Top Quality, but read all instructions.
Quality is very high. As stated, you have to line things up. This was a little time-consuming for me as the receiving pin thread came to rest a little bit above the Magwell thread. I actually inserted an ice pick and with LITTLE pressure (taking care not to damage threads), lined the extended Magwell up with the new rod that replaces the original grip adapter pin, so the set screw would go in flush and be properly threaded. This worked for me (but, I am not a Gunsmith...and let me state.. if this had not gone well and I created damage...I would Cowboy Up...and blame myself, not Taran). It was well worth my time. If you are not good with tedious work, spend a few dollars and let someone install it. GREAT product. The efficiency of the extended Magwell on reloading using the 5+ basepads was not only impressive...it's fun. I wouldn't try to cut corners/save a few bucks with a product made by an unknown party. Go with Taran. I don't know them, I don't get a commission. I just know the quality is what they say it is and they were honest enough to state the caution/care it takes on the install.
