SLR15 LOWER RECEIVERS
Our lower receivers were featured in the December 2008 issue of SWAT Magazine.
We are running a special price until 09/01/2009 on our SLR15 Lower Receivers, $118 (plus shipping and handling).
Order HERE. We are approved to ship to California, and comply with all California and Federal Laws. These may be shipped directly to the FFL of your choice.
We have a batch in the works which should be ready to ship in about 6 weeks.
SLR15 Lower Receiver Specs for this CALGUNS Special Priced Offer:
* T6 7075 Forging
* Enhanced Magazine Well
* Trigger Creep/Uptake Adjustment with Set Screw
* Broach Cut Magazine Well
* Front of Magazine Well Checkered
* Fire Control Markings (Safe/Fire)
* Caliber Marked: MULTI
* CY6 Triangle on right side of magazine well
These are machined from T6 7075 Aluminum Forgings. These have a deep bevel to the magazine well for feeding and feature checkering on the front of the magazine well for grip. The magazine well is broached so the walls are thicker and stronger. The buffer tube threading is reamed and bored which keeps alignment at less than one ten thousandths of an inch variance for proper alignment.
Receivers are marked:

Magazine well comparison from top view. The receiver on the top is made by a large manufacturer, and the one on the bottom is ours. On the top receiver you will notice the side of the interior of the magazine well, you will see square cuts that are located about 1/2" from each corner and at the magazine catch area. These square cuts on the sides of the magazine well can indicate that this is milled out, as the square cuts (stress relief cuts) are done to reduce the stress while milling out the magazine well. These square cuts also thin the walls, plus square cuts can be a weakness as heavy stress can cause square corners to crack. Our receiver doesn't have these stress relief cuts (corners) as we broach cut them. The broach method that we use allows us to make the walls thicker and stronger, and yes they will accept Magpul PMags!!!

Magazine Well comparison from the bottom. The receiver on top is made by a large manufacturer, and the one on the bottom is ours. You will again notice the square stress cuts on the top picture. You will notice the broach cut on the lower picture, our receiver. You will also notice the area on the underside of the trigger and in front of the trigger on the top receiver that it has excess metal, where ours (bottom receiver) has been machined cleaner, plus compare the machining where the front of the trigger guard locks into and compare the two.
View from top of trigger group area. Receiver on the left is made by a large manufacturer, and the one on the right is ours. Notice the thickness of the walls on ours as compared to the thinner walls on the receiver on the left.

View from the top comparison of the buffer tube threads. The receiver on the right is made by a large manufacturer, notice that the buffer tube threads go all the way through past the buffer retaining detent. When the threads go past the buffer retaining detent, this indicates that this was most likely threaded using a tap. When a tap is used for this machining step, it could possibly be off in any one direction which could cause the buffer tube to be off in any one direction. If the buffer tube is off in any one direction it could cause the bolt carrier assembly to rub against the inside of the buffer tube. The receiver on the left is ours, you will notice that the threads stop about half way through the buffer detent area. When we machine the top of the receiver we establish this as our water table and all other machining steps are based on this. When we machine the top of the receiver and establish this water table, the buffer tube threads are then reamed and bored, which gives us a tolerance of less than one ten thousands of an inch that the buffer tube is kept in line with.
Underside back grip area comparison. The receiver on the left is made by a large manufacturer, notice the excess metal in the middle. The receiver on the right is ours, notice the cleanliness.
