Description
This receiver is machined from a solid block of 7075 billet aluminum and is much more rigid than a standard mil-spec receiver.
Ejection port opening is .665″ wide for use with 458 SOCOM, 375 SOCOM, 450 Bushmaster, 12.7×42 etc, but can also be used for smaller calibers such as 5.56.
The bolt carrier thru-hole is machined in one pass from one end, unlike cheaper receivers that have been bored from each end, resulting in a seam/step in the middle.
This is a very nice upgrade for your heavy hitting, heavy recoiling big bore upper.
Shipped complete with standard mil-spec ejection port cover and forward assist assembly installed.
Optional caliber specific ejection port covers are also available for this receiver.
Right hand ejection only.
Weight: .74 pounds
