I bought this m203 about 2 months ago ,trigger does not function and didn’t get the barrel mounts. And I paid more money.
Great store I recommend ordered goods great quality. The goods arrived in order. Satisfaction guarantee
This replica is awesome, im a big fan of it. If you want a great platform to be spécial this one is for you, vmag fit well and the marking wow
Works fine on co2
Supposed to be VFC compatible. Requires modification and removal of steel from the base collar first. Unfamiliar threaded insert to forward end of barrel. Not an airsoft barrel feature. Very heavy. I do not recommend this product.
