And also for bbu, will kjw kp-06's bbu fit SD hicapa slide. If anyone ever experience this and able to answer, please do.
Btw bbu = blowback unit/blowback housing

MEU BBU has a notch cut on the top (beside the screw hole) to allow fitment of the rear sight. Beyond that, everything else is the same, and for all intents and purposes, an MEU BBU *can* fit in to a Hi-Capa slide. The only problem with doing that, is that you run a very very high risk of damaging the nozzle return spring this way, as it's known to catch on that notch if the sight is not in there to block it.

Would be grateful for any helpful advice!
I have Tokyo Marui Hi-capa XTREME (Full auto) and have already made some modifications to get greater velocity:
- PDI Winter piston head;
- PDI 6.01 precision inner barrel;
Now I have 265-280 FPS on 0.25 BB with Green Gas and 25C temp.
And intend to upgrade the pistol with:
- Guarder Enhanced Loading Muzzle for Hi-capa 5.1 (have it);
- Guarder High Output Valve For Marui Hi-Capa (have it);
- Guarder 150% both recoil and hammer springs (have it);
- Any aluminium slide, that is durable and consistent with my pistol.
I have already tried to combine PDI Winter piston head and PDI Winter piston head but the piston seems to be too tightly moving inside the muzzle - the top BBU spring's power is not enought to move muzzle back (i tested it in my hends, not shooting).
1.Will I win any FPS replacing stock loading muzzle with Guarder Enhanced one? Does it make sense taking into account "tightness" problems with PDI piston?
2. How much FPS may I win after 2nd (intended) stage upgrade?
3. Do TM Hi-capa 4.3 aluminium slides fit to my pistol (exactly slides, not BBUs)? What slide would you recommend?
4. Is it safe to use stock plastic slide with items from 2nd (intended) stage upgrade installed? |
1. No velocity improvement with nozzles. They are for durability only.
2. Each setup is different. Hard to say how much improvement. I would guess 15-25fps improvement, because of the output valve. Will also depend on specifically which one you got. Guarder has two available. Note: You will get drastically reduced gas efficiency. Gas usage jumps up dramatically due to the harder springs and heavier slide.
3. Regular Hi-Capa 4.3 slides will fit. I recommend ILLusion Kinetics slides. Seems like an obvious answer when you ask it in this thread...
4. Yes, it's safe to use plastic slide. you will get best performance with the stock slide.
