Awesome addition to any build

Written on Jul 29, 2026

These are well made and lighter than mil-spec steel ones. They will not rust or corrode like mil-spec, either.

Excellent product and all I use in my builds.

This is an excellent product. It is well made and finished, and reduces noise inside the buffer tube. I use these springs in all of my builds.

Will not work in certain applications

Written on Jul 29, 2026

Although the product is well made and seems comfortable to hold, it will not work on an AK with a standard length rail system. It blocks magazine insertion. I had to return the item, and OP return policy is excellent.

Great Grip

Written on Oct 15, 2024

This grip is very comfortable. It has a palm swell exactly where it needs one and sits at the perfect angle. (Slightly less of an angle than a Magpul K2) The rubber coating is comfortable and tacky. I have several K2s, but this grip is a huge improvement over that design. There are two cons, however: it does not include a grip screw or a plug for the bottom for storage.

Don't waste your money

Written on Oct 12, 2024

Although the proprietary parts made by Geissele were well made, this kit came with the worst roll pins of any lower kit I have ever encountered. The bolt catch pin broke in half during the installation, about 3/4 of the way in. The trigger guard pin was doubled up. There was a smaller pin stuck inside of a larger one. Luckily, I had a spare one laying around. For the price, I expected better. If you get this kit, buy seperate pins.

Best trigger pins

Written on Oct 12, 2024

I use these in all of my builds. They are precision machined and polished stainless, so they improve the feel of all non-cassette style trigger systems by lessoning the friction of the pivot point for both the trigger and hammer. They are even better than the pins some "high end" triggers come with. The best, and worth every penny.

Best Buffer Tube

Written on Oct 10, 2024

I use these for all of my builds. They are expertly machined to completely cover the threads on the inside of the receiver, and fully support the carrier assembly in travel, while still allowing the separation of the upper and lower. It has drain holes in the end and in the stock adjustment pockets. It is beautifully finished with a subdued, black logo underneath,not an ugly white or other color logo like some manufacturers. If you are looking for the absolute best M4 style receiver extension/buffer tube, this is it.

Great product

A great looking castle nut that threads on easy. Machining is perfect and so is the Nitride finish that matches other Nitrided parts. This is the best looking steel castle nut for the money.

Great stock option

Written on Sep 08, 2024

I love this folder. It looks great on the Vector, it's lighter than the original mil-spec buffer tube/stock, it's length is adjustable, it can fold to either side, it bolts right on with no adapter needed, it's US made, and it has a couple of spots to hang a sling. It's all metal so it's incredibly durable. What else do you need?

Great mags

Written on Sep 08, 2024

This is the best way to feed your Vector. Increases the capacity of Glock 17 mags to 40 rounds and matches the asthetics of your Vector. Just as reliable as a standard Glock magazine.
