Is there a way to attach more rails , put a grip on the pump , or put a suppressor on it?

How long would it take to arrive?

The blaster replicates the Benelli M4 in a full size scale. As most of you should know, no. It's not semi auto! This Replica is pump action only. It's a darn-pretty thing to look at and the entire body feels lightweight yet sturdy enough that it won't break on you after a few pumps. I wouldn't recommend to continually dry fire as the wear and tear of your blaster will depend on how rough you treat it. While these blaster's perform decently well, it's not the best. However, I don't think this is why we would purchase these types of realistic looking blasters. These blaster's should remain as strictly wall hangers or at home plinkers, because at first glance, they look super realistic.

As I stated before, the body does feel sturdy enough in your hands but I can't say the same for the charging handle!!! It completes the look for the Benelli M4. Sadly, mine had snapped off within the first hour after chambering a plastic shell. Somehow, I already predicted this as its made from a super flimsy and weak plastic material. It's probably best to fabricate your own charging handle which is exactly what I am currently doing while typing this review.

The plastic shells are a long type and I'd suggest for buyer's to purchase extra! With the variety of shell ejecting blasters out on the market, not all are compatible with the same shells which make them hard to find at times. I am glad ZhenduoBlaster provides buyers with the option to purchase mores shells on the same page. Thank you ZhenduoBlaster!

Also NOTE from my posted photos: This model does not come with a full size stock! I had used a stock from an old CYMA tri shot airsoft shotgun which miraculously, worked and fit like a glove. I was stoked to see that it used the same type of screw and mount, and allowed me to complete the look featured in popular movie franchise which I'm sure this particular UDL model took inspiration from. :D

Overall, I have been having a lot of fun plinking bottles and cans around my home. Boys will be boys, and our attention is easily captivated by super cool toys! I am happy with my purchase, and would highly recommend this blaster for any fans of the Benelli M4. Thank you ZhenduoBlaster!!! I definitely will be buying more! :)

Great toy to mess around with as the handling is nice. Just wish they had a full stock version, but it's fine as is too.
