I've personally shot 3 different tf11's, the first one (in 2009) was great, had no issues and worked great.The second one(2015) I bought because it was on sale for $35, and it was terrible, after the first clip it just locked into full auto and wouldn't stop until you removed the clip. After trying to figure out why without any result I exchanged it for another one, this one is alright, when on semi it always shoots 2 rounds, but besides that it's alright.Now for how the guns actually preformed.Accuracy is terrible! BUT what do you expect from a m11 replica? It's practically as accurate as the RS, pretty realistic.The slide doesn't lock back when the mag is empty, which can suck with its very fast ROF. It is very hard to find the extendable stock for m11 airsoft guns, you either buy one that comes with it or deal with not having one. The silencer is also tough to find but they are out they're.All in all its fun to shoot but it's not really worth the money, just pay the extra bucks to get a more reliable GBB that also has replacement parts, the only thing you can buy for the tf is an extra mag. If you see one for under $50, definitely buy one, or two!
