M4 Hop Ups and Inner Barrels

It is time to either upgrade your hop up unit or inner barrel but you don’t quite know how? Check out this quick “how to” video and blog to learn and save yourself some time and money for more parts later on!

This is the video from BRIANatECHO1 on how to remove the inner barrel and re install depending on what you need to see and learn. Also the second half of the video is how to assemble the Echo1 M4 hop up unit in case you bought a brand new one and it is all in parts.
This video and info will work for more than just Echo1USA products but all other Airsoft M4 rifles. The pictures below are from the same video and some more info in case you missed something.

Echo1 M4 hop up unit

The hop up unit is all taken apart and laid out on how the parts go together. This is how most M4 styled hop up unit are assembled for the one or two piece designs

Echo1 M4 hop up install

The small rubber nub will need to be held in place with silicone oil to keep in place as you work. Remember take your time and you will not have to force any parts together. Once aligned correctly and with the silicone oil all the parts will easily go together. The small silver washers with teeth inside can be bent while installing or removing and that is fine. Just make sure the parts secure the gears in place and keep them from falling off the hop up unit.

Once the hop up unit is assembled you will see and fully understand how the unit works which is a great feeling from doing it yourself. As noted in the video you can use a small shim for a gear but on the adjuster wheel to better hold the wheel in place and keep it tight to lock it in place. Another trick would be to use a white out marker to mark your favorite settings. that would only be if you use the MadBull Crawler barrel.

The M14 Series by Echo1USA

The M14 rifles have long been used for the DMR or Designated Marksmen Rifle in the real world and the same for the Airsoft world. Most Airsoft fields and events now allow the M14 series to have a higher FPS to truly match the power they have on the field and this allows for the DMR teams and even the sniper roles to happen and work on the Airsoft field.

Echo1 M14 rifles

There was first the full sized M14 with the faux wooden stock which is great for the field use with its very long inner barrel of 509mm and the full stock to house a large battery pack this made for a perfect DMR platform. The times have changed and instead of the open woods the engagement is now in the city and there is where the SOC16 comes into use.

Echo1 SOC16 barrel

The SOC16 uses a black polymer textured frame and a shorter barrel of only 455mm accompanied by a forward optic mount the user is able to shoot while on the move if needed. By doing this the user still has the firepower and range needed if upgraded but less rifle to get caught on objects while on the go.

Echo1USA M14 review

All three of the M14 rifles will come with the traditional rear sights that are fully adjustable for windage and elevation. It is always needed to have your rifle correctly sighted in and this allows you to do that.

Echo1Combat Master M14

The M14 rifle has become the work horse for the Airsoft teams and their DMR and it needed an upgraded look and feel to better suit the role on the field. This is where the M14 Combat Master enters the scene. The M14 Combat Master is like the SOC16 but with a modernized body. A full rail system on the front will allow for a bipod, laser and any other accesories that are needed. The long top rail and stripper clip section allow for the mounting of just about any scope or reflex optic. The M14 Combat Master is a tad more heavy than the older brothers and the front and rear sling loops are welcomed on the M14 Combat Master. The stock is no longer a traditional M14 or rifle stock but a M4 crane stock with a pistol grip to allow the user to be more at home with this rifle.

Echo1 M14 Gearbox

All of the M14 rifles use the solid Version 7 gearbox design that is made to fit inside the frame of the M14. With the streamline Version 7 gearbox in the M14 series this allows for a more traditional take down like you would find on the real rifle. This means for the upgrade options there are many to choose from when it comes to inner barrels, gearsets, cylinder sets and many more that can be found at your local store.

Sponsored Airsoft Team GSX

The word “sponsored” in the Airsoft world is used far too often and it no longer has any real meaning anymore for most players it seems. If the sponsored aspect means you get free products to just post a picture on Instagram then you are not aware of what you are supposed to do and the final goal is to help the community and not just yourself. How do I get sponsored? You will have to put others first and work hard without expecting something in return but knowing you are helping, it is a true passion.

GSX airsoft Echo1

The GSX team stands out for many reasons and the main one is how the team presents themselves on the field and off the field. Their goal is to help the players have a fun time from the brand new players to the experienced players. It is never about them and what gear they have but how much fun you can have on the field. Every weekend they do their part to help the Airsoft community grow by hosting the Bravo Games for the new and beginner Airsofters to show them the ropes and how to play and act on the field. These games encourage the new players to have fun and keep on coming back for more the following weekend and further build the Airsoft Community. This is a complete opposite that we see online where it is fun to over shoot the new players. Making a bad day for a new player or any player on purpose will make them reconsider playing the sport or getting into it.

