turned Parts Set reflects the omission of the aforementioned parts. This kit also is a perfect spare parts kit to keep in your shooting bag. The cost is not the only reason to consider buying this kit. In an unusual step the manufacturer includes two tools to help with the installation of the the roll pins and front take-down detent. I don’t expect these tools would replace my specialized tools from Brownells they will, with proper use work for the the shooter needing the tools just once or twice. Remember to cover your lower receiver with masking tape anytime your installing the bolt catch pin!
GERBER SHORT STACK AR15 GRIP TOOL MAGPUL MOE PISTOL GRIP
My GERBER SHORT STACK AR15 MULTI-TOOL arrived from Midways Amazon Store in 3 days. The GERBER SHORT STACK AR15 MULTI-TOOL is everything I expected and more. You can see a list of features on the previous post linked above. No reason to repeat myself. First thing I notice is the finish. Feels exactly like a phosphate coated bolt carrier. I like that. The second thing is the tool is first rate quality in fit and finish. The GERBER SHORT STACK AR15 MULTI-TOOL is strong, hard and seems to be made with precision. So far so good.
Installation – First thing I needed to do was remove the bottom cap of the MAGPUL MOE PISTOL GRIP. Always a challenge for a guy with some physical challenges. Once the end cap was removed the Magpul supplied rubber tool holder needs to be removed to allow the GERBER SHORT STACK AR15 TOOL to fit properly. The GERBER SHORT STACK AR15 MULTI-TOOL sits about flush with the end of the MAGPUL MOE PISTOL GRIP. I was concerned the tool would rattle as that would be annoying to put it mildly. It does not. It’s actually a perfect fit.
All in all Im quite pleased with the GERBER SHORT STACK AR15 MULTI-TOOL. Be curious to see if other tools develop from this line.
Note: The GERBER SHORT STACK AR15 MULTI-TOOL also fits the MAGPUL MIAD series of AR15 Pistol Grips
The Gerber Short Stack is a compact AR-15 maintenance tool sized to fit into Magpul MOE and MIAD pistol grips. The Gerber Short Stack’s innovative three-piece design allows shooters to create multiple wrench configurations, allowing users to tighten and loosen the buffer tube, flash hider and other accessories. The Gerber Short Stack also features a front sight adjustment tool, a pull-through handle for OTIS cables, and scraping surfaces for the weapon system’s firing pin, bolt and bolt carrier. The Gerber Short Stack is compatible with Magpul M-LOK accessories, featuring a 7mm wrench and two-sided hex bits for M-LOK fasteners.
One of my pet peaves from folks who assemble their own AR15 rifles is the sloppy installation of the various roll pins the AR15 rifle requires. 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. Brownell 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 AR15 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 carefuly 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:
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.
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.
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 PINthe rest of the way a breeze.
