Guys, if you have an issue with a price on any classifieds ads, then the place to discuss it is Macks, not pissing all over the ad itself, as per the classifieds rules.
In particular, @CrackPipeCallout, you've been here two hours, & done nothing but troll 2 ads, given your username & if trolling is your thing, this may not be the best place for you.
You're gonna be sat on this for a long time at that ambitious price.
Sticking some attachments on a RIF and replacing some of the easier to replace internals does not a build make, especially when you're leaving two of the biggest weaknesses of the platform to chance still in the form of some internals for the sleepy trigger and the standard backplate that is known to break.
Marui MP7 - £300 retail
Metal front rail kit - £15 I've seen these for
Angled grip - from a fiver to £35 depending on what brand it is
Laylax (nineball) 6.00 power up barrel - Shit barrel
Maple leaf autobot 60° bucking - Shit rubber
Steel sear *unfitted - Fit the damn thing
Pro arms 130% hammer spring *unfitted - You don't want to increase hammer tension as it's gonna ruin gas efficiency
Guarder enhanced nozzle - £30
Pro arms 130% nozzle spring - Tenner
Racegun steel Surefire muzzle brake - ??? If you think it has value take it off and sell it separately, or expect to pay 50% or less of retail when bundled in on a RIF
Racegun steel Socom46 silencer - As above
VG6 offset mount - As above
Short stroke buffered - Ahh yes because I love further ruining gas efficiency, increasing the likelihood of missfeeds and/or nozzle damage
Lightly polished bolt - Pics? Because judging by the rest of your 'build' you've done a ham fisted job of this and you'll have introduced more issues than you've 'solved'.
ModLite OKW version high power search beam light (powerful) - Ooo, powerful, expect a chunk off retail on this when chucked in with a RIF, if you want anywhere near close to retail, sell it separately.
Dual switch (DBAL / light) - Well done
Blue laser DBAL (too powerful for games) - Don't put it on an airsoft gun then ???
Unity riser - Sell it separate if you want anywhere near value.
Romeo6T multi reticle optic with flip caps (Evo gear high quality clone) - Ahh yes, Evo Gear, well known for their spotty QC, you're probably expecting 'UK Retail' for this rather than £90 or so you can get them from ali for lmao
Daniel Defence swivel mount for sling - ??? If you think it has value take it off and sell it separately, or expect to pay 50% or less of retail when bundled in on a RIF
4x mags (1 permatex gasket sealed mag) - Well done you're selling 3 mags and one boneyard one you haven't fixed properly.
14mm CCW threads adapter (any tracer or silencer etc) - ??? If you think it has value take it off and sell it separately, or expect to pay 50% or less of retail when bundled in on a RIF
Even being generous and valuing the MP7 at 70% retail, your various attachments at retail with no money off, the 'upgrades' at retail with no money off and all four mags at retail - despite one of them being boneyard in reality - you're at £478 minus the various attachments that are an unknown quantity/of unknown value.
You might wanna think about why stuff you're listing keeps failing to sell through, hint, it's your crackpipe pricing, £265 for a £150 USP with a £20 Surefire on it is a particular highlight.
Especially considering the amount of money you want, do you not think you should provide more than just one photo after you had disclosed
There are engravings on the lower receiver?
There is some exterior damage?
