Perfect fit.

by -

Perfect fit for a Anderson lower. All needed parts included.

pretty short and makes my expensive non-wobble stock wobble

by -

I ordered this as a replacement and it A) only allows 3 positions, B) Seems shorter than the buffer tube it was replacing, and C) made my Hogue(non-slip/wobble) stock wobble and feel like a toy.

<br>Now I have to buy another...

Missing an end plate

by -

Gave it only 3 stars because the kit was missing the end plate. Thankfully, I had spares in my armoror's kit. Otherwise it was nicely finished and installed without issues.

ANDERSON MANUFACTURING MIL-SPEC STOCK HARDWARE KIT

by -

Was surprised it came with a endplate with sling attachment points. everything else seems to be in order, with no problems.

no good don't buy

by -

It came with a different end plate with ears for slings. The part was way out of spec and would not install straight. The gap between tab on end plate and channel in buffer tube threads was so serious that my stock was canted 30 degrees off center.

It's perfectly fine... it's just a milspec stock kit

by

Bought this as part of my first AR build. It's a stock kit. Parts were fine, price was great, and PA's shipping was fast.

Castle Nut issues

by

Most of the kit seems fine, however, the castle nut was not to spec. When snugging down, the castle nut only made contact to the end plat in one place, as if it was cut at an angle. There was a very visible 1/8" or so gap at the widest non-contact point. Used a spare castle nut I had laying around and it was fine. As another reviewer pointed out, the castle nut has a rich, high gloss finish. I'm sure PA will take care of me, but as for this product, well, I suppose you get what you pay for.

Inconsistent quality

by

The first of these kits that I purchased was of excellent quality. The tube was flawless with a great finish inside and out, the castle nut was phosphated, and the latch plate was the ambi sling compatible model. I like it so much I ordered two more kits. These kits came with the latch plate pictured (no problem, you should get what you order), shiny low quality castle nuts, and tubes with horrible finishes. Micro cracks all over the outside, only finished half way down the inside and inconsistent outside diameter with bulges and dips the length of the tubes.

Well worth the $!!!

by

Buffer tube kit was excellent for the $$$. Already looking for the next build?

Its as expected

by

Bought it when it was on sell... Its as expected and dose its job well...

Not the greatest but will work.

by

The cap and nut had a high gloss paint job while the tube had dull anodizing. Previous purchases of this kit were not like this. It still functions but not what I expected or wanted!

Junk tube

by

Nothing wrong with the spring or buffer, however the tube is a pos. Threads junk and once I finically got it to take in the lower (seekins) it was so loose at the end of the tube I measured 1/4" of play.

Buffer kit.

by

Buffer kit fits and works properly. No issues here!

Buffer tube starting to strip

by

For the price I wasn't expecting perfection but the buffer tube started to strip. You have to make damn sure you have everything in place and held tight when you start putting any torque on the castle nut. Mine is now on there good tight and straight! This kit isn't the best but not the worst I have seen.

Junk x2 (7075 T6 My A$$)

by

I total agree with (Aubrey) as soon as i tighten the castle nut and with very little to no torque (hand tight) the buffer tube began to rotate with the castle nut upon removing the castle nut you could see that the end plate tab totally stripped out the threads to buffer tube making it useless will never buy anything with the name Anderson on it again......CHEAP JUNK

Junk

by

Tightened castle nut and end plate stripped out threads of buffer tube. Now I can twist the stock with my hand. If I torque the castle nut down tight enough to stop the stock winds up cock eyed. Notch on end plate has shallow engagement in groove on buffer tube making it likely to strip when torqued down it appears.

Great for the $

by

Seems pretty well made installed without any issues. The inside of the tube has a bit of soft texture from when it was milled out or whatever (which I don't like as it makes a little more noise than others) and the finish on the buffer is not as great as some more expensive options but those are pretty minor issues. It functions perfectly and that's what really counts. If you're going for a budget build this will work great.

Solid.

by

Good product. Ungodly fast shipping. Ordered Saturday. Arrived Monday. Holy crap! I'm a big Palmetto State Armory user. This has now changed. Have several more parts ordered and they are already on the way. Will be starting the upper soon. I'll be back.

Works great on my 300 Blackout SBR

by

I bought this a couple of weeks ago to complete my Spikes lower receiver. These are quality parts and the price was great. It functions perfectly love it. Thanks PA!

Works as intended

by

Spring rattles way to audible in the tube. Plan on swapping out the kit for another.

milspec buffer

kit came as described picked up for good price

Fast shipping!

by

Can't beat that price. Not sure what happened with the last reviewer but received mine 4 business days after ordering that's good in my books. 7075 for 24 on sale can't beat that. My BCM kit was 3Xs the price!

Shipping speed

by

Parts are fine, but your speed of getting things shipped is not.
