Sweet pistol brace but comes with downsides... - Strike Industries PDW 2-Position Stabilizer Brace

Really awesome "brace" here. Installs fairly easily. The spring mechanism performs flawlessly and pushing that button and having the OTF like deployment will make you the envy of all those guys at the range rocking those SBA3s, KAK braces. This is really the only true PDW brace on the market as the SB and Maxim braces are not spring loaded. Not the most comfortable brace when it "occasionally and sporadically" makes contact with your shoulder tho, but it is not uncomfortable either. The cheek weld is actually pretty good considering the design. It has performed flawlessly thus far on my 10.5 inch 300 BO pistol with no cycling issues whatsoever. The downside is mainly the castle nut will come loose after 40 to 50 rounds. Since there is no end plate to stake the nut to the 2 inch long castle nut is free to back out and loves to do so. The only thing I can think you can do about it is to add some sort of non permanent lock tight. Also the plastic cheek weld piece just slides over the tube so it can also come loose and fall off. I know sacrifices had to be made due to the design but these issues mean this is mainly just a range toy for me and not something I would use for self defense purposes. All things considered tho the Viper brace is another big win for Strike Ind.
