Reduce stress on polymer lower receiver-ar15?

[Gilcontr]

Hi, I'm new to guns and decided to build an ar15 to start off. I went ahead and bought a polymer lower and have a JD lower on order. I plan on building both lowers. I was gonna start with the polymer one and was planning to go featureless (using a hammerhead and attaching the stock to it) because I figured that taking the stock off of the buffer tube would relieve some of the stress on of the rear of the lower receiver. Am I right in assuming this or do I have it backwards?

Thanks in advance!

You still have a buffer extension to worry about unless you are going blowback 22lr or the like.

Yea but I meant by the added stress of shouldering the stock and the shock while firing. I Dunno, maybe I'm just over thinking it.

Probably.

Is it a NFA LW-15? IIRC haven't read or seen anyone with any probs in normal use re shouldering and firing...

Maybe after they get run over?

The stress comes from the bolt cycling and the carrier slamming into the back of the buffer tube. If anything you are adding to the stress because with a stock at least the force is transferred from the buffer tube through the stock into your shoulder.

So you're concerned about the impact on your shoulder? Unless you've got severe problems with your shoulder I have to say the shock is negligible, IMO; I could shoot an 'AR all day. Shotguns with 3" shells on the other hand...

This is what I was trying to get at. That's what I figured. So maybe doing what I planned is not the way to go. I'll go ahead and put the stock on the buffer tube. Thanks for the input!

The lower is an FMK patriot. I'm sure they wouldn't sell it if it were to shatter into bits. I figured I would just do my part to ensure that.

Lol even then it'll work. Insane

Um, unless I'm missing something, the lower better be able to handle the normal stress of having a stock attached to it. If not, get a different lower....
