Question: Does the bolt slide back when fired?
Document: The rifle looks and feels great, I don't recommend it but when you take the orange tip off it looks mean, nice to just hang on the wall I've shot it a few times and it works great  I put the tip back on when I take it outside, overall it's a great rifle, son hates it when I use it for our battles, so for the most part it's a wall hanger. Probably order another one for actual battle use with my son.
this airsoft rifle is nice to be a "beginner" kit on which comes with a basic 8.4 voltz battery and a charger wich if you forget your battery is charging it will overcharge it but if you take care of that point everything else is going to be fine.
exactly what I wanted.good range, good power.great accuracyits an awesome platform for a field rifle, easily upgradable for a DMR
comes with a nice medium green or dark green coloured sling, I haven't used it that much to tell if its strong or weak. the rifle has a cool rate of fire and nice muzzle velocity. comes with a 400 high cap quick wind metal magazine and fits perfectly and tight in the rifle.
The body is constructed out of an ABS Polymer (that's a fancy way of saying really strong plastic) and has a steel buttpad and sling mounts. The imitation heatshield is also plastic. The CYMA M14 shoots 390 to 410 fps and has a rate of fire of about 15 BB's per second, that's about on par with most M4/M16/AK rifles.
I will definitely recommend this rifle
I purchased this Airsoft gun from Airsplat for 139.99 USD. Included was the gun itself, 1x 350 round high capacity box magazine (meant to resemble an M14 20 round magazine), a cheap sling (I generally do not recommend using this due to its poor design of the clasps), an 8.4v 1600mah battery that will last all day, a "trickle" charger that will charge your battery in 4-6 hours, an unjamming/cleaning rod, and an instruction manual.
I had only two problems with it. 1) The charging hangle guide rod snapped off, making the charging handle unable to be cocked (though there is no real use for it anyways) and 2) The imitation gas tube lost it's set screw the first night I used this, it turns out that this was easily fixable and probably not a problem with the gun. After being fixed, it has presented no problem for me.
