Yep, pretty much. Though CA has a lot of proprietary parts, you don't really need to replace most of them anyways. And the good news is that CA is finally releasing locaps for the gun soon.

I currently own a TM M14 and it was shooting farther than my upgraded TM M4 S system with a Guarder 100 spring in it, as well as going farther more accuratly!
I personally want from a gun the availability of replacement parts if shit breaks i mean come on its airsoft not real steel. Or you can pull a dumbass move and try to fix Shit yourself like i did, long story short made a dumbass move and i can sleep tonight because the parts are available to fix it and in a matter of days working againe due to getting it fixed by a gun tech lol

your call but if it were me spend the extra $ at first and you wont regret it! its a TM The Quality speaks for itself

..What?

listen Neil. I was in your boat not too long ago. i couldn't decide between the two. go for TM. i did my research and i concluded that the TM was the better choice bar none. go for the TM and i promise you, that you will never look back except maybe at the stock color that you chose.
