Springfield conversion

Postby Lord Elpus » Sun Nov 26, 2017 3:29 pm

The last few weeks I've been trying to get a Cyma 702 sniper converted to a Springfield 1903, early version finished, to use on the 17th Dec.
I'll try and post a pic, getting close to finished now, not a carbon copy as the 702 (same as Snow Wolf M24)is a bit large round the hop unit area but quite close.

Just have to finish ladder sights, and make sling mounts, get rid of telescopic mount, the hopefully done, quite accurate, and has a very good range.

Nice, is that an original stock or did you carve it yourself ? :)

Cut from two pieces of 18 mm softwood, glued with pva, then planted two 10 mm pieces of pine to sides.

I guess about 50 hours, so far. I thought I would try softwood as it was to hand, no cost! Didn't want to ruin a decent piece of wood. I'm surprised myself how well it works with softwood, plus it will get "battle worn" quicker!

Hi will you be able to use the original mag catch ,i used the metal housing block( screwed to the bottom of the hop unit and barrel)
It was mostly un modified,i just made a new catch and spring,out of metal when i did my K98/VSR.

One of the bonuses with the 702, as opposed to the vsr model(701), is the mag housing is integral,just screws on the bottom of the barrel, already boxed, that's on of the reasons to make the stock, make the wood fit the mag " box" as I think using an original stock, it would be a protruding problem!
Apart from cost of getting an original Springfield stock, it would then have to have a different mag feed system to look any good.

Hi my cyma m701/98k needed a maple leaf hop rubber to even shoot properly the stock rubber was so hard when cold fps could drop by about 150fps,the hop arm has a lot of side to side play(0.5mm)so some baked bean can shims will help there too.I downgraded mine to 1 joule,it wont lift bb's over 0.25 so its seems pointless being 470 fps ,its much better and safer downgraded and you can engage from any distance.
in fact it can't over hop a 0.25 bb,but i have not tried filling in the gap bettween the 2 prongs on the hop arm yet is a slow burn project,tear it down and improve a couple of things and test,its a never ending process realy.
if you get a downgradeto a different spring and it shoots a bit low ,a 60mm spacer behind the spring seems to add about 50fps if that info helps.

Thanks,
I have already upgraded to a steel cylinder, metal composite piston, running about 480fps, has a maple hop rubber and delta nub. It's not bad at all, does 70 metres, using .30's-32s. Have got Airsoft pro hop unit for it.......but have put it somewhere safe......and forgotten where that is for the moment!
Already done the shim bit on original hop, only the odd low right shot, the rest, quite accurate. I will buy a tight bore barrel for it soon "crazy jet". Have fitted some to customers pistols, work very well with all the other upgrades, and now they do long barrel versions.
The only real down side to this 702, it does have a tendency to miss feed every now and then, jams cylinder, release mag , bb drops out, and away we go again, as long as you don't force the bolt/ cylinder and not crush the bb, works on. Crush the bb, spend time picking all the bits out!
Andy.
