Hello,
I have a Krytac SPR Trident MK2 stock replica, I would like to mount a M130 arc and I would like to know if the internal stock items resist without changing anything.
Thank you.

the stock internals can run a m130 spring just fine.

Can you let me/us know the FPS and what exact spring and bb weight you put in the SPR Trident MK2 when and if you do the mod? Thanks in advance.

I usually use bb 0.25, with bb 0.20 I had 119 m/s. We have not changed anything inside the replica. The spring is the M120, just like it was in the box. It is a precise reply, but I would like spring spring M130 to gain a few miles in the distance without changing anything in the gearbox.
Thank you for answer.

I think the easier question is to address what kind of performance you are hoping to achieve.

The spring will raise your FPS and get a little range. Range and accuracy comes mostly from the hop up and the barrel. A flat hop or r hop will get you extra range and accuracy.

I installed an M130 in both of my Trident MK2 CRB and SPR but had to cut a few coils to meet my field FPS regulation. I bought two R-HOP kits off ebay, search for "RHOP for Krytac CRB SPR Stock 6.05" by a seller that goes by "elvishtac". I don't want to sound like a shill but that's what I am using with excellent results, shooting .36g bb's 225+ feet accurately.

I am assuming you have the US version, so my question is why get the m130 spring if most field limits are 400 and the stock m120 shoots 400, and shaving an m130 basically makes it a m120-m125. For the r hop gun gamers on yt has a vid and an rhop with a krytac barrel will get you around 250ft max range and the stock krytac hopup gets 225ft. If you want the best accuracy and range you should pair the rhop with a tightbore barrel, but it really is not needed because the krytac barrel is already a 6.05. if you know how to make a r hop, great go ahead and do it, if not see if a local tech can do one for you or order a drop in rhop kit.

Yes I do have the US version. My field is wooded outdoor play and has a higher FPS/Joule limit than other fields (1.86J = 400fps with .25s) so I wanted to fine-tune my FPS performance to meet the field limit with .36g BBs. Chopping an M130 spring does not make it an m120-125 I don't know why you would think that? I guess you actually have to have some experience doing it to understand.

I van vouch that the RHOP kit I bought is a good improvement over stock. I played a whole season with a stock Krytac MK2 SPR before making the aforementioned mods. The RHOP kit gives my .36g BBs better spin/lift/distance than stock. Don't get me wrong, I think a stock Krytac is amazing but some of my tuning as made it better for my particular gameplay.

Here's my chrono reading for reference:

I mounted a M130 and after about 50 strokes I felt the engine warmed up. I mention that I use a 7.4 l Lipo battery. When I wanted to disconnect the battery I noticed that the cables were hot. During the shooting the noise was stronger and different. I hope I do not damage my replica.

I converted to deans style connectors to better handle the added resistance/heat, and I also use 11.1v LiPo and just bought a 11.1v Li-Ion (https://www.evike.com/products/86339/ [wink] and have had no issues so far with 2000+ test BBs.

Yes your shooting noise will sound different because it's shooting harder now. If your gearbox is used and hasn't been serviced yet I suggest you open it up and clean/ re-grease the gears and piston rails with something like Super Lube, and your piston oring and chamber with silicone oil (https://www.evike.com/products/44392/ [wink]. There's a few really good YouTube videos on how to get into the gearbox:
