Solid brace - SB Tactical HKPDW HK Brace for HK MP5/HK53/MP5K

This is the way to go if you do not want to form 1 your MP5. Pros: The brace is solid and well built. By being collapsible it does not add any thickness to the gun that a side folder does. It has three positions settings and a QD mount for a sling. It did fit my Military Armament Mac-5 clone, which I was a little concerned about when first ordering. It looks good and it's as close to a stock as you can get if you do not want to form 1 the gun. Cons: It does add weight to the gun because it is sold metal not flimsy polymer. It's a bit pricey. It took a little effort to install because the fit was tight. Be sure and blackout the 3 set screws on the bottom of the brace before installing. The 3 set screws add support but they do have to be backed out in order to strip the gun for cleaning. Overall I am very pleased with it and would purchase it again. I am glad it fit my Mac-5 clone. I would rate it 4.5 stars if I could with 1/2 star deduction based on the price alone , not form or function. Also - Dirty J Designs makes a plug for the brace, which gives it more of a stock look for an additional $20.
