Godnoes where to start, but to save time; Yes, it is a phenomenal gun for a discounted First-hand GBB SMG, Yes it does have it's current issues which i'll need some guidance with and Yes I may have a match coming up soon, and my birthday falls on the 24th which also gives me a £50 spending leeway, which is more than likely going to toward attachments and gas for my mp7. Onto the first order of buisness...... Got myself the Navy version; extra rail on the bottom, giving me more customisation ISSUES A few months back I had an issue with my MP7 concerning the bolt release. that has now been fixed, but now more issues have risen. To start, the bolt will occassionally lock back when the charging handle is pulled, and when the release is pressed, the bolt will move half an inch forward and stay there, giving me 5 mins to pull the handle and release until its back to normal. At one point, the bolt was even jammed when i attempted the first pull of the charging handle! As a beginner airsoft, this worries me, but not as much as the next issue. Double feeding and/or not firing. However, Double feeding was a past issue, because now its along the lines of quadruple feeding and puking BB's all over the bolt and chamber. for the technicals, I use 0.20 gram BB's and Green gas(See attachments for specific gas used), have disassembled it ONCE and that's when the problems appeared. Here's the type of green gas that I used prior to the issues, if it helps. My only thoughts on fixing bolt issue is A) Invest in a low-power CQB bolt ASAP. B.)Oil up the bolt linings to ensure it's running smoothly C) Disassemble the gun again and double-check everything's where it should be. As for the quadruple feed; A) Invest in another magazine B.) Assume the magazine spring and/or feeding lip is damaged, creating eiter a bigger feed hole in the mag or is pushing bb's up too fast, and attempt to find a fix for these issues. C.) Bucking has swelled within the gun and needs to be replaced. Hopefully someone can help and is an experienced airsoft engineer Moving onto my favourite topic...... ATTACHMENTS
As mentioned above, a low-power bolt is on my priority list, but im unsure where i can buy one as i'd rather not fork out more than £20-25 for one overseas, that's if the rumours of KWA discontinuing the MP7 are true. Even then, I've heard mixed reviews on the NPAS valve kit, so im skeptical on that. Here's my baby in it's glory along with the G18C. Pretty sexy with it's attachments, but i feel that it could do with more. Naturally, im stuck with choosing a specific type of laser, so im tempted to get a green PEQ-15 laser replica; their big but not clunky, remain flat and parallel to the gun and gives me more of a meaner look, in my personal opinion. I'm also thinking of getting a flashlight, possibly a QD suppressor.....or a tank buster barrel, which will need a 16mm to 14mm adapter, to my knowledge.
Overall, opinions will be most appreciated, and personal reviews and pictures will be even more TL;DR - Bolt's jamming and double feeding, need fixes. recommended attachments also requested.
