Already have a quad rail that you like?  Need a sling swivel?  No problem!
Many of you have quad rails that you are very happy with, but they may not have a sling swivel attached to them.  Rather than search the internet for a bulky aluminum picatinny sling mount, you have the option of sending it here for an upgrade.
We can easily attach a milspec front sling swivel to your existing picitinny rail with a hardened 1/8" steel roll pin.  This option offers a rock solid fail free mounting point with an 1800 lb breaking strength.

Swivel installation:  $25
Already have a complete upper that needs an A5 update?  No problem!
