Project SA80 L85A2
Working out of town all week had me chomping at the bit with this project. I was digging up pictures on the net and making crude drawings in my note book.
These were from a guy on Facebook that goes by the name The SA80 Man. A message has been sent his way and hope he can help me with this project.

Does anyone else get bored when I’m traveling by plane? I have taken to putting my thoughts down on paper.
I was feeling confident and all was well and fine till I got home and hit upon my first major snag.
I had to work out the relationships between the magazine, hammer, and barrel exiting the front of the receiver. In order for all those things to line up I realized that the 180B bolt carrier is not going to work. It places the guide rods too low ( The receiver is upside down in the above pic) and they will not allow room for ejection. Several thoughts crossed my mind at this stage like cutting out and lowering the ejection port or raising all of the components to work with the existing port. I believe the first is still on the table but the second most definitely is not. The amount of work that would be required is considerable, including raising the barrel. Do that and the hand guards would no longer fit.
I think the simplest solution is to make a new bolt carrier. The SA80 bolt carrier guide rods are spaced further away from the bolt centerline and as a result, would solve all my problems. I am not sure how I would go about cutting the cam pin slot. I envision myself drilling a few well placed holes and finishing it off with hours of hand filing and fitting. Oh goody. Nobody said this would be easy.
The other option is to find more original parts.
Those who took a close look at the pics in my last post may have identified them as original SA80 parts. Those have prompted me to try my hand at modifying an Airsoft version to work as a real gun.
I ordered a WE L85 gas blowback from Evike and it arrived in a couple days. By the way if you sign up for their email list you get a code for 25% off your first order. I also got a coupon in the box for 20% off another order.
My plan is to start by taking it apart and seeing how the original parts as well as an AR180B bolt carrier assembly would fit.
Starting with the magwell I noticed this gun was different than the electric airsoft versions. The magwell was bigger. A standard AR15 mag fit. It’s actually a little loose. I may have to work the existing magwell a bit to tighten that up but I don’t see a the need to weld in a new one at this point.
Next I wanted to see how thick the steel was on the receiver.
Looks like the lower is thicker than the upper.
Lets start taking it apart and see how the parts compare. Plenty of room for the bolt carrier and fire control group.
Speaking of the fire control group, would you believe it drops right in like it was made for it!
Lets get an idea how the bolt carrier lines up with the lower.
Pulling the remaining guts out of the upper I can get an idea how everything might fit.
My plan is to make a trunion like the AR180B that just has a large hole in it and the AR15 barrel extension is pressed into it. I need to find pics of an original selector so I can wrap my head around how it changes from semi to auto. I can then figure out how to make it semi only. The auto sear has already been removed but there is something going on with the disconnector.
Let me know if you think this will work and if you have advice or pics or drawings please let me know.
Traveling for work can be difficult at times so I like to listen to podcasts to pass the time while on airplanes and driving in cars. Some of my favorites are “We Like Shooting” and “Joe Rogan”
I recently discovered a new podcast that I thought you might like as well. Tactical Pay Radio.
It’s brand new with only 3 episodes but I think it has a lot of potential and I subscribed right away.
In addition to the what might be considered “Normal” gun podcast content they feature stuff geared towards the business side of the industry. If you are looking to start a gun related business then I think it will be of special interest to you.
Give them a listen and subscribe. I know they would appreciate it.
That reminds me, I need to load up some content for my trip to southern Colorado in the morning.
Have a great week and I will leave you with a couple “What Is It Sunday?” pictures.
Let me know how you like the podcast and if you can identify what’s in the pictures. (If I got the stuff from you then you don’t get a guess) 🙂
