Xisico 702 PCP Prototype
« on: May 09, 2016, 11:59:12 AM »
I just ordered one.  I really don't need another .177 gun, but I really like the look of it.  Yes, Travis.  I am an air gun addict.  I have already read that some don't care for the look of it, and that's ok too.  Appearance is always in the eye of the beholder.  Now to see how fast Mike gets it to me, and to do the initial impressions of the gun.  I might even do one of those horrible "unboxing" videos where I open it up on camera and say "oooh... aaaaah", but don't actually tell you anything.  LOL. 

Here is what I hope. 

I hope they copied the B-50 valve with some minor improvements. Its got lots of potential.
I hope it has a decent trigger.  ( I don't have a trigger scale, but I know what I like.)
I hope the wood looks ok, but I'm not expecting fine grade furniture for the price. 
I hope the pistol grip feels as good as it looks in the one promo picture they show. 
I half hope its a power house waiting to be unleashed, and I half hope its pretuned with a bell curve. 
I hope the stock barrel is a tack driver.  If its just a quarter thumper well I won't hate it. 
I hope that shroud looking thing has baffles inside.

ADDED May/10/16
I hope it has a foster quick connect for filling.  I really like my Cricket, but I am already tired of worrying about where I left the fill probe. 

I won't tear it down right away, so don't expect to hear about its guts in the first few days after it arrives.  I will tear it down eventually.

Interesting looking guns. From what I can see it looks like they took many styling cues from Steyr. Would like to see more close up pics of it then are currently available on the web.

It shows as "Out for Delivery."  So, are you guys all excited for another cheesy unboxing video.

Now D-boy, speak for yourself. What I want to see, is the results of sighting it in, and 10 shots at 50 yards. Just a video of the unpacking is anti-climatic!

I was joking about the unboxing video.  I hate those. 

So far I have a few mostly subjective observations. 

There was a paper target in the box with the rifle.  It is marked 8 shots, 10 yards, peak wad.  The hole is .485 inches across approximately.  Somebody atleast test fired this gun.  I am guessing it was probably Mike.  I hope the gun can do better.  I'd like to see a group like that at 25. 

The comb is adjustable, but its not something you would want to adjust regularly.  It has plastic nuts (bolt heads maybe) that engage rounds in a slot in the stock.  I can see the slot in the stock getting chipped and worn if you adjusted this very often.  I'll probably adjust it one time when when I put a scope on it, and that will be it.  It won't be a huge thing for me, but for some it could be. 

The plastic Picatinny rail running up the barrel to the muzzle is just decoration.  I suppose you could mount a flashlight on it, but that's about it.  It flexes some. 

Mine came with 3 magazines that hold 8 shots each.  They are internally sprung rotating drums that appear to operate on a similar principle as the Marauder magazines.  You rotate the magazine to load by catching the edge of the drum with your finger tip, and loading pellets thru the single fixed opening.  In that manner they are different than the Maruaders mags.  Time will tell if I like them or not.  I am starting to not like them.  I just loaded one and a half of them, and it was pretty frustrating.  Because they load in the same thru hole as they fire they tend to fall thru or not go in far enough making it hard to advance the cylinder so you can load the next pellet.  This could have an affect on accuracy.  I may make a single shot tray for the gun.  FYI 10.5gr CPDs just barely fit in the magazine.  7.9s might be better, but I wanted to try the size and weight pellets I am likely to be shooting.  No I haven't read the manual yet.  The magazine goes in from the left, and is a very tight friction fit. 

Just tried some 7.9s and they loaded a little easier.  Still needed to use a stylus to push the pellet in gently to get the magazine to rotate so I could load the next pellet.  I don't like the magazines, but atleast it came with three of them.  Hopefully that is something that can be improved before they go to full production.  I think anybody shooting heavy pellets is still going to want a single shot tray.  There just isn't enough room otherwise. 

The gun seems to be mostly right handed.  The bolt might be swappable, but the comb is for a righty.  As is the safety.  The comb itself is ambidextrous, but the knobs used for setting the height might irritate some left handed shooters.  I can shoulder the gun left handed, and it doesn't bother me, but I did just feel one of the knobs touch my cheek.  I suppose with a high set it might not be an issue. 

Speaking of the safety.  Its a bit of a reach with my forefinger to operate the safety.  Its a slide safety on the side of the trigger guard well in front of the trigger.  Its not insurmountable.  I'll learn to use it.  A left handed shooter will have some issues using the safety easily.  You push it forward to the "safe" position, and pull it back to the "fire" position. 

I like the wood.  Its got nice grain to it, and has a fair redish stain and a regular commercial clear coat.  Nothing special there.  It has some pretty grain to it.  I don't know if that is good or bad for a rifle stock, but if it was a coffee table it would be very pretty.  The pistol grip is almost exactly the right size for me.  Maybe the tiniest bit large, but I'll have to get some trigger time in to decide. 

The plastic forearm is ok.  I like the look, and it doesn't feel bad, but I'll have to wait and see. 

I just fired three shots through the gun, and it cycles decently enough.  At first I felt like the bolt might be a bit heavy at the back of the stroke, but I think it was mostly in my head.  The actual firing cycles were smooth. 

