H&K MP5, SP5, HK94 4 Position A3 F Retractable Rear Stock

Debated this versus the newer 2 position A3 vs the older Navy stock which is an iconic look. Researched a bit to find out that this new A3 is superior in performance. Took the plunge and ordered one, NO REGRETS! The new A3 stocks have a stronger buffer for +P and +P+ loads. The 4 position is much more adjustable for different stature people with different arm lengths, variations in sights/placement and to adjust for heavy clothing or tactical vests. I highly recommend the newer stock design and the 4 position.

Very nice!

Best hk brace available!!!!!!!!!

Not sure what HKParts meant when they put this on the description: Please note: That with all HK German stocks the black finish may vary in the sheen and gloss used at the factory. These marks are common on all new production stocks. They may also come ?new? with slight handling marks as they are shipping in bulk and the paint on the rails are fragile. The one they sent me was perfect in every way, not a blemish or variation in the sheen or gloss on mine. Pretty sure I'm not a "special" customer to get one this nice (or am I???). :)

It's exactly what you need to make your SP5 or MP5 perfect but you're going to have a hefty price to pay to join the cool kids club. It's much more solid than I expected, I always thought it wouldn't have support John McClane's weight but now I know that movie got it right. It's surprisingly comfortable to shoot compared to many collapsible stocks though the fixed stock can't be beat for that. Overall, it's a crazy expensive but essential part to an HK SBR or machine gun.

Love it, fast service, excellent quality, and great products.

This stock locks up solid in every position. Fits perfectly on my SP5.

Works fantastic and as stated before there is absolutely no rattle. This stock fits like a glove and works flawlessly.

Great fit, no rattle!
