MAS Defense had it
June 22, 2022
: William Phillips from Leander, TX United States
Several other sources were out of these, but MAS Defense had them. These are great for those AR pistol builds, and you have a hard time beating MAS Defense for fast shipping and customer service.

Lousy packaging
April 3, 2022
: ROBERT PENDRICK from Prescott Valley, AZ United States
Seller shipped a buttstock/pistol brace with buffer tube in a USPS Priority BAG. Not a box! Product box was smashed luckily just a couple scratches on buffer tube you really cannot see! I bought 2 items minutes apart seller shipped items separately one arrived 4 days later! I sent an email asking questions why NO RESPONSE and now they want a survey last time I buy from these people!
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
MAS Defense Reply: Bob, the SB Tactical brace comes in a box. We put the buffer tube in the box then put the box in a Priority Mail Tyvek envelope to ship. We have shipped thousands of braces and stocks this way without issue because they are not fragile items. I apologize for USPS crushing the box and the scratches on the buffer tube that you "really cannot see" but am glad everything made it to you safely.
As far as the 2nd shipment being delivered 4 days later, we have no idea why USPS took longer to deliver that package to you than the first package. Both packages shipped on the same day at the same time. Unfortunately, we do not own USPS and can not control how they operate.
Thank you for your business and your feedback!

The products are all made to the upmost quality and precision. Very professional. Fast recival and shipment. We build alot of custom firearms and MAS is the ONLY company we trust with aftermarket springs and upgrades for our SIG builds. From one service member to another thank you for your service.
