Great handguard and barrel retention - Midwest Industries DPMS 308 Low Combat Rail M-LOK Handguard

Midwest Industries doesn't disappoint here on the overall quality/fit/finish - however I will say that I had to carefully trim down the top blue insert (the little feet on it) so that it would seat properly between the barrel nut and the upper receiver - I think this can sometimes happen when the barrel extension outer rib is a little thinner, like on the Proof barrel I bought. Once this was completed though, the barrel nut is completely firm and stays put.
