Personally I wouldn’t pin a UBR. It’s not an easy stock to pin. The ACS or SOPMOD is a much easier stock to have pinned. For that matter why not get a Sully Stock so you don’t have to worry about pinning it? Last time I visited my friends behind enemy lines in CT they were running Sully Stocks on 16" middys and it was an awesome set-up. The length of pull is just about perfect for me.
As far as length of pull with the UBR goes, a fully collapsed UBR is a good length if you shoot squared up with the stock tucked in a little further into your chest like so:
I am 6’ 220lbs and this is how I run my stocks. I prefer a SOPMOD one click out from fully collapsed.
If you shoot bladed, then this stock position will not work well for you.
I 3rd this option. I can’t really understand paying $250 + the cost of pinning it, simply to have it do something that the Sully stock does very, very well at half the cost.
I have a rifle that was originally called a “commander” from Sully, 16" barrel with a full length handguard. Now the term recce is more fitting. It has a sully stock and it is a solid stock, a little heavy, but solid and is tough as hell. Sometimes I thing about changing it out for a ACS etc but it is very comfortable, dependable (no parts to break), and always ready to go, no need to adjust etc.
Really work taking a closer look at, play with one of you can.
I don’t get paying that much money for a collapsible stock with the strength of a fixed stock if it isn’t collapsible anymore. Just buy a fixed A2 stock or a fixed stubby stock if you prefer that length. Buy ammo with the change.
I only shoot bladed if the situation dictates I have to. I prefer being squared up when shooting if possible. It’s just more comfortable and it’s how I shoot at work.
I personally feel that bladed has it’s place but not in modern gunfighting.
It’s OT but I don’t think Paul would mind me using this as an example. Read the following story and you’ll understand why bladed is not a good habit to have.
