Receiver extension

[No.6]

While cruising SAW's parts catalog, I came across three different RE's. One is extruded and two are forged (one has a NSN number).

SA61574E BUTTSTOCK, RECEIVER EXTENSION - RIFLE (BUFFER TUBE), EXTRUDED $35.00

8448581 BUTTSTOCK, RECEIVER EXTENSION - RIFLE (BUFFER TUBE), FORGED 7075-T6, (U.S. NSN 5340-00-992-7297) $54.00

SP61574 BUTTSTOCK, RECEIVER EXTENSION - RIFLE (BUFFER TUBE), FORGED 7075-T6, COLT GREY $75.00

My question is: Besides the obvious (extruded v. forged), what's the difference? I know the forged, in theory, would be stronger, but would it be worth the extra money? Is there any difference between the "Colt Grey" and the NSN one, besides price?

I would go with the 7075 forged no questions asked. I woyuld go with the 54.00 one or get a LMT or Vltor.

Hello,

Keep in mind that the RE's you listed are for fixed stocks, so if it's a sliding stock rear extension your needing, then you'll need to order Part No. SP64702

That being said, I'd spend the extra dollars for The Genuine Colt part.
