Catalog Page: 332
Class: Class III
Description:

Manufactured in Broken Arrow, Oklahoma, this individually marked and registered auto sear is fitted in a shelf pattern trigger pack, installed in item "B" of this lot and configured to match the housing markings.

Rating Definition:

Excellent, with minor wear. Appears to be in fine working order. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.



B) Heckler & Koch SP89 Host Gun in "MP5 PDW" Configuration

Type: Rifle
Gauge: 9 mm
Barrel: 4 1/2 inch round
Finish: matte black
Grip:
Stock: synthetic

Serial Number:
Catalog Page: 332
Class: Modern Long Gun
Bore Condition: Minor spotting, otherwise bright with strong rifling.
Description:

Developed in 1989 as a semi-automatic pistol variant of the firm's famous MP5K compact submachine gun, this item was later altered to match the "MP5 PDW" (personal defense weapon) configuration and mated with the sear pack described in "A". Hooded post front and four position notched drum rear sights, with the model markings and "IK" (1989) date code on top of the receiver, "8J IN" marked barrel, import marks on the right side of the magazine well, and "S/E/F" selector marking. The magazine well retains a functional paddle magazine catch, with a welded on "shelf", which the trigger housing has been altered to accept. As noted, the sear pack matches the safe/semi/auto markings, with a right handed selector and a bolt carrier modified with a welded-up sear trip to interface with the trigger pack. Fitted with a combination straight foregrip/hand protector, textured pistol grip, and a side folding Choate Tool buttstock.

Rating Definition:

Very good as upgraded and partially refinished to serve as a sear host, with minor handling marks overall. The furniture is very good, with some minor scratches and scuffs. Mechanical adjustment is needed; some play in the trigger housing causes inconsistent engagement between the bolt carrier and trip arm. NOTE: This item is a “host” for a NFA-registered conversion component, and will not be separated from that component for sale or shipment. The serial numbered receiver of this item has not been permanently altered to accept the conversion component, and is not called out by serial number on the paperwork for the conversion component.
