That is a Smith & Wesson .22 LR AR-15 knock-off. It is a plastic gun which weighs about 4 pounds. The optic is an Eotech with 65/1 reticle. I think it is the one that takes N batteries. And if I recall correctly the vfg is a cheapo from GG&G. That is my kid's high volume shooting practice rig.

My kid's AR15 in 5.56 has a Daniel Defense upper with Daniel Defense 16 inch CHF CL 1-7 bbl and A-frame front sight. It has a BCM mod 3 charging handle, a Larue LT110 mount, and an Eotech with the 65 moa ring and 1 MOA red dot. It also has a quick release mount behind the Eotech for the Eotech 4x magnifier, which is usually in a pouch. The forearm is a magpul MOE with Magpul MOE vgf. The lower is a CE billet (there are a million lowers out there...) put together with a Daniel Defense LPK, milspec buffer tube, H1 buffer, MOE grip and MOE butt.

My kid's mid range gun is very similar, but has the Trijicon 4x acog RCO with red chevron and windage hash marks on larue mount, and a DD free float forearm.

THe pic below shows his close range AR15 described above, but I took that compensator off and put a Vortex FH on it.
