Gerkahn Posted June 10, 2010 Report Share Posted June 10, 2010 Does anybody know if there are any coming out for the five seven, or perhaps it uses the same spring as the marui glocks? mine consistently fails to depress the valve hard enough on the first few shots of either a full or rested mag, seems to need the gas cooling to get crisp blowback. If there arent any hammer springs i can use, are there other options? cheers in advance Link to post Share on other sites
Firefly0 Posted June 11, 2010 Report Share Posted June 11, 2010 RCC sells a set with 70% and 130% hammer springs for the TM 5-7. Link to post Share on other sites
Gerkahn Posted June 11, 2010 Author Report Share Posted June 11, 2010 your my hero, ive googled it countless times, have no idea how i missed it. cheers *edit* You don't have a link do you? Link to post Share on other sites
Firefly0 Posted June 11, 2010 Report Share Posted June 11, 2010 I just went to check airsoft stores and i don't find it either :/ I see recoil springs only, which is weird as RCC always have been made both hammer and recoil springs for each gun, sorry. Maybe its possible that Glock springs will work as you said, give me the 5-7 hammer spring measurements and i will compare them to the G26/G17 hammer srpings. Link to post Share on other sites

If there arent any hammer springs i can use, are there other options? cheers in advance This happens with my FiveseveN!!!! I was wondering what was causing this. Upgraded hammer springs will solve this??? I've invested in a SERPA drop-leg holster, tightbore, and extra mag so i want to keep this gun in my kit!!! I love my fiveseven and the blowback is GREAT when it works properly. Would you keep us posted??? What store is RCC?? Do you have a link? Link to post Share on other sites
jotohomomoto Posted June 14, 2010 Report Share Posted June 14, 2010 I field stripped my 5-7 this morning and noticed that the nozzle was getting stuck in the barrel where the hop-up is. I'm pretty sure thats whats causing the sluggish cycling in the first couple of shots. Perhaps if I sand the nozzle, lube and clean it the problem will go away. I will post results or start a new thread if this one is dead. Link to post Share on other sites
Badger Posted August 20, 2010 Report Share Posted August 20, 2010 Could also be the nozzle return spring (part fn-12 in the exploded diagram) is shot. MAG sell a replacement set. Link to post Share on other sites
