KJW M4 vs WE M4/M16 GBBR?

[LocoYokoPoco]

So I'm interested in purchasing a GBBR this summer (July/August) and I was wondering which one will better suite me?

I'm currently looking at the KJW/Tanio Koba m4 GBBR (Mod to M16 frontset or extend the stock barrel) or the WETT AWSS M16A3 Gen 3 GBBR.

Here is a list of stuff I would really like to have:
-Reliability (10,000 rounds+ a month with moderate maintenance)
-Gas efficiency
-Decent performance in cold temperatures (about 5*C give or take)
-Ease of upgrades, both internal and external
-Easy to maintain
-Really good hop-up (aftermarket included)
-Ability to install an SCS Concave Spacer or something of the like
-Ability to install at least a 6.03 509mm+ tightbore barrel
-Ability to adjust FPS (I know it's available for both platforms, but which one is easier to use?)
-Price is around $400-800 without upgrades (a LITTLE flexible)

So far, I've read countless of positive reviews and feedback of the KJW/TK M4 GBBR and I'm definitely leaning more towards it. The WE GBBRs however, have received quite a mix of reviews and user comments. The WE SCAR GBBRs looks and sound nice, but from the mix of comments I've read, I'm concerned with the reliability of the gun. I would love to get the WE M16 GBBR, but I haven't heard anything about that gun.

With that in mind, I am definitely open to other suggestions of GBBRs. It doesn't have to be limited to an M4/M16 variant. A bulpup GBBR would be the shit, but I doubt I'd be seeing one anytime soon. Also, anyone know if KWA plans to intergrate the NS2/System 7 platform into GBBRs anytime soon?

Any input would be highly appreciated! Thanks everyone

I've seen all of them gamed and the only one I could recommend for performance is the KJW.

Its really gas efficient even with a CQBR barrel. If you ran a longer barrel and adjusted the power down it would be even more efficient.
The couple I've seen could do 2 50rd mags on a single gas charge in 10-15c weather. Both functioned down to 6-7c with little change.

You do have to take the bolt out to do velocity adjustment, I'm not sure how that compares to the WE. The adjustment itself is with shims so it's really consistent at a given temp.

Best recommendation is to read the 9 page thread on the KJW here. There are proponents on both systems (and the WA) but the only person I've known who has owned all 3 is now running only the KJW.

I owned a WE M16A3 and it's by the far the best and most impressive gun I had (personnal opinion here), it look bad ass and is a must for long weapon lover. Exact same reliability as the M4A1. I would by another one if it wasn't of the availabitlity and price of it.

My vote is for WE. On the surface, the KJW is a solid gun. But WE has been around longer, has easier to find parts, and is ultimately cheaper than the KJW.

Prometheus, Nineball all the FF companies will be making aftermarket parts for the KJ shortly

How many rounds have you put through the gun so far?

Wait what? You put 5 grand on the M4 but it's still factory stock?

5 grand... is most likely a strange use of the term referring to round count.

There's reports of the KJ ones going for well over 10,000 rounds before needing maintenance...

and with the 30 round mags that's well over 300 mag changes...

These are pretty awesome guns

5 grand = 5,000 rounds through......not "thought"

*Amos beat me

Hehe, I'd be I would go over 5000 rounds a month at least. When I first got my AEG, I couldn't stop shooting it. Then came my pistol, which I broken within a month, then when the GBBR rolls in...

I haven't owned a WE M4, but I had a WE scar and I fired it ALOT, but the outcome of that is it would never last for more than a week of good plinking before it broke down and I needed to replace another part, with my KJW, you buy the cradle velocity reducer and the piston, get an old tire inner tube to replace broken rubber bands with, and you're set for life

I've owned an AGM M4 (WA based system), a WE M4, a WE SCAR, and a KJW M4. I now only have the KJW M4, the others have all gone to new homes. While the AGM had the most realistic operation, and the WEs had nice bodies with nicely engraved trades, the KJW actually WORKS! No jamming, consistant hop-up and velocity. There aren't many upgrade parts available, but you don't need to upgrade much. This one works, and works properly, right out of the box. A few parts and it goes from great to bulletproof. Get the Cradle Airsoft piston, velocity reducer, and tightbore, and you are set.

KJ for the win. Have owed mine since they first mailed me the first prototype (before actual release date). Very reliable, it just KEEPS WORKING, unlike any of the other brands out there.

Keep in mind that the WE types do not have a real open bolt, while the KJ does.

True.

KJW's blowback is entirely dependent on an elastic band.
