airsoft gun

Really know nothing about this gun, selling it as it’s too heavy for my son. He’s only 8 and this was gave to him as a present. Comes with everything. Iv included a link to the shop he got it from to help with any info. Thanks https://www.tsairsoft.com/lancer-tactical-lt-02-g2-m4-cqbr—combo-pack. Will accept any offer on this as he is just looking to get a smaller , lighter one. Please ignore the fps section as not a clue what this is.
