I have personal experience with the sport. I loved it when I had it...a great value for money. It never jammed on me and it produced better groups with the 5R barrel than my colt does with the chrome lined one. It was super light-weight and felt quality. I never noticed the absense of the forward assist in practice.
As far as upgradabilty, it's milspec and has a milspec tube, so no issues with milspec stocks. It will accept a rail system and the flash hider isn't pinned and welded, so you can swap it out. It also has a top rail for an optic
I sold it to fund another project and because the girl I bought it for really turned out to kick me in the balls. Bad memories and all...but the gun itself was fantastic
