Fx Impact M3. 357 issues

I'm new to the pcp game and now I wished I hadn't got into it. My first pcp is a Impact M3 and its had a leak from day one. I called Fx and they sent me a blue back valve for the foster fitting also couple orings. Took a month to get it and still the same leak. Second attempt they send me the foster fitting and told me to reuse the blue valve. Ok that didn't seem right but what do I know I'm new to this. Same leak. Now I'm getting upset I called Fx again and they said they have sent me two parts already now I have to send my gun in. Honestly I'm ready to sell a simple foster fitting for some reason is not sealing and Brandon the tech said oh it could be in your action need to send the gun in. I paid over 3 grand for my setup and been ordering for it every week I'm not sending my gun in and if it hurts fx that much to send me a complete foster fill port that I been offering to pay for since day one they dont need my business and I will be selling this gun its 5 weeks old and had one mag run through it. The only reason I bought the impact was how good they are and how good there customer support is. I really got fooled there!!
 
Please give FX a chance to make this right for you. The FX Impact is an awesome platform, and the FX Impact m3 is the most advanced and best of the various iterations of the Impact. 

Be patient. Once your issues are ironed out, I believe you will be glad you stuck with the Impact.

Not to mention, if you sell a used rifle with a known leak, you will most likely take a loss.
 
Ok I just got off the phone with fx and I guess there was a miscommunication yesterday. I should have known when they wanted to change the action out that I was misunderstood. They are going to email me and she said there shouldn't be a charge but I'm ok paying for it I just want to get it done. I do like the gun and the company that's the reason I bought a fx. I'm sorry to rant but i was curious what other people thought of the situation.
 
Leaking is easy to fix. The hard part is knowing where it is leak and why....but first question is why the heck would a nubie buy a $2200 gun as his first pcp? Its like buying a 50 bmg to your 10 year old son as his first gun. Lol. The impact have like 30+ o rings and many moving parts and is very complex compare to budget pcp. Imo it shouldn't be the first pcp to nubie. There are $300-500 pcp to get into and know how pcp work, how to tune them, how to fix them.. etc.

You said it is the foster male that is leaking. Its very rare to leak in that part for a new gun. I have over 10 pcp for 20 years now and it never leak from there. The only way it would leak there is dirt getting stuck in the one way valve. Which is rare for a new gun. If that is where you think it is leak, just take it the foster apart and clean it. Lub it with silicon oil and reinstall it. Very simple. Not sure why the foster would be giving anyone much trouble. If that's just your problem, can't wait till its something wrong inside the gun and you have to tear the gun apart to fix it lol.
