Justin Edinburgh is running the rule over a number of trialists.
The Gills boss still has room in his squad for new additions and a handful of players are hoping to make the grade.
Four trialists featured for the Gills at Concord.
Boss Justin Edinburgh said: “We need to get some bodies in and we have some that were recommended in certain areas.
“One or two did okay and we will have another look at them against Billericay (on Wednesday night).”
Former Scunthorpe United defender Marcus Williams started Tuesday night’s game at Concord playing left-back.
The 30-year-old has spent his career playing in the north of England but was most played for Indian side Kerala Blasters.
He was replaced at the break by East Thurrock’s highly rated winger Tom Wraight.
Wraight was in familiar surroundings, having played all his career in Essex, starting out at Tuilbury, moving to Witham Town and then East Thurrock.
The youngster has yet to make a break from non-league despite interest from a number of league clubs. Last year he had a trial at Ipswich Town.
Josh Lelan played right-back for the Gills in the second half at Concord.
He was with League 2 champions Northampton Town last season, where he played 11 league games. He is a former Derby County junior and has had loan spells at Gateshead and Swindon.
Dulwich winger Rhys Murrell-Williamson was also in action. The 22-year-old dropped into non-league after beginning his career with Celtic and having a spell at Crystal Palace.
