New Frontier Armory recently announced their latest offering in the AR-15 pattern of lower receivers with the C-4 bollet lower featuring side folder.

In some cases to convert your standard AR-15 to a side folder could cost a few hundred dollars.

However if you know that is the set up you plan on running why not just go ahead and buy a dedicated lower that has the side folder integrated in.

Not only is this option cost effective but in some cases it might also prove to be the far more reliable option.

New Frontier Armory’s side folding lowers are also available in few other models including the popular C-5 pcc lower that accepts MP5 style magazines.
