FAQ

Simple look at Pros and Cons of 6061 vs 7075:

There has always been a debate about 6061 vs 7075. However, at LSD, we offer lowers, uppers, and matched sets in both 6061 and 7075 materials. 

In any case, here are our thoughts on the matter.

Pros for 6061 – Very strong. Reparable via aluminum welding in case of damage. Important when SBR’ing or if no further lowers are available in the future – It’s nice to be able to repair a receiver. Cons – Subjectively weaker than 7075 (see our Youtube Video of 6061 testing for a comparison and abuse testing).

Pros for 7075 – Stronger material (on paper) and more resistant to true “corrosion” than 6061 (this is virtually irrelevant with today’s Type 3 hard anodizing and other finishing options).  Cons – 7075 is not repairable via aluminum welding without access to very expensive equipment.

Many of you may not know, but the AR Stoner rifle was originally spec’d to be a steel receiver and to fire a 7.62 round. The military needed it lighter, and to have a higher capacity, so the 5.56 round was spec’d and they asked if it could be made from aluminum. The early 60s AR platforms were produced using 6061, but after the platform was deployed for use in Vietnam, it was quickly noticed that the 6061 was showing signs of early wear and corrosion from the constant humidity and SALT from handling by sweaty soldiers. 7075 was the quick answer, and hence became “mil-spec”.

Package Protection for Damaged/Missing Items:  Once the order has been picked up by your selected carrier, we can not control what happens to the package.

In the rare case of shipping errors on our end, email customersupport@lsdarms.com and we will correct the mistake as soon as we can.

Estimated lead time for variance orders:

Due to the increase in orders we’re receiving and the slow down in raw material deliveries, our variance order lead times are as follows (These are estimated lead times. Circumstances outside of our control may affect these times after your order is placed. We will not add to your existing order to “compensate” for increased lead times) :

  • Billet Lowers (most models)  16-18 weeks
  • Billet Uppers (all models)  18-20 weeks

***To be fair to all of our dealers, orders exceeding 100 parts of any SKU will be broken into smaller invoices/shipments based on available raw stock and other orders placed during the same time period.   

***Due to the rising costs of RAW materials, all orders are subject to price changes between the date of your order, and the time in which you are invoiced.
