Krytac SPR MK2 low FPS

[GenePoolReject]

As someone who is relatively new to air soft I am seeking advice from some of the more knowledgeable folk around here. I have a Krytac SPR that is a tad underpowered. It’s currently rocking 240fps with .25’s (so around 260 with .20’s?) and I’m after some advice as to the possible cause and perhaps even recommended parts to change.

I don’t seem to have any real issues on the field, despite the low FPS it still out performs my buddies upgraded TM Scar but I can only imagine how good it could be if I got it up to my site limit of 370!

 

All help is very much appreciated, thanks in advance.

Look up Air seal mods, and spring upgrade. I wouldn’t change the spring till you have checked the air seal. 

 

The reason yours shoots well is the hop and how it’s set up. 

 

I had a 210fps gun that could get to 50M accurate as anything,it just took a week to get there.

I suppose I could do with opening the gearbox to try and figure out where I am loosing compression. It’s a relatively new gun and has never fired at the rate it should do out of the box, I would of sent it back if it wasn’t for the unique way in which I acquired it.

 

I’m slightly concerned about taking it apart and then not getting it back together again.

Then can I suggest you send it to a tech to service it. You can talk to them about what you’d like etc.

 

Then I’d suggest you buy a dirt cheap gun/gearbox and take it apart and put it back together so you understand what makes your gun tick.
