Welcome to my blog, the Gratutitous Gas Gun Geek. I originally started this blog to follow my attempts at building from scratch a WA M4, but it has since evolved into many other projects in the gas airsoft world. Watch me customize some airsoft replicas to look unique. I also do gas airsoft repairs and custom projects as well. Contact me for pricing and options!

Expanding and Dreaming of Possibilities.....

Quad G back here, and I've got a few things to get off of my chest.

First off, I think I want to have a second build.  Yea, I know I haven't even finished the first, but after looking at tons of parts and waiving through page after page of pictures and videos, I have so many ideas for many projects.  On top of that, if I get the chance to use a CNC milling machine and a giant chunk of aluminum, the whole world is mine.  From LR300s to CM901s (Okay, I played MW3, so what?  It's a cool gun), I could have EVERY M16 VARIANT UNDER THE SUN.  I sound like a gun collector don't I?

This brings me to thought number two, I have thought about opening up repair services publicly.  I've seen a few people on forums do tech work and it seems like something I could do.  I have been hesitant to do so because of my school work and regulations with my college housing.  I don't want to endanger a future I could have if I could simply avoid it all together.  That being said, I hate not having any money to build cool stuff, so anything could help me out.  I enjoy working on airsoft replicas, so I wouldn't mind installing parts or diagnosing things.

Bringing me to thought number three, I have thought about building WA guns for other people.  It could easily make me enough money to finish my own gun in under a year if enough people are interested in it.  I would probably not make any money on parts, just labor.  I wouldn't even consider it labor.  This type of stuff is something I enjoy, so it isn't even work to me.  Pricing becomes an issue though.  I haven't priced out what my build is going to cost, but I am expecting it to be around $1,200.  I would not want to build something that WA, G&P, or someone else is able to sell.  There is no way in hell I would be able to compete with their pricing.  I would consider though installing or changing parts out for someone on an existing WA system.

Probably the first step in helping someone build a WA from scratch is to sit down over the phone, or Skype and talk about their rifle.  I would start from front to back and see if there are any parts they have in mind.  It would easily take an hour or two to develop a mostly complete parts list.  It took me a month to fully develop mine!  Half of the battle would be finding the parts though, but now that I have scoured the internet, I have a good idea where to find everything.

I put up a poll the other day about me offering my services.  Leave a comment below if you really do want me to build a gun.  I might consider it.  Keep in mind that it is probably going to cost $1,500 with one magazine.  I would also like to hear what kind of rifle you would build.  Who knows, maybe one day I will make an offer!

Last thing to say for this post is just one thing, I have a good feeling I will be expanding this blog to cover other gas projects.  I just got a moderately new M1911 that I want to make a few changes to.  Look out for that in the next few months.  A few different guns from WE and KWA are coming out soon, so I want to snag those for my collection and I do plan on posting a review.  Next time I will have a few boxes in tow, and look out for a WE M14 review as well.  Thanks for reading!

The Lower Receiver - Where the Magic Happens

The Gratuitous Gas Gun Geek here once again with part two of my list of parts.  The lower receiver is where all the magic starts once you pull the trigger.  An amalgam of pins, spring, and other small parts, the lower receiver is where many people can get hung up on when constructing a rifle for the first time.  Many of the parts in the lower receiver look similar to the real steel counterparts, so it help to have basic knowledge of the real steel M16  or AR15 can come in handy.  You don't need to be an expert, but looking up "AR15/M16 function" on Youtube can provide helpful insight onto some areas.

Now, another advantage that some people have is to access an already constructed Western Arms M4.  Since I now work as a Gas Blowback Technician at my local airsoft shop, I have access to a half working WA M4.  Like many guns out there, it looks like a complete mess of different components, but the fact of the matter remains, it is still mostly complete.  I was able to talk to the owner and took it home for study.  Within the hour, I had the lower completely stripped.  I jotted down every dent and every spring, making sure I didn't forget anything and reassembled it.  Sure it may be missing a few things, but at least I have a better idea for how it works.  Without further adieu, here is my list of parts for the lower receiver:

G&P VLTOR Metal Receiver
(Ordered)
G&P VLTOR style 5 Position Buffer Tube
(Not Ordered)
Tango Down Style M4 Pistol Grip - OD Green
(Not Ordered)
G&P Frame Parts Set
(Not Ordered)
G&P Steel Anti-Rotation Pins
(Not Ordered)
G&P Dual Sling Mount
(Not Ordered)
G&P Steel Buffer Lock
(Not Ordered)
G&P Speed Buffer
(Not Ordered)
G&P Steel Bolt Release
(Not Ordered)
G&P Steel Sear
(Not Ordered)
G&P Speed Buffers
(Not Ordered)
G&P Steel Hammer and Firing Pin
(Not Ordered)
RA-Tech Buffer Spring (Winter)
(Not Ordered)
RA-Tech Buffer Spring (Summer)
(Not Ordered)
RS VLTOR EMOD Stock
(Not Ordered)

You may be wondering why there are multiples of certain parts.  The issue that could arise is the frame set that I linked above.  According to the description, many of the parts of a reinforced aluminum alloy.  It doesn't matter if it is reinforced or not, aluminum will not be as strong as steel with the same part dimensions.  Granted, it is quite the expense to switch to steel, but the extended life is well worth it.  Certain parts don't have to be steel, like some of the housings.  They do not encounter the force or changes in momentum that other parts will.  If the steel parts end up failing, then the aluminum parts are there to back up until new parts can be ordered.

I also thought about adding a fourth function to my WA build.  Granted, the receiver is marked with only 3 functions, but RA-Tech made a four function selector switch to have safe, semi-automatic, 3-round burst, and fully automatic options.  It was originally designed to be able to turn a WA M4 into the similar Chinese T91, but I think it would be similar to a four function MP5.  It is quite easy to do, RA-Tech made the parts to drop right in.

RA-Tech 3-Round Burst Trigger Group

I'm still deciding whether or not to add the burst function.  If I would, I would be tempted to completely remake the receiver.  I have access to a milling machine, so I could machine out a lower receiver from a solid block.  Then I could have it anodized, and laser engrave new trademarks with "Burst" added.  It would definitely add a truly custom look and feel for the rifle.  I think for now I will just make sure I can get one working with standard parts.

The first packages should be arriving in the next few weeks.  Still can't put anything together, but that is what package number 2 will be.  Time to gather my tools.
