Thanks to AT3 great processing and delivery this is my first build I love the feel and look of these greatly satisfied with them install was super easy and function for griping and maneuvering the mag with this add-on is completely easy and my experience is definitely bringing me back for more parts and accessories
Fast, free shipping (over $50), hand guard is awesome, easy to install, fits and looks great! AT3 tactical will, from now on, be the 1st website I check for gun items!
Great upgrade over the standard one that came on my 5yo Daniels Defense rifle. I like the asymmetric design to give more reach over the forward assist. It has enough stickout to be an easy pull even around the backup Magpull flip ups.
Needed a extended charging handle to clear my 1-6x and offset Rmr and this fit the bill, feels solid and works great, can't see spending $40-80+ for Gucci handles when mil specs been working for the life of most guns

Build an exceptional AR-15 with high-quality lower parts kit from AT3 Tactical
Among the different AR-15 parts, the lower parts kit is the most important.
In AR-15, the lower receiver is considered the legal receiver or the legally controlled part. Hence, it’s the part that is serialized.
