Hello all, I bought the RF224 from Tenda and it is what I expected it to be, a fun, easy to shoot .22LR rifle. It’s accurate enough to 50m if I do my job. Like many semis, it needs hotter loads. CCI Mini Mag at 1235fps work fine, but do a full cleaning before you shoot as it arrives a bit gummy with grease. I would say at least 100 rounds to break in. The shipped magazines, look like Rugers but are not Ruger mags. Reliable enough but nowhere near Ruger quality or reliability. The 597 magazine converter is well known to be not reliable. ProMag banana mags for the 10/22 are not dependable, they do not lift the round high enough for proper chambering if loaded to 10. Less than 10 in the mag functioned fine. I have switched to using real Ruger magazines and that so far has resolved the issue. I put a cheap ass dot on it and for fun mini gun stuff it’s good. I overspent and put a Spearhead Machine brake on it and at this point the muzzle doesn’t move on firing offhand, so pull fast and have fun. The factory trigger is meh, but it does improve as it gets broken in. Replacement triggers for 10/22s are not usable in this rifle, so you get what you’ve got. Be aware that as others have noted, there is no way to lock the bolt open, so a chamber flag is a must. I find that annoying personally but how much it bugs you is up to you. I compared it to the Derya in the same price point, and chose the Adler because of the metal not plastic construction. I preferred the Adler, your mileage may vary.
In fairness it just looks cooler than a general 10/22. Not as reliable and not as accurate but at $429 it is what it is.
Cheers
