i took it to the range and fired 100 rounds , all rounds went off without any issue.
i only shot at 25m and i was shooting high and to the right. i shot with the notch sight first , followed by the aperture sight and then the bushnell trs-25. considering my eye sight isnt the best , i was pretty happy with the 3" grouping with the notch , 2" with the aperture and the same with the RD. im pretty sure i can improve with more practice and changing the RD to a aimpoint T1, and better ammo.
the smg is well balance . i didnt feel the weight shifting like i did with open bolts smg prior to the round going off and that was due to the closed bolt/hammer system . the trigger was noticeably stiff for my liking. the stock was angled that puts my eye level to the iron sight, it did not lock solidly in place and judging from the set up i dont think i can do anything about it, the wire against my cheek was ok , not as sharp as the factory VZ folder.
i checked the casing after fire , it had scratches all around the casing with a slight indent at the top, ofcos it was blacken bcos of the blowback. a good cleaning will be needed.
it was surprising easy to dismantle and ofcos doesnt require alot of counter top space.
1. grab the top cover catch that is attached to the main springs on both sides and move it forward , and then with the other hand remove the top cover , then remove the main springs , move the bolt rearward and up, it comes out. please note when replacing the main springs, make sure the buffer end where the pen is pointing is pointing down .
2. press barrel nut lock and unscrew the nut, the barrel will slide out . when replacing you need to push down on the lock again when tightening the nut.
3. to separate the tigger housing to the receiver , punch out first the axis pin and then the sleeve.
4. pivot the trigger housing down.
5. to remove the hammer spring , using a flat head screw driver and place it under the axis pin and lift up.
6. when replacing , put the axis pin in first and then assemble the rest and hook it to the hammer and squeeze the spring assemble till its in the axis pin.
7. to remove the stock, unscrew the tiny screw in front of the stock , unscrew both sides while the stock in the closed position, then pull back (open) the stock till the tiny stopping pins appear , gently punch them out .
8. the grip is held in with one screw and the HG with two .
that is as far as im going to go for cleaning , if anyone knows how to remove the trigger/hammer and the extractor and firing from the bolt (my screws wont budge) , please post .
btw, the cleaning tool is also a front and rear sight tool .
i also did a test of the bore with cold blue and im happy to report to those lazy buggers like myself , its chrome .
all in all , im very happy with my first SMG , its a fun gun to shot .
