Quality product, but a couple things to know - B5 Systems Long Collapsible Precision Stock

This stock is very well made, but it gets a handful of poor reviews by people who donn't realize a couple things.
- The cheek pad is made in 3 sizes. A search for the stock will show you SHORT, MEDIUM and LONG in the descriptions which is referring to the length of the cheek pad. If you are going to put this stock on an AR carbine, keep in mind the rear pull of the charging handle and order the SHORT version, the MEDIUM may work if your LOP is at full length for your arms. If you are going to put this on a bolt gun chassis or a side charge carbine then you are free to pick whichever length you desire.
- B5 Systems sells an additional snap-on pad if you require more cheek height.

I was immediately impressed the moment I unboxed this stock. It's very solid and feels much like the quality of Magpul's UBR without as much of the weight and with the addition of adjustments.
- The polymer feels like top quality on level with Magpul.
- The fit to the buffer tube is snug. It slides reasonably well while having no play or rattle.
- The stock includes a nice little locking switch so that you cannot pull the stock off while adjusting with the pull down block.
- The adjustment wheels click nicely and holds position.
- The cheek pad is fully supported nice and solid on two columns and feels lacking in any unwanted movement.
- The buttpad is a hard base with a nice solid rubber pad with the right amount of softness and adjusts much like the cheek pad.
- The stock has two M-Lok slots on the bottom to put a rail for a monopod.
- The QD sling points are nice steel inserts and notched on the inside. This will not wear out like aluminum or plastic QD points.
- The weight is noticeable and good for balancing a front heavy gun, but in my opinion it's not too heavy.

I have this stock mounted on a Benelli 1301 semi-auto shotgun in which I intend to shoot plenty of 1600FPS buckshot and 1800FPS slugs. With this setup I will have the weight of the Briley M-Lok handguard as well as a SureFire Scout light and shell holders. This stock will help balance the additional front weight and all the weight will help manage the heavy recoil of the intended loads. This stock's cheek riser is perfect for the RMR sight height I'll be adding on top.
