UTG Pro 15" M-LOK by raptor, Verified Owner, September 25, 2023

good quality by dan, Verified Owner, September 11, 2023
Bought this to spiff up my Mother’s rifle a bit with a red theme . This is the 3rd utg pro handguard I’ve bought and I believe it to be the best value in a handguard. The attachment system is easy and is very durable
