Dboys Kar89k conversion, which internals?

[sekkiww2]

Hello fellow ww airsofters!

I have thought about making this kar98k conversion project, but got stuck up on which internals from others guns, like Bar-01, VSR-10 and so on?

Thanks on advance!

JG Bar-10 internals are 100% compatible with those of TM VSR-10s; either of those are solid bases. With AGM or other model VSR-10 clones, you run the risk of having upgrade/replacement parts not fit though

So a VSR-10 base is the best bet, and then of course some upgrades to the internal parts, which have to be modified to fix the kar98k stock.

There are a huge selection of Marui VSR clones (easily a dozen offerings). Some are better than others. The ONLY one that I have found is 100% compatible with all the available upgrade and repair parts is the JG BAR 10. There are others that are also very good guns for a little less money but the BAR 10 is the confident recommendation.

Even with the BAR 10 the weak point is the trigger seer so expect at some point to have to replace it. There are many upgrades for this available. I used to just start out with that upgrade but now just go with the stock part until it fails. (Sometimes it doesn't!)

The AGM 001 VSR is a bit smaller through the receiver group which makes it more compatible for some conversions and all of these clone VSR bolt actions are hard shooters right out of the box. Upgrades refine their precision but add up to big $$$$$s pretty quickly. The AGM001 and other VSRs are frequently half the price of a BAR 10 but understand that the trigger box that will quickly need replacing will burn that savings typically within 500 rounds.

Good luck. It's a fun project and lots of tutorials and support threads here.

Having some friends who are into bolt action ww2 airsoft rifles,i noticed a cyma vsr10 rifle (based on a 
Remington design,can't remember the model number) it was priced at only $65 on Tiger111.
i was surprised how cheap it was , is that one of the good clones and how do they compare to the TM's.

Remington M700, I think. I've got one waiting to be converted some day. I'm not so sure about it, because the trigger box itself is plastic instead of metal.

The Marui is the grandfather of all the Chinese clones which to varying degrees reverse engineered it's design. The Marui VSR is extremely high quality but it's price reflects that. Also be aware the Marui is Japanese company and their products are first and foremost produced for Japanese domestic use. Japan has very stringent FPS restrictions so in stock form (compared to their Chinese clones) they have very low energy springs. Once upgraded they are fabulous but given their initially higher price and then the cost of upgrades a field able Marui airsoft gun is extremely costly.

Advertised FPS (feet per second) can be very misleading and are seldom very accurate so be careful. Most reflect FPS with .12 gram Bbs which are simply too light weight to handle even light winds and remain accurate, lose their enertia very quickly (hence provide less range) and are harder to feel when struck by them. .25 gram should be the established norm as for most decent airsoft guns it's the most effective BB weight. As BBs get heavier the initial FPS goes down (there are some notable exceptions to this statement) but heavier BBs (to a point) maintain their enertia longer and are less impacted by light brush or cross winds.

For significantly upgraded airsoft rifles heavier and heavier BBs can be used but note that with this added weight comes additional destructive power so be sure whatever you field falls within your events safety standards which almost always are based on a .20 gram standard. When considering an unfamiliar weapon or brand I like to view video demonstrations showing actual chrono results.
