Ok guys, I know several of you have been asking about these, so here we go... This will be a working review, I will add additional info, pictures, range reports, opinions, etc. as they come, this will also be a review of the PAP M92 AK-47 pistol in 7.62x39mm as well as covering the SB-15 and the upcoming version for HK style pistols. I really wanted to make this a full hearted, nutnfancy-esque review but I simply haven't had the time but this needs to get started. The brace comes in a cardboard box with a letter from the ATF, which I rolled up and put in the tube of the brace, and an extra strap in case you want to use both. First impressions aren't terribly exciting but it does inspire confidence, the mounting plate is sturdy and thick, the brace itself is made of a flexible yet firm rubber, not ideal but it works fine. The brace is tight on the tube but it can rotate, especially under recoil, however this works to your advantage as it will soon rotate to fit you perfectly. Cheek weld is decent and even for my fat face the 2 loops for the straps go unnoticed. Because this unit is attached only by the tension of your grip, make sure you get that grip screw torqued down or use some blue Loctite, I didn't use any and I'm approaching the 500rnd mark with no problems. This slightly lowers your grip and I've seen people also add the "sling mount plates" that fit under the grip of AK pistols to give them a sling point, I would not recommend this, it will bring your hand way down, making trigger control a bit funky. I would highly recommend the Hogue Overmold AK grip, it will give you better control of the pistol, which by the way is now quite heavy, this brace is no light weight, and the Hogue has a larger area to torque against the mounting plate. Using the arm brace as intended is completely ridiculous, good luck getting a sight picture, but we all know why we want these, the so-called "Paperless SBR". The brace is comfortable to shoulder and gives all the support you could ask for, and it makes a world of difference, if you've ever shot an AK pistol I'm willing to bet that you actually managed to miss the broad side of a barn, IMO unless you add a system like this, an AK pistol is simply a crowd pleasing toy, zero practicality, but now you have a fully capable AK that is incredibly portable and adds way better support than an underfolder can ever hope for. With the iron sights on the PAP, Krinkov style, and extremely crude, I was able to put entire mags onto 10" targets at 100yrds, I was shocked, we all know that's not impressive for a rifle, even an AK rifle should preform beyond that, but I am a crap shot and its an AK pistol! I'd call it combat effective to 200yrds, and I'm sure you could engage targets out to 300yrds with no problem if you practiced it a few times. This will be the extent of today's review, there will be more to come, be sure to ask questions if you have them but I am telling you right now that if you've even considered one of these arm braces BUY IT NOW!