The trigger feels nice enough once you remember to disengage the automatic safety.  Probably good enough that I won't mess with it anytime soon. 

The gun is loud.  No part of that fancy rail does anything to act as a moderator or suppressor.  I may remove the rail for that reason alone.  So I can fit a moderator. 

Sorry, no accuracy or power testing so far.  I was busy all day trying to work out a design for a customer, and never opened the box until just a little while ago.  It does have a kind of neat "power" adjuster.  The manual (yes I have read it now) says you can adjust it with a coin.  On the side of the air tube there is an indicator claiming to show the approximate speed range.  Without opening up the gun it looks like it probably adjusts the hammer spring preload.   

I'll probably throw a scope on it and shoot some paper tomorrow.

I like the trigger.  Its got a long first stage, short crisp second.  I don't have a trigger scale, but its just barely heavy enough to be considered a field trigger in my opinion.  I had no issues with it bench shooting. 

Initial accuracy is not great, but its seems to be consistent. 

I shot 21 pellets over the Chrony.  If you recall I fired it three times last night.  Actually it was four.  Once was a dry a fire.  So, I was not starting from a perfectly full fill. 

4 shots not recorded. 

The first 8 were 7.9 gr brown box Crosman Premier Domes. 
1 1037 7.9gr CPD
2  849 (stove pipe) first hint
3 1037
4 1029
5 1022
6 1017
7 1008
8   931  10.5 grain CPD
9   922
10 916
11 908
12 902
13 893
14 891
15 884

16 884
17 876 Shot to group 1" 23 yards
18 876 Shot to group 1" 23 yards
19 869 Shot to group 1" 23 yards
20 851 Shot to group 3" wild drop did not flinch. 

I did shoot the gun off a bench rest (sled) for those grouping shots, but I only had a little 4x rimfire scope to spare.  Its also possible the gun doesn't like CPD 10.5s at that speed.  Once I get the desired power tune figured out I'll shoot various pellets and see what it likes.  I am hoping it likes 16gr rabbit magnums.  I am kinda thinking that's going to be my target tune weight to around 900FPS.  ~~~ One more comment to give the gun a bit of a break.  Its a little windy here today.  It was not a fair accuracy test. ~~~

It appears to be like many Chinese imports.  Tuned to a fairly high power string with no curve.  To be fair there were four discharges last night that were not recorded so there is always the chance it has a tiny curve at the top.  I doubt it, but I'll shoot a new string tomorrow after I refill the gun just to see. 

All I did to prep the gun for shooting was run a dozen patches down the barrel to remove crud.  There seemed to be a fair amount.  The power adjuster was left just the way it was when it came out of the box.  The same as in the picture I posted last night. 

As you can see when I stove piped two 7.9s on shot two the gun has the power to shoot some heavy pellets.  I might try a short string of 16 gr rabbit magnums in it at some point. 

At shot 8 (or 12 if you count the unrecorded shots) when I start shooting 10.5s the velocity backs up the conclusion indication from stove pipe on shot 2 (6).  This gun can deliver some heavy pellets if tuned for it. 

Right now the shot count is pretty low in my opinion, and the gun is pretty loud.  I think I can get a lot more shots out of it, with a curve and decent power.  I may open this gun up to look inside sooner than I originally planned.  I do think its got the potential to be a pretty good .22.  The manual indicates they plan to make a .177 and a .22 version.  Mike said they are also considering a .25. 

The way the gun is now I don't think it would take much to tune it for a solid power and shot count in .22.  Not having looked inside yet I don't know how much would be required to make a solid .25 out of it. 

I had a laundry list of little improvements I sent to Mike, and he let me know the factory is already changing the magazines.

After one day and a few shots I can see me owning more than one of these.  If I figure out (with help I hope) a good tune for it, I can even see them becoming gift guns.  I can even see doing a bottle conversion on one at some point.

One last comment.  It has a gage.  Accuracy is unknown.  I'll check it against my air tank gages when I fill it. 

The gage is marked in MPa.  Now I am used to PSI, and I've gotten used to BAR, but now I have got to go look up MPa.

I just filled the gun.  I wasn't watching the gage when the valve clicked open so I can't give any air useage data. 

3000 PSI on the oil filled gage on my Tiger Shark tank is a little over 20 MPa on the gun gage.  20 MPa is about 2900 PSI, so that seems pretty good. 

I think my previous shooting data may be totally worthless except to show this is a powerful gun.  When the gun arrived it was filled to the edge of the green on its gage.  The edge of the green is 15MPa.  15 MPa is about 2100 PSI. 

I'll have to start all over with my data collection.  Light levels have dropped a little.  We have a storm to the north.  I don't know if I'll get any good Pro Chrono data or not, but I intend to try.  If not there is always tomorrow.

Anway, I feel silly.  There are around 16 shots above where I started the first time.

The accuracy may be better than I originally thought, or the barrel may be starting to shoot in.  I noticed when I took the time to get just right on the scope my shots dropped on target better.  That's actually kind of hard to do on the bench.  My gut gets in the way. 

When I had a short break in the wind at my stock 23 yard target I shot five in under 1/2 inch. 

I definitely need a better quality scope on this gun.  I don't think it will meet the 5 shots at 50 challenge, but it might be better than I first thought.
