  • 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.

My plan had been to try several 0.20-gram BBs, and then some heavier ones, since we learned in Part 2 that the Virtus can handle BBs up to 0.30-grams. But I didn’t take into account adjusting the gun and the sight for each BB. Were I to try to do that I could write about just this one airgun for the next month and still not finish. Perhaps you don’t care about the outcome but there are readers who want to know, so I owe it to them to do a thorough job.

Romeo5 XDR red dot sight

I mounted the Sig Romeo5 XDR red dot sight on the Virtus for the test. I must observe that both this sight and the Virtus airgun are precision-made and the installation of the sight took some time. All parts have to mesh, and when they do that sight is on tight!

I adjusted the intensity of the dot as low as it would go and still be visible. That gives the most precision. 

Sig BBs

I mentioned in the earlier parts of this report that Sig sent some 0.20-gram BBs with the gun, so I started the test with them. I first fired a single shot from 12 feet, and when the BB hit the target at 6 o’clock I backed up to 10 meters for the test. 

The Sig BBs were not feeding reliably. After loading the magazine each time it took several shots before they began to feed, so I loaded 16 BBs into the mag for the first target. That’s 4 pumps of the speedloader button. 

The first target has 8 shots on it. There were more BBs left in the gun but they wouldn’t fire out. The 8 BBs are in 2.415-inches at 10 meters. They are high on the target, and in line with the center.

Sig Virtus Sig BB 1
On the first target 8 Sig BBs went into 2.415-inches at 10 meters. 

I adjusted the Romeo5 dot sight five clicks down after seeing this first target. I also adjusted the Hop Up five clicks up. I didn’t know if that was the right way to go, but the next target would probably tell me. There were 4 BBs remaining in the Virtus that were not fired. I loaded another 16 Sig BBs into the magazine.

The second target has 9 shots in the target in 2.341-inches between centers. Once again I had to shoot several BBs to get the gun to fire then and the last 4 BBs would not fire from the gun. They fell out when the magazine was removed.

Sig Virtus Sig BB 2
The second target shot with Sig BBs has 9 shots in it. The group measures 2.341-inches between centers.

By adjusting both the Hop Up and the sight setting I confused myself as to what was happening. But that did not deter me from making the same mistake again. This time I adjusted the Romeo5 dot sight down 6 more clicks and the Hop Up up 6 more clicks. Hopefully something would change. I loaded 20 more BBs into the magazine.

The third target shows 9 BBs in 2.095-inches at 10 meters. The group is a little smaller than the others, so I’m thinking the Hop Up is where it needs to be for now. It also dawned on me that I could be here forever if I tried to adjust both the Hop Up and the sight for each BB. So I decided to leave both things as they were for now.

Sig Virtus Sig BB 3
This third target with Sig BBs shows 9 in 2.095-inches at 10 meters.

Once again there were four BBs remaining inside the gun after the gun stopped shooting BBs out. They were outside the magazine but loose in the gun’s receiver. I had intended for each of these three targets to be 10-shot groups, but this BB feeding problem prevented that.

Sig Virtus BBs
After every round of shots there were always 4 Sig BBs left in the gun.

0.20-gram TSD Tactical White BBs

Next I tried shooting 0.20-gram TSD Tactical White BBs. They aren’t called that on the bag they come in, but on the next target I will shoot 0.20-gram TSD Tactical Black BBs, and the color of the BB is the only difference between the two. The wording on both packages is identical. I loaded 20 of them into the magazine.

This time I got 10 shots in a row! Feeding was perfect. Hurrah! These ten went into 1.747-inches at 10 meters, making them considerably more accurate than the Sig BBs. They hit in almost the same place on the target as the Sig BBs. To keep things simple I did not touch either the Hop Up or the dot sight for the remainder of the test.

Sig Virtus TSD White BBs
Now this is a nicer group. Ten TSD 0.20-gram white BBs in 1.747-inches at 10 meters.

To dump the remainder of the BBs (I had loaded 20 BBs because of the previous experience) I fired them into the backstop on Rock and Roll, once the target was taken down. All BBs were expended from the magazine this time!

0.20-gram TSD Tactical Black BBs

Now I loaded some 0.20-gram TSD Tactical Black BBs into the mag. The Hop Up and sight settings remained the same. Ten BBs went into 2.106-inches at 10 meters. Once again, all BBs fed as they should and I dumped the rest Rock and Roll into the backstop after securing the target.

Sig Virtus TSD Black BBs
Ten 0.20-gram TSD Tactical Black BBs went into this 2.106-inch group at 10 meters.

Once again, all BBs fired from the gun without fail. But the White TSD BBs still grouped tighter.

0.20-gram Marui Black BBs

Next up were ten 0.20-gram Marui Black BBs. They made a 2.377-inch group in almost the same place as the other BBs. They also fed perfectly.

Sig Virtus Marui Black BBs
Ten Marui Black BBs made a 2.377-inch group at 10 meters.

0.25-gram Stealth BBs

I had only planned to shoot 0.20-gram BBs today, since there were so many to test. But I had loaded the magazine with 0.25-gram Stealth BBs before realizing what they were. Since they were already loaded, I shot a final target with 10 of them. As expected they landed a little lower on the target than the 0.20-gram BBs. Ten of them landed in a group that measures 2.175-inches between centers. That’s about as good as the worst of the 0.20-gram BBs. I could play with the Hop Up to try to improve the group, but for today I will leave things where they are.

I want to add that this was the only other BB besides the Sig BB that had feeding problems. Several times during the shooting BBs failed to come out of the gun.

0.25-gram Stealth BBs
Ten 0.25-gram Stealth BBs made a 2.175-inch group at 10 meters.

Rock and Roll

As a final test I took the best BB of the test, which was the TSD White BB — and shot 16 into the target on full auto from 10 meters. I fired two bursts, with the last one being the longest. The gun was rested for this target just like it was for all the others and all the BBs fired as they should.

This group is perhaps the most enlightening one of the day, because it represents what the Virtus can do when it’s used in the way it was designed. 16 BBs went into 2.743-inches at 10 meters.

Rock N Roll
Shooting 16 shots full-auto gives a group that measures 2.743-inches between centers.

Discussion

This Virtus is a serious select-fire AEG. I consider the accuracy we have seen so far to be very respectable. And the gun hasn’t been fully tuned or tested. 

Up next will be the heavier BBs that range from just above 0.20-grams up to 0.30-grams. If I find any more 0.20-gram BBs I will also test them as well.

Following that test, I will exchange the 120 mainspring for the lighter 110 spring and completely test the gun again — both for velocity and accuracy.

Summary

Sig’s AEG Virtus is a serious airsoft airgun. They should be proud to carry it in their ProForce line.
