Absolute junk - Tdi Arms AKST-AK47 Buffer Tubes

Put this on my 556 AK. First problem was the sling loop interfered with my optic’s side rail mount. Since I wasn’t using the sling loop anyways I just went ahead and cut it off. I used a reasonable amount of blue loctite on the screws, let it cure overnight and hit the range the next day. Shot about 100 rounds and noticed how “rattley” my M4 stock was. On closer inspection I saw the TDI tube had shaken loose. No biggy I thought. This time I saturated the screw threads with loctite, screwed them in nice and tight, and let it cure for 48 hours. Went back to the range and put another 80 rounds through it. After getting home I looked at the TDI tube and noticed the roll pin that holds the receiver plate onto the tube had almost worked itself completely out. I checked the screws and they were loose again. Took the screws out and saw the threads in the tube were starting to strip. Bottom line this is made from 6061 aluminum and the threads can’t handle the repeated stress from recoil. TDI needs to either make this from 7075 aluminum or use steel inserts for the threads. Since I modified this it looks like I’m out 60 bucks. Do yourself a favor and look at something else.
