Getting a Grizzly 12.5 will Magpul MOE forestock fit and other questions

[Don'tkillbill]

If I can locate a tactical choke I will see how long it adds to barrel. Would the magpul rear stock be lighter than the grizzly's stock?

I have a Norinco 14" which I believe is the same and I installed a MOE forend - if the magazine cap has a ring with a sling loop, this ring gets in the way of the longer Magpul forend. I replaced the magazine cap with a Remington Universal Magazine Cap w/ Swivel Stud and the MOE is able to clear it.
Also, on my gun, the MOE was a very tight fit that I had to install using a mallet, it did not slide on easily like what I had seen in a video, and as such I'm not sure I can even remove it.

I don't know about the SGA rear stock but I think it should be both lighter and a bit shorter. I hope to do this upgrade as well soon.

Thanks for the note. The rear stock is a big chunk of plastic