GSX Echo1

Being a great role model is key when you are in front of the Airsoft Community and GSX does that. Recently they held a double weekend toy drive. Putting others before themselves is a great character trait and most would not have done that but they did just recently and in the past to help those in need.

GSX tech work

Todd – LMG which is the dad of the family team called GSX is also the tech for his team and the local players. He will show gearbox builds and parts to teach the younger players and the many others that follow the team on their social medias. Instead of saying his airsoft rifle is the best he shows you how to make your airsoft rifle just as good.

Echo1 GAT

The youngsters and kids that are getting into the sport need to have a welcoming experience. Many come from the video game culture and see their big brother playing airsoft and they want to join in. This is where GSX steps up to the plate and helps with loaner airsoft rifles to help get them started to have fun and not spend so much right away. This young player was having a great day for his first time and using the GAT that Todd tricked out.

GSX airsoft team

The GSX team will always post pictures of the local players either on the field in the action or after the games to show how Airsoft can be fun and what you are missing out since you are not there. If you have any questions about their upcoming games or events or just questions in general you can find them on their FaceBook and Instagram or YouTube.

So what does it mean to be sponsored in Airsoft? It means you give back to the community to help it grow and not just your gun collection and help others just as GSX does. Follow the lead from GSX and do your part to make Airsoft great again.

echo1 mtc3

Check out the status of the build here below as it is worked on and build over the weeks.

Brian at Echo1

Today I went through the warehouse and started picking parts I want to put into the MTC3 to make it a great rifle I would want to use myself. I will be using the Modify compression parts since they are the best on the market. I will be mixing the parts to get more air than the standard cylinder set. Using a full cylinder and not a ported cylinder to get maximum air when using a 445mm MadBull barrel. We practice the same concept in our Knight’s SR16 with a short barrel and a full cylinder to send those BBs flying for days as most people report and enjoy.

Echo1 contest build

For the gearbox I will keep the standard Version 3 shell that is a 8mm option. I am going by the classic motto of KISS; Keep It Simple Stupid. I will keep the the parts that are good and no need to spend more money replacing the parts just because. The Steel bearing spring guide that is stock in most of our rifles is a great part and no need to swap it out with an aftermarket unit which would be the same but only a different color. The piston is the Modify Ultra Piston and is my favorite. I have several of these in my other builds that have lasted years with heavy use. I have corrected the AoE on the piston with a spacer so I retain all the air volume. The piston and gear mesh is just about perfect of 98% and the second tooth was hand filed to be removed and the third tooth has been partially removed as well. The gears I am using are the Echo1 Gearset Torque that are 18:1 ratio for a snappy trigger response a a durable choice.

Echo1 contest Brian Holt

Since I am treating this like my own rifle I want to make it cool so I have installed the SPEED Airsoft straight trigger. This will give the MTC3 a little shorter trigger pull and a sweet custom look. The bearings and bushings in the MTC3 will be custom by not being a uniform set like most factory builds. I am using 8mm steel ball bearings for the Bevel and Sector gears and a solid steel bushing on the Spur gear which takes more force in the gear train. This setup will give me a higher ROF while being durable and when combined with the torque motor and lipo the trigger response will be really good.

Modify v7 latch

This is a cool trick I use. The Modify Version 7 anti reversal latch for the M14 is being used in the V3 shell. I drilled out the axle hole to make it fit. The reason being is that the longer axle will have more surface area and support on the pot metal gearbox which is just a molded collar and will break from high spring rates. With the axle going through it makes it stronger and the flat head tool release option which is on all Modify latches makes it much easier than the old hook technique to release the bevel gear.

modify anti reversal latches

The anti reversal latches as shown;(left to right)stock V2/3 latch, stock v7 latch and the Modify v7 latch. As you can see the original latch is much shorter and the drilling is needed. The stock v7 latch did start to bend from the M150 spring. The new upgraded Modify latch made with better steel will be just fine.

////SPORT////

Echo1USA contest gun

Now that the gearbox seems to be just about completed I will will shoot and test it and see if anything fails while I break in the spring and have it settle to a nice 500 fps with a .20. Using the deans plug on the rifle and a matching lipo to make this a complete rifle for a lucky fan. Now I have to think about a paint job of the MTC3..

Stay turned to my Instagram BRIAN_at_ECHO1 for more updates on the parts and things I’m doing for the build.

Opening the main compartment and you will find two fold over padded partitions to keep the rifle safe and secure. Once the items are inside the partitions the large velcro sections keep them enclosed and secure in their spot until removed. As you see the rifle being an Echo1 Platinum has been split for a smaller profile in the DEFCON CAB. The compartment is able to house a standard AR15 with a 14.5″ barrel or shorter and most optics attached will fit as well. The other side will hold the lower receiver and anything else you might need.
