I know grouping shots do not mean a lot compared to actual fielding a weapon but you have to understand I am going to use my rifle for target shooting and not for skirmishes, at least for quite some time.

Also, I've done some at home upgrades to the rifle and I wanted to see if I had actually done more harm than good.

In addition, my sights had to be zeroed in (and that took me A LOT of reading eheh before I could get to know what to do and how).

I am posting this test so that people may look at them and get an idea of how this kind of rifle shoots, compare it to theirs etc. etc.

I am also using this thread as a repository in case I upgrade my rifle and want to compare how the upgrades increased or decreased the overall accuracy. BB weights and brands are also going to be tested some time soon so, this thread might do some higher good than I think :)

Specifications and data

Rifle specs:
- Tanaka M40A1 PCS with unrestricted nozzle
- PCS valve set around 70% (could have been better, sweet spot at around 80%-85%)
- King Arms bipod
- Guarder 3-9x40 Illuminated Scope

Commercial upgrades:
- King Arms reinforced striker spring and steel impact plate

At home upgrades:
- Stronger magazine to bolt valve spring
- Magazine holder shims to crate better magazine-to-bolt seal
- Teflon taped, centered inner barrel
- Reinforced hop up using a square small patch of aluminum adhesive foil

BBs and gas used:
- Madbull 0.40g More info
- HFC Top Gas More info

Weather conditions:
Temperature around 27 degrees
Wind close to zero (hard to see leaves moving in the area)

Phase 1. Zeroing the scope

Here is what I've done. I loaded 10BBs, emptied the gas in the magazine and put it back, holding it for around 4 seconds.

I had NO houp. The wheel was slightly grinding on the plastic dent, slightly enough to predict no hop up was being used.

I placed my target at around 3 meters and sighted the scope. The elevation on my guarder scope is unable to be centered at this distance, meaning I was shooting around 5-6 Mils higher than the point I was aiming to.

What I did, however, was zero the windage to my best and then zero the elevation to around 5 Mils higher than my center. As I said, it is impossible to zero the elevation at 3 meters because the knob locks and cannot go any lower. I suppose this is because the scope is not meant for 3 meters shooting eheh.

I do not know the FPS I am shooting at, but this is the result of my zeroing shooting at 3 meters.



Phase 2. Shooting 10 rounds at 12 meters

I placed a new target at around 12 meters, reloaded gas and BBs and fired 10 shots at it.



This is the picture showing my rifle (far left you can see a red spot, that is approximately the position of my rifle butt) and the target (the white box on the right).



Since my sights did not allow further "lowering", (I guess I am zeroed at around 30 meters..I will have to find out) - I had to aim lower than the point of impact. My aim point was:



Phase 3. The results

4 shots in the center, almost impossible to see one from the other, and 6 around the center, that you can see pretty clearly.



BB strenght at 12 meters:



Short Public Service Announcement

As you noticed, these rifles must be handled and used responsibly at all times. People around you trust your maturity and will hold you in the highest of respects when they will see you handle your weapon responsibly.

When playing with others, always respect the maximum allowed strenght for your country and for the club.

Keep this table handy to remember Minimum Engagement Distances for your weapon.



Printer-Friendly:


Your discipline with the rifle will determine the valor and esteem others have for you. Honor the rifle :)

Thanks guys! I would love to say no fence was harmed during the test but I'd be lying ;)

Now I don't know what I should get first: a co2/hpa kit or a full set of upgrades (tightbore, steel pieces etc. improved hopup etc.)

I think the full set of upgrades could be first because reinforcing the entire action can be a good idea before going for the co2 rig. Also, co2 rigs are darn hard to find here in Italy, I'd need to buy it off someone, even someone willing to build it for me and get paid for it :)

Not only was this a useful thread to read, but just goes to show you shooting people from three feet away can and will do a lot of damage. ;) And that is why we have MEDs.

Nice thread, interesting stuff. The bb marks give the fence some character.

Absolutely. Fuzzywolly you are more than right. While I take my rifle handling discipline with the highest esteem (and never take even the slight risk while using it) I must say I was astonished at what I saw when I removed the paper target and saw how the fence had been smithed.

Even at 12 meters all the BBs penetrated half way (3mm) into the wood. Now, I don't think my skin is harder than wood so I know for sure that is going to hurt.

What Fuzzywolly wrote takes me to post this table, that you guys probably know already, but it is a nice public announcement to make.

Minimum Engagement Distances exist to ensure the safety of all players.

Print this table and learn the basic "limits". Notice the bottom right critical levels that go over the Mil- standard...that means safety glass are going to be punctured/broken..very bad.

More like gets rid of some more character....

(Get it? Cause the B's are tearing holes through the fence and killing it off a bit? Another dry, terrible joke from Daniel here.)

Lol I got it without requiring the explanation. I guess I am right behind you in terms of dry jokes :)

Anyway, it did not get rid of its character: it just moved parts of it half a meter further back, on the ground :)

If you do go with the upgrades, I wouldn't recommend the G&G cocking piece, it is out of spec compared to my Tanaka piece and also a softer metal.
Thank you! I wanted to order the G&G Power Pack but I might just stay away from it..and I was also going to shop for the G&G Rubber set but - if I get the King Arms Chamber Conversion for VSR Barrels..the rubber set is not going to work, I am right?

You will need 1 piece of the set that is used on the bolt.
Sorry I don't understand: the KA Chamber Conversion (has new nozzle in the package) + a VSR barrel combination does not *require* anything else, correct?

Thanks sorry for my lack of comprehension lol

It was bad.....................but not as bad as a fuzzy joke...........just kidding. Not really though.

If any thing that fence was blessed by the pope..

Because its holey...........

And that was attempt at a fuzzy joke..............I feel dirty after using such bad humor.

Latest grouping shots (after all the upgrades)



I think the whole rifle has improved a lot. This particular snapshot was taken while I was re-zeroing my scope. I wanted to try and do all the small little things (breathing control, muscle control, perfecting my supported position etc.) and I must say they really helped! I've always been a little skeptical about these things in airsoft but I must say these were by far tighter groupings than the ones I took while doing a more casual shooting.

Anyway, the rifle has become way more consistent and reliable. What you see above is the most consistent set of 5 shots I was able to get during this scope-zeroing session. I took a total of 20 shots and I must say the others don't differ from this one too much. The above was just impressive since I hit almost the same spot three times in a row.

I am confident that once I get a more instinctive feeling I'll be able to count on this rifle more than I expected!
