A&K M4 CQB (SOLD)

5 posts in this topic

Putting this back up for sale as unfortunately, the previous buyer was unable to.

 

I have an A&K M4 CQB-R (this one) but as the wires were getting ruined by the adjustable stock, it's re-wired to the front (large Tamiya) and I have replaced the RIS handguards with standard ones capable of holding an 8.4v battery.

The rear sight has been replaced with a metal M4/M16 carry handle as I want the CQB style rear sight.

The gun is full metal (excluding pistol grip, handguard and stock), the receiver has white trademarks (shown in last picture).

 

The gearbox has an issue, but I have no idea what causes it - I'm pretty certain it's an easy fix.

It will lock seemingly randomly when firing, sometimes it will last a whole day, others it won't last 20 minutes before it locks.

I think it may be an issue with batteries because after it locks, if I change the battery it works perfectly. It seems as if the battery isn't providing enough power. I have always used an 1100 or 1600mAh 8.4v battery.

I'm useless when it comes to gearboxes and I don't fancy paying someone to look at it for me, so this is the main reason I'm selling.

 

I have also replaced the nub in the hop unit with a MadBull X-type one because I managed to lose the stock one. It works well and gives better consistency than before.

 

Other than above, the gun is completely stock, has a 285mm inner barrel, metal hop unit, the stock gearbox and comes with a 300 round hi-cap magazine. I got it as Christmas present last year, so is almost a year old but has been cleaned regularly.

 

The gun has a metal body, barrel and sights, the stock, handguard and pistol grip are good quality plastic, none of that cheap shiny crap.

The magazine and end of the barrel near the sight are pretty scratched but it can be solved quite easily by a nice can of spray paint .

 

Here's a quick run down following the template provided;

Make: A&K

Gun/Model: M4 CQB-R (RIS and rear sight replaced)

Accessories: 1x 300round metal hicap magazine, original box and documentation.

Condition: Externally good, used. Internally, gearbox locks - an easy fix for someone who knows what they're doing.

FPS: 280 last chrono, but hop was broken and stuck on maximum (fixed now). It was 336 FPS new, XSite lowered it from 542 FPS before sending out to me.

Splits/Swaps/Part Exchange: No/No/No

Price/Payment: offer.

Much overdue bump, I'm also now in the process of attempting to fix the gearbox problem.

I'll bump again once I've tested it properly and post results/condition of gun after.
