Convert to M4

[ccrn]

I have a newer Colt HBar with 20" barrel and flat top reciever. Its an excellent rifle and served me well before deployment. Now that I have returned I'd like to have an M4 like I had while deployed to attend some training courses.

It occured to me the other day that I could convert this rifle into an M4 type platform by having a local gunsmith install a Wilson 16" barrel, and an adjustable buttstock onto the lower reciever all at an affordable price compared to buying a new (or used) carbine.

Does this idea have merit or would you guys recommend otherwise?

Thanks in advance-
