Would this provide an h2 feeling for 5.56? I am currently having light primer strikes with the original one that came with the stock

This will most likely not function in a rifle chambered in 5.56 due to the 9mm bolt face being flush with the carrier and the 5.56 bolt protruding.

Can this Strike Industries AR PDW 9mm Buffer be used to a 45acp direct blowback too? Expert Answer

You can use the Strike Industries AR PDW 9mm Buffer but it may not be the most efficient, reliable buffer for 45 ACP. I would recommend a buffer that is about 8 oz. to ensure proper feeding, ejection, and reliability. You can find the Angstadt Arms Buffer Kit for 45 ACP using the following link:

Good...but by STRIKEn, May 14, 2023
First, works great with 9mm and the shorter pistol buffer tube that's just over 5". It takes some effort to get it i n the 5" tube however, it's worth it. NOW THE BUT.....YOU CAN'T BUY IT WITH THE 5" BUFFER TUBE. So if you want this, you MUST buy ...

Great product by Dan Roselip, April 16, 2023
Perfect for the 9mm pdw. Bought it install and has ran flawlessly. Would definitely recommend this to any who need a smaller length buffer. If you don’t have a shorter buffer it’s not necessary. Definitely would buy again

Doesn't go back enough for the LRBHO by Johnjohnlepocon, Verified Owner, February 8, 2025
The 5" SI AR PDW tube isn't long enough for it to lock the bolt back. It can only allows it to lock on the carrier and not the bolt. This spring and buffer also to ridiculous of an effort to get the spring inside the buffer tube. I see it wanting to ...

Perfect solution by Justin Ritter, Verified Owner, March 17, 2024
I have a psa 9 mm which shouldn’t need this product but unfortunately I had some excessive reverb and trigger slap. It has solved the problem 100%. Kind of wish they would just sell the stock and the heavier set up as an option so you don’t have to u...

Product Info for Strike Industries AR PDW 9mm Buffer

The Strike Industries AR PDW 9mm Buffer enables proper configuration of the SI PDW Stock, SI PDW Stabilizer or pistol length receiver extension to work on most AR-15 9mm direct blowback systems on the market. Made from steel, the buffer housing holds two (x2) tungsten weights and gives you a total of 4.6 ounces. The buffer pad on the buffer housing is made out of a resilient NBR rubber material to absorb the 9mm direct blowback impact. This 9mm buffer includes a flat wire buffer spring that is fine-tuned specifically for the buffer in SI PDW systems and most pistol length buffer tubes, making it simple and complete. Flat wire spring design packs more energy than traditional round wire springs, giving it increased bolt power. Known for efficiency since the flat wire spring is able to store a larger amount of energy in a smaller space. The Strike Industries AR PDW 9mm Buffer gives you the option to use the SI PDW Stock/Stabilizer or a pistol length receiver extension reliably and accurately on an AR 9mm build.image
