"Cool kit for those with a gbbr. Used this for my WA gbbr m4 franken gun. You can use the complete kit, even the spring. Good recoil, heavier buffer, higher fps, but the spring slaps around in the tube and it's loud. I would recommend it for your gbbr not sure about real steel. I bought two and would buy again if I get another gbbr.

"Got this for my Ra-tech custom WE-m4. Sadly it doesn't work with the Ra-tech 2015 steel bolt or the older Ra-tech steel bolt. The BCG binds about 20% of the time and it requires you to either smash the forward assist or bang the stock on the ground to send the bolt forward. However it works wonders with the WE stock bolt.

Pros: Great build quality.
nice and hefty buffer.
great buffer spring.

Cons: The inner diameter is slightly smaller then an actual milspec buffer tube.
the inside of the buffer tube has small ribs along the inside which can cause
binding with some bolts.
