"the tolerances are much tighter, the magwell holds mags snug, the holes for the pins are quite tight! Steel bolt fits just fine.
there is no receiver wobble :D
Markings look clean

No complaints.

"Attention for We Tech GBBR owners (from experience transferring parts from WE-888 model) BE PREPARED TO TINKER!

I'd like to first start off by saying this piece is a very well made accessory for the gbbr. It feels high quality and the two halves fit together well. Now for the reason why I am choosing to give this product 3 stars.

I was transferring the parts from my WE Tech 888 model GBBR, and found that the oem parts do not fit. This is not a drop in oem receiver, at least in my case. As far as I know the we tech 888 and m4 use the same internal system.

I needed to file for hours on the trigger box area, trigger pins, mag release, fire select, etc. Pretty much every hole that needed a pin (including the screw port for the trigger box screw) had to be filed down. The only pins that fit w/o the need for filing were the bolt catch and dust cover pins.

Overall I do recommend this to anyone that wants a forged receiver we tech system and is willing to put in the work to make it work.

For others who want a realistic feeling replica and just need something with no hassle, save up for vipertech or tm mws with upgrades.

"Its Ok. But for what you're potentially shelling out, this is just depressing. It seems that the dimension are a bit off to that of a typical we tech body, even after greasing up the trigger box to try to slide it in, there was alot of resistance to the point that i had to use a punch and hammer to get it to set properly and to adjust it to put in the retention pin for the trigger. thats just for the lower.
The upper seems to be significantly smaller diameter for the bolt to fit, if youre using the ratech cnc bolt you dont even need to lube and it goes in fine, but the we tech even greased had a a good amount of resistance.
Maybe it just I had a bad experience, but i will say that overall the set is noticable smaller than a we tech stock body.
