I charge my Titan Li-Ion batteries with the same charger I use for my LiPos (Accucell S60). They're all basically the same chemistry at the end of the day, the bit that is a touch confusing is that when you get a Titan battery it has "CHARGE ONLY" on a label on the balance lead and "DISCHARGE ONLY" on a label on the main power connector. Thing is that my charger won't balance charge unless BOTH are connected. Hasn't burnt the house down yet though.

V3 won't fit in there.

As mentioned, ideally they should be put to a storage level but it isn't absolutely necessary. If you don't have a decent charger, get one.

Might be worth having a watch of this before you go headlong into your DMR build

If they're the Warrior pouches with the black, textured vinyl type lining, just ditch the bungee loops and run them as is. They'll be fine. Alternatively, get yourself some kydex inserts and shove them in your pouches. Job done.

These are worth a look https://www.wtfidea.com/air-tank-pouches/ In case you don't know them, WTF grew out of the paintball world into general tactical gear via airsoft so they know what they're doing. It's good gear, shipping from the US is pretty quick and not too expensive. Tactical Kit stock some of the more tacticool pieces they do but not the paintball/airsoft stuff.

I like M4s too (I have three). I just like baiting people that get upset when you dare suggest that their L119A2 is just an M4 in a fancy frock. Yours is very nice though (but if you do have a Bazooka that would be SO MUCH COOLER!!!!!)

Except you can't, because the Magnus effect in the case of airsoft BB's provides lift. It also produces increased turbulence in the BB's wake which contributes to drag which affects the terminal energy. Axial spin in rifled barrels increases range by the conservation of angular momentum which is a whole different kettle of ballistic fish.

Cheap as chips floor mats. Check your local DIY store for deals on multipacks of it. Just use the "back" side outwards (a lot of it will have diamond plate patterns embossed on).

I'm intrigued as to how that guys gun actually performs normally. I find that the 7.4v Titans I use work comparably to every other 7.4v LiPo I've used in the past. So far they've been in two of my M14s, my MK12 DMR (420FPS with an M120 spring) and my old G&G SCAR L. No problems with rate of fire or trigger response on any of them!

Nice M4.

Very little I should imagine. The "soldered together cans" is why the Titans only come in a few different form factors of course. I have four of them now but they've not been on the market quite long enough for personal experience of their claimed longevity but all I've done with them so far is charge them, use them and then chuck them in my kitbag (in a LiPo Safe bag - I'm not THAT mental).

My Allwin DCU G3 set has FINALLY arrived from Royal Tiger after 4 months (nothing to do with UPS mind). No pics yet as it's still in the bags but it looks GLORIOUS!

They're metal cased (effectively 18650 type cells joined together) so it's highly unlikely but never say never!

Lithium batteries - FAQ https://www.batterypowertips.com/difference-between-lithium-ion-lithium-polymer-batteries-faq/ I've been using Titan Power Li-Ion batteries for a while and there's some pro's and con's. Yes they last well, they have plenty of power and they don't puff up. They also hold their charge really well once they've been charged. However they do only come in a few form factors and sizes are limited by the construction.

Drop this guy a message on ebay https://www.ebay.co.uk/itm/294273163040?var=592925401510 I bought a couple of his - one for a contour camera and one for an M2 and they're really rather good. He does a custom size option if you tell him what you want!

They come with 1" adapter collars.

Talking of the other bits, I have a spare set of Vector Optics High scope rings that I don't need. I'm sure I could let them go for a reasonable price. https://www.vector-air.co.uk/product-page/vector-optics-30mm-picatinny-ris-high-scope-mounts-scot-54h these ones. £10 posted for you, brand new in the box and everything.

There's a good reason for that...

Be interesting to see what the differences are on the Warhead BASE vs an Infinity CNC. The price difference is down to £20 and the performance is (in theory at least) less than the standard motor.

Real ones are made of 7075 aluminium anyway so I don't see any reason why the airsoft ones would be made of steel. There are some CNC billet receivers but they're definitely in the top end like Inokatsu, HAO etc

To kick things off, given that we have established your budget already as far as QD mounts goes...none. You already have several on the gun itself. The round sockets on the lower tips of the stock, the front end of the stock, either side of the receiver rear plate and the back end of the handguard? Yeah, they're all QD sling points. Slings - something like this will be fine https://www.ant-supplies.uk/gun-slings/qd-push-button-swivel-slings.html It's a knock off of a Magpul MS something or other with QD ends and a convertible single - two point buckle jobber. Cheap as chips and they're readily available in most airsoft stores between £10-15 or from Aliexpress for less than the price of a chippy tea!

Yes, most "metal" airsoft guns are cast alloy of varying degrees of shite. That said, I've had plenty of cheap metal guns over the years that have been absolutely fine. As long as they're not damp and the finish is intact there's no reason they would corrode and I don't know of any that have just spontaneously bent or cracked unless they were stored VERY badly. In terms of the specific guns you've mentioned they tend towards the better end of the spectrum in terms of fit and finish so you'd be starting off at a better place. Given the use of "dollars" I'm going to assume you're in the US so unless you're happy to skirt the law or just pay the tax stamps for an SBR then a true MK18 is going to be tricky thanks to the whole 10.3" barrel and full auto trigger group (although I'm sure there's ways around it because "muh freedums") but we can only really give you advice on airsoft stuff. As for spending a "few more dollars", I think ou'd need to add a couple of zeroes to your budget to get those as real firearms over airsoft replicas!

All sorted! Sent him a message on FB.
