New over at X-Fire have added two new inner barrels to their lineup on their English site, one for the Desert Eagle and one for the Marui NBB Mk23 Socom. The inner barrel for the DE increases accuracy reducing grouping from 84mm(w)×77mm(h) at 8 meters to a grouping of 57mm(w)×54mm(h).
The Mk23 Socom barrel also increases accuracy reducing grouping at 8m from an already quite impressive 57mm(w)44mm(h) to 30mm(w)44mm(h).
