Fjs m4 cqbr block 1 review

Hello , Its my first topic and the gel blaster hasn’t arrived yet , but when i receive it in sunday , i’ma do an exact review of it . now everything i say is only based on the box , the test and other things
( some sellers make these come fully loaded with toy accessories , so that’s a positive point , here )


the box says its a v2( jinboo edition ) tan color , this means this gun will have blowback , some metal parts and bolt catch function

looking at the manual the certificate shows its made by feng jia sheng ( fjs ) at shantou factory , idk what other brands are made at that factory but looks good
now lets go on to the blaster itself

this is it’s bolt catch and blowback , this blowback and bolt catch are metal , trigger is metal , selector switch and other parts may be but not the buffer tube ( i’ma change the mag to a metal one , the buffer tube is also going to get changed like that )

the thing that i like is that the selector is like the real thing , it rotates on both sides

so this means this gearbox is the same as fjs blp , good thing i could say , now the fps wise this is like the thing its based ( cyma m4 ) and inspired so you expect 240 to 260 fps outa the box but it’s going to get consistent when you add a green o-ring , a m95 and other things to this ( cause the gearbox has a metal spring guide , you could go up to m95 without any issues when perfectly shim-ed
I will continue this topic when i get the blaster in my hands ( that was just the seller sending my blaster’s images , so i could show it to you guys )

first upgrade on this thing is going to be an integrated hopup ( easy cause i sand a bit of the barrel then take an integrated barrel hop from the tg arp9 ( parts are hardly available so last ditch ) then those upgrades make this thing stable
update ( i can 3d print hops , so this won’t be that necessary )

Now , my blasters came ( they came last night ) and i’ve runned about 3 to 4 mags through each this morning
Could say m4’s really solid but won’t work good enough with blue gel balls and also
the bolt catch pin is weak ( the bolt catch moved outa it’s place from the recoil of the blowback lmao , just pushed the pin firmly in , after reattaching the bolt catch button )

so i decided to mix the gel balls ( extra hards , decents and cheap blues ) to make the performance better cause the bohan slr likes those but this doesn’t likes them
the fjs m4 is solid , has a good blowback system with high recoil than some other blasters i had ( even the slr and could compete with atm a bit ) but i recommend to put on bolt catch mode so the blowback is disabled
the gun’s external quality is great , and the internals but it only feeds with gen 8/9/10 mags ( i’ve bought the slr coz i thought the metal mag works on this one , but it doesn’t only gen8/9/10 magazines work i guess )
