Design an Airgun

Just a reminder — the Design an Airgun contest ends on this Friday, October 16. The winner will be the niftiest design that most people can build. The winner will receive the American Zimmerstutzen as a prize. I have to limit the contest to residents of the United States because of international shipping laws but readers from other countries are welcome to show us their designs.

The winner of the Design an Airgun contest will win the American Zimmerstutzen.

Godfather’s Gold Gun giveaway

Don’t forget that some lucky U.S. reader this month will also be drawn to receive the Godfather’s Gold Gun — an Ataman AP16 pistol designed by B.B. Pelletier. So, there is a lot going on this month! read more

  • Discharge sound
  • TSD Tactical black
  • TSD Tactical white
  • Summary

Today is the final test of the Sig ProForce MCX Virtus airsoft gun. So far we have tested the velocity and accuracy of 0.20-gram and heavier BBs with the 120 mainspring the gun came with. Then we swapped in the 110 mainspring that was also included and tested the gun all over again.

Today we test the accuracy of the gun with the 110 spring and 0.20-gram BBs. Let’s get right to it.

The test

I shot outdoors at 10 meters. The gun was rested on a sandbag. The Romeo5 XDR dot sight is still zeroed from Part 4.

Today we’re going to have a little fun. I know some of you would like to work on spring-piston airguns but you just don’t want to jump into the deep end of the pool — as in buying expensive tools like a mainspring compressor and parts that may or may not work as you expect. Today we are going to change the mainspring in the SigAir ProForce MCX Virtus AEG airsoft gun, and we will do it with two Allen wrenches — nothing more! This is a job any of you can do. Then we’ll test the velocity of the gun and see what impact the new spring has made. read more

  • TSD 0.28-gram Tactical BBs
  • ASG 0.30gram Blaster Devil BBs
  • Full-auto
  • Summary

Today I’m shooting the Sig ProForce MCX Virtus AEG  with heavier BBs than Sig recommends. You will be able to compare today’s groups with those from Part 3 to see which BB you think is best.

A discovery!

Before we begin I need to tell you about a discovery I made. In the last report the 0.20-gram BBs that Sig supplied with the gun were not feeding well from the magazine, nor were 0.25-gram Stealth BBs. In today’s first test I had the identical problem and discovered that it isn’t the BB; it’s the magazine. It does not like feeding the last four BBs when it’s in the semiautomatic mode. So, for all of today’s test I filled the mag with way more than the 10 shots I needed and after the target was finished I went full-auto outdoors in a safe direction with the BBs that remained. All four of the BBs I tested today fed perfectly that way. read more

  • Rock and Roll
  • Discussion
  • Summary

I said in Part 2 that there was a lot to test with this SigAir ProForce MCX Virtus AEG airsoft guns, and today I discovered I was understating the case. You’ll see why as we progress.

Accuracy

This is the beginning of the accuracy test and it’s good to remind ourselves what this airsoft gun is meant for. It’s meant for skirmishing, which means shooting people, not targets. However, the best way to get it on target and properly adjusted is still the old-fashioned way of shooting at paper.

HOWEVER

The However today is all the variables. I will be shooting many different BBs, adjusting the Hop Up and adjusting the Romeo5 dot sight — each of which makes the equation more complex. I did not think about that until I was well into the test. read more

  • Summary

I did a search in the blog archives and could not find another report I had written about automatic electric airsoft guns (AEG). I have done some large articles about AEG in the past for Shotgun News and for my own newsletter. I even wrote two articles for Pyramyd Air about the basics of batteries for airsoft guns — one in 2008 and the other in 2009. Those articles are still good today — 10 and 11 years later.

Spring piston

An AEG is a spring-piston gun whose piston is retracted (cocked) and loosed by a mechanical gearbox that’s powered by a small high-torque electric motor. To power the motor a battery is contained somewhere inside the gun. There is a great animation of how an AEG works on Wiki. read more

Why muzzleloading pneumatics and gas guns are extremely dangerous

I am answering this discussion topic today because nobody had figured it out when I wrote up today’s report last Friday. Maybe someone did later, but I will answer it here so everyone understands. And just to let you know — I didn’t figure this out, either. Dennis Quackenbush was kind enough to explain it to me.

A pneumatic or gas gun may leak air or CO2 at any time. If it did, and if its forward escape path was blocked by a bullet in the barrel and the rear path was blocked by o-rings, pressure would build up until something let go. The most likely thing would be the bullet. In other words, a muzzleloading airgun can potentially fire at any time — if it is loaded and if there is a leak. Since a leak can occur at any time unannounced, a muzzle loading airgun is very dangerous. read more
