Nòng loe cho X-shot micro

I built one of these excellent X-shot Micro Re-shells 

(https://www.etsy.com/listing/1596006910/x-shot-micro-reshell-3-v11-sawn-off)

but I didn't want to remove the restrictors or fire half size darts. So I drew up a simple flared muzzle to make it look like the darts stuck out less.
