Let customers speak for us
from 216 reviewsOne of the holster straps was in bad shape.
I contacted the seller and after a brief exchange of emails I was sent a complete holster to take care of it.
Its just as good as standard issue in the 90's.
perfect 👌 , lighting fast shipping and great service! Thanks again.
Exactly as described. Good condition overall.
Lost mine on the return trip from JRTC. This one was good enough to clear me with supply and saved me 150 dollars.
The bivvy bag had very minimal damage and was very easy to repair. I was expecting(and prepared for) worse. I also ordered a ruck sack that was just as described. I’m very happy with the order and I will give Forrest city my business any time.
Look great and in good condition for the great price. Thanks again been trying to find a good one to complete my old turtle that was on my cvc will i was a tanker.
