Frequently Asked Questions

What are common problems when installing an aftermarket folding stock on a Remington 870 Police Magnum?

A frequent issue is the bolt thread pitch mismatch; the original stock bolt might be 1/4-28, while aftermarket kits may include a 1/4-20 bolt. Additionally, the bolt length can be incorrect, requiring sourcing a specific size or using washers for a secure fit. The sling swivel may also obstruct installation.

How do you identify the correct bolt for a Remington 870 folding stock installation?

You must determine the correct thread pitch and length. The original stock bolt often has a 1/4-28 thread pitch. Measure the receiver's threaded hole and compare it to the bolt provided with the new stock. If the bolt is too long, a shorter one or washers may be needed.

What tools are needed to install a folding stock on a Remington 870?

Essential tools include a screwdriver, an Allen wrench set, a socket set, and potentially a hammer for persuasion. You might also need pliers and access to a hardware store for sourcing correct bolts and washers if the provided ones are unsuitable.

Are original Remington 870 Police Magnum folding stocks durable?

Original Remington 870 Police Magnum folding stocks are generally considered flimsy. They are typically made from folded sheet metal with a hard plastic pistol grip, which can be uncomfortable and prone to wear over time compared to more modern aftermarket designs.
