How can I adjust the brace? Seems hard to adjust. Do I need to loosen the lever?
Joseph on Aug 19, 2019
BEST ANSWER: I had to put a light coat of oil on the tube and lever. Then I worked it several times and it worked better. You can also use graphite on the tube instead of oil.
Is this lower excellent for building a 556?

BEST ANSWER: I have the same LPK on a PSA 10.5 pistol. Only difference is mine has the SBA3 brace. Feels
like any other mil-spec LPK I have owned

Not impressed with Brace
Overall the PSA SBA4 is pretty decent. All parts came oiled, organized, and ready to install. The one thing I have to say is the brace does not fit to the buffer tube. Extremely hard to adjust. I would suggest ordering a diff brace then the one in this kit. Might be just mine will be testing others with this buffer tube.

Pretty good kit
Its overall a very solid group of parts, only issue I ran into was the pistol grip wouldnt fit right on the lower I had so I resorted to using an extra A2 grip I had lying around

Very surprised.
I ordered the kit on 07/06/2019 and it finally made it to me on 07/23/2019. It only took 13 days to ship, which I've never had that problem before. The kit arrives and everything looks good as normal from PSA minus the buffer tube. The tube had some pretty bad gouge marks on the inside upper area of the tube that could be visibly seen and felt. I began assembly and everything goes great without a hitch. I get it all put together and go to slide the brace onto the provided tube. Disclaimer: I know how to install a SBA4 brace or any other stock for that matter. When I first attempt to slide the brace on I noticed that the fitment was very tight. Based on the other reviews I've read I figured this was normal. I then attempted to move the brace into the fully collapsed position at which time it became stuck. I was eventually able to pull the brace back off. I looked inside of the brace and could not see any obvious defects so I attempted again. The brace fitment was so tight that by the time I was able to make an adjustment I would either pull it all the way out or push it all the way in, due to how hard I was having to push or pull on it. I trouble shot it based off a SB's website but nothing worked. I contacted PSA and was advised that I needed to watch a video and would need tools to "adjust the brace". I advised the customer service rep that I would just like to send the brace back for a replacement which she advised was possible. I then asked how long the process would take to get the replacement part, and I was told approximately 3 weeks. She advised that once my part was received and reviewed, it would either be fixed or a replacement would be sent. So now i"ll have possibly over 5 weeks of wait time for a product that is defective, and will not know what type of replacement I will receive. Will they replace the buffer tube? Will they test fit a new brace prior to shipping it? I shall see in the up coming weeks.

I will add that other than the SBA4 brace and the gouged up buffer tube, all of the other parts I received in the kit were awesome and installed without a problem.
